Description
WO 20121101042
HIGH HEAT RESISTANT COMPOSITION
The present invention relates to a composition that can be used to improve the
fire and high heat resistance of substrates or structures coated with such
composition, in particular compositions that will expand when exposed to high
heat or fire conditions to form a substantially stable and protective
carbonaceous char.
Many materials, such as steel, rapidly lose their strength and fail due to a loss in
structural integrity in a fire. Structural collapse of "high-rise" office blocks, oil
and gas facilities or other infrastructure, and process vessel or pipe work
rupture as a result of a fire can be catastrophic in terms of escalation of the
incident, damage to property, and even loss of life.
Intumescent coatings are used on many structures to delay the effects of a fire.
The coating slows the rate of temperature increase of the substrate to which the
coating is applied. The coating thus increases the time before the structure fails
due to the heat of fire. The extra time makes it more likely that fire fighters will
be able to extinguish the fire or at least apply cooling water before the structure
fails.
Intumescent coatings generally contain some form of resinous binder, for
example a crosslinked high-temperature polymer such as an epoxy resin or a
vinyl toluene / styrene acrylic polymer. The resinous binder forms the hard
coating. If an epoxy resin is present in the binder, the binder also provides a
source of carbon, which, in a fire, is converted to a char.
WO 20121101042
A range of methods is known in the art for treating inflammable or heat sensitive
substrates such as building materials, for example structural wood or steelwork,
interior decorative materials, for example plywood or medium and high density
fiber panels, or insulated electric wiring. In GB 2159522 an ablative coating
system is disclosed comprising a reactive mixture of epoxy and polysulfide
resins, an amine curing agent, inorganic materials, and carbonaceous pre-ox
fibers. This coating can provide thermal protection in a high temperature,
erosive environment.
In US 4965296 a fire retardant coating materials is disclosed that includes a
fluid intumescent material and conductive particles of various sizes.
In US 5925457 an intumescent coating system is disclosed comprising two
different foam components. The two foam components are provided in a
laminate-type arrangement, which puts restrictions to the way this system can
be applied to surfaces that need to be protected from a fire.
In US 6096812 a low density, epoxy-based intumescent fire resistive coating,
having a density below about 1.10 grams/cc, and a method for form ing the
same, are disclosed. This method includes the steps offorming an epoxy-based
intumescent mastic, having minute particles of amorphous silica dispersed
therein. The mastic is then sprayed in droplets on at least one surface of a
substrate to form a low density mastic coating on the surface. The low density
mastic coating then cures to form a low density, intumescent fire resistive
coating. In this publication Chartek® type coating compositions are described.
In WO 91/11498 a system is disclosed based on a combination of
comparatively small amounts (e.g. 3-20 wt %) of exfoliable laminar minerals
WO 20121101042
such as expandable graphite with one or more binders and one or more of a
range of intumescent char-forming materials such as carbonifics, acids and
acid-yielding catalysts, blowing agents, char-formers and stabilisers.
In WO 97/01596 a thin-film intumescent composition is disclosed for protecting
a substrate against fire and thermal extremes, which includes a polymer binder,
a solvent, a carbonific, a spumific, a catalyst, and at least some additives
chosen from a source of carbon, finely divided elemental boron, a metal
stearate adduct with alumina, and a conjugated fatty acid. The compositions
provide chars having greatly increased efficiency, greater thickness, better
physical characteristics including cell structure and physical toughness, and
greater resistance to oxidation by fires and by chemicals present in fires.
In WO 97/19764 a heat ablative coating composition is disclosed comprising an
epoxy silane resin, an epoxy resin, a silicone intermediate, a silicon modified
polyether, an aminosilane, an organometallic catalyst, an organic solvent, water
and a filler. It takes about one week at ambient temperature to cure this coating,
which is relatively long.
In WO 98/03052 intumescent coating compositions are disclosed comprising a
non-silicone based polymer as a binder and a small amount of platinum. The
compositions also comprise tetrafluoroborate salts. In a preferred embodiment,
the binder is an epoxy polysulfide resin.
In WO 20101054984 an intumescent composition is disclosed comprising: A) a
binder comprising (i) a resin comprising a polysiloxane chain or a precursor for
said chain, (ii) optionally an organic resin, and (iii) at least one type of functional
group selected from the group consisting of epoxy, amine, mercaptan,
WO 20121101042
carboxylic acid, acryloyl, isocyanate, alkoxysilyl, and anhydride groups, said
functional groups being present as pendant and/or terminal groups on said resin
comprising a polysiloxane chain or the precursor for said chain, and/or on the
organic resin, provided that if the binder contains alkoxysilyl groups as the only
type of said functional groups, these alkoxysilyl groups are present on the
organic resin, 8) a compound capable of reacting with or catalysing the reaction
between the functional groups, and C) a spumific and a char forming adjunct
With the exception of US 6096812, none of the above patent publications have
resulted in any coating system with properties equal to or even better than one
of the best performing systems that is commercially available at present, viz.
Chartek® 7 and Chartek® 8 (both ex International Protective
Coatings/AkzoNobel). Chartek® 7 is an epoxy-based fire protection coating that
primarily acts as a barrier coating to prevent corrosion of a steel substrate. In a
fire, this coating insulates the steel from reaching critical failure temperatures.
Currently, Chartek® 7 is the only fire protection coating that achieved the
protective coating standard Norsok M501 (revision 5) without the need to apply
a separate topcoat, which means that this product/system 1) provides optimal
protection of the installation 2) with a minimum need for maintenance (so is
maintenance friendly), and 3) is application friendly.
This Norsok M501 test is also referred to as weatherability or durability test
One of the methods to evaluate the fire resistant properties of a substrate is to
expose the substrate to a jet fire in accordance with test method IS022899.
Chartek® 7 provides a protection against a jet fire of approximately 60 minutes
at a dry film thickness of 10mm. There is a clear need for products which
provide protection against a jet fire for longer times, well over 60 minutes at a
dry film thickness of 10mm.
WO 20121101042
It was found that the composition according to the present invention can provide
a substrate protection against a jet fire of more than 80 minutes at a dry film
thickness of 10mm, which is a significant increase and a step change in
comparison to intumescent and/or fire resistant products that are currently
available. It was further found that the composition according to the present
invention also generates less smoke when tested in accordance with IMO
Resolution MSC 61 (67).
Another method to evaluate the fire resistant properties of a substrate is to
expose the substrate to a pool fire, also referred to as hydrocarbon
performance. This hydrocarbon performance can be tested according to 8S476
part 20 (Method for determination of the fire resistance of elements of
construction). The composition according to the present invention also shows a
better hydrocarbon performance than products currently available on the
market.
None of the documents referred to above provide any clear guidance on how a
composition can be obtained that shows a good jet fire resistance in
combination with also a good pool fire resistance. The main reason for this is
that currently little information is known on how the various components in the
composition interact with each other, in particular when they are exposed to the
high temperatures and/or erosive environment of a jet fire or a pool fire. The
products that are on the market show either a good jet fire resistance or a good
pool fire resistance, never a combination of both properties.
Surprisingly, a coating composition was found that shows a superior jet fire
resistance (> 50% better than currently known systems), a very good pool fire
WO 20121101042
resistance, a low level of smoke generation, and a good weatherability
performance. The heat resistant composition in accordance with the present
invention comprises:
a polysulfide,
an epoxy resin,
a compound selected from compounds having a secondary and/or a
tertiary amine group, and compounds having an amide group,
a polysiloxane, and
fibres.
Within the framework of the present invention,
a primary amine group is a group wherein a nitrogen atom is directly
connected to two hydrogen atoms, this can be represented as R NH2
(wherein R1 can be any organic group, except hydrogen)
a secondary amine group is a group wherein a nitrogen atom is directly
connected to one hydrogen atoms, this can be represented as R1R NH
(wherein R1 and R2 can be any organic group, except hydrogen),
a tertiary amine group is a group wherein a nitrogen atom is not directly
connected to a hydrogen atom, this can be represented as R1R2R N
(wherein R1, R2 and R3 can be any organic group, except hydrogen)
an amide group is a group wherein a nitrogen atom is attached to a
carbonyl, this can be represented as R CONR2R3 (wherein R1, R2, and
R3 can be any organic group, including hydrogen)
In general, a fire resistant and/or intumescent composition can be characterised
by ingredients having the following function(s):
a resinous binder,
a source of carbon,
WO 20121101042
a carbon conversion enhancer,
a spumific,
an enhancer for the stability and/or strength of the char, and
various additives to improve wetting/surface tension/mar resistance/etc.
Some of the ingredients in the composition may only have one function, other
ingredients can have two or multiple functions in the composition.
In the composition according to the present invention, the polysulfide is one of
the ingredients of the resinous binder.
Suitable polysulfides can be obtained by the polycondensation of bis-(2-
chloroethyl-) formal with alkali polysulfide. During this reaction, the chain length

and 1 - 50 parts by weight of an aliphatic epoxy resin.
In the composition according to the present invention, the compound selected
from compounds having a secondary and/or a tertiary amine group, and
compounds having an amide group is an ingredient of the spumific, but can also
act as an ingredient for the resinous binder.
A spumific provides expansion gas as it decomposes in the heat of a fire. It is
WO 20121101042
desirable that the spumific gives off gas at a temperature at which the resinous
binder is soft but which is below the temperature at which the char is formed. In
this way, the char which is formed is expanded and is a better insulator. The
compound selected from compounds having a secondary and/or a tertiary
amine group, and compounds having an amide group can be selected from
melamine, melamine formaldehyde, methylolated melamine,
hexamethoxymethylmelam ine, melam ine monophosphate, melam ine
biphosphate, melamine polyphosphate, melamine pyrophosphate, urea,
dimethylurea, butylated urea, alkylated urea, benzoguanamine, glycoluril type
compounds, tris(alkoxycarbonylamino) triazine type compounds, and,
guanylurea.
In one embodiment, the compound selected from compounds having a
secondary and/or a tertiary amine group, and compounds having an amide
group is a methylated melamine or urea resin. In another embodiment, the
composition comprises a mixture of two or more different types of compounds
selected from compounds having a secondary and/or a tertiary amine group,

and Cylink 2000 (All ex Cytec).
Other suitable compounds having a secondary and/or a tertiary amine group,
and compounds having an amide group include dialkylamino alkyl functional
phenolic compounds, such as Ancamine K54 and DMP-30
WO 20121101042
In the composition according to the present invention, the polysiloxane can also
act as an ingredient for the resinous binder
The term "polysiloxane" is defined as a polymer which includes linear,
branched, cyclic, ladder and/or cage structures and has a Si-O backbone with
organic side groups attached to silicon atoms through a carbon or heteroatom
linkage, wherein at least part of the silicon atoms is attached to one, two, or
three oxygen atoms.
Although at least part of the silicon atoms is attached to one, two, or three
oxygen atoms, it is possible for part, but not all, of the silicon atoms to be
attached to four oxygen atoms.
In one embodiment, the polysiloxane is a non-functional polysiloxane, meaning
that the polysiloxane does not carry any functional groups that can react with
other compounds in the composition.
In another embodiment, the polysiloxane is contains hydrolysable groups, such
as alkoxy groups, acetoxy groups, enoxy groups, oxime groups, and amine
groups attached to a silicon atom.
Following the above definition of a polysiloxane, the resin comprising a
polysiloxane chain that is present in the composition according to the present
invention, is either
(i) a polysiloxane as defined above, thus having a Si-O backbone, or
(ii) a resin with an organic backbone with one or more pendant polysiloxane
chains, i.e. chains having a Si-O backbone with organic side groups
attached to silicon atoms through a carbon or heteroatom linkage,
wherein at least part of the silicon atoms is attached to one, two, or three
oxygen atoms. Said chains include linear, branched, ladder and/or cage
structures.
WO 20121101042
In one embodiment, the polysiloxane is a silicon oil. Examples of fluid
polysiloxanes include liquid methoxy-, ethoxy-, and silanol-functional
polysiloxanes with a molecular weight above 400, such as DC 3037 and DC
3074 (both ex Dow Corning), or SY 231, SY 550, and MSE 100 (all ex Wacker).
Other suitable polysiloxanes have both an epoxy functionality and an alkoxy
functionality.
In another embodiment the composition comprises a mixture of two or more
types of polysiloxanes, for example a mixture of two or more types of liquid
polysiloxanes.
In the composition according to the present invention, fibres are one of the
ingredients that can enhance the stability and/or strength of the char . In
general, these fibres should be inert to the various reactions that take place
during the curing/drying of the composition and during high heat or fire
exposure of the composition. Suitable fibres include glass fibres, mineral fibres,
and high temperature resistant man-made fibres, such as carbon fibres and p
aram id and m-aram id fibres.
In the composition according to the invention at least 0,05 wt. % of fibres should
be present to ensure proper jet fire resistance and/or hydrocarbon performance.
(wt. % is relative to the weight of the composition after evaporation of any
solvent that is present in the composition)
In the composition according to the present invention various other ingredients
can be present to improve wetting/surface tension/mar resistance/etc. To
improve the mar resistance, the composition can contain small amounts « 3
wt. % based on the total composition) of methyl silicone resin, e.g. Silres MK
powder (ex. Wacker Silicones).
WO 20121101042
The composition according to all embodiments of the present invention may
further comprise a char-forming adjunct (also called carbon conversion
enhancer) as an intumescent ingredient. A char-forming adjunct promotes the
formation of a char when the composition is exposed to fire. Lewis acids are
believed to perform this function. Preferably, phosphorus compounds such as
ammonium phosphates, phosphonatosilanes, more preferably ammonium
polyphosphate, phosphonic acid, phosphonic acid esters, phosphine oxide or
phosphoric acid are used. It is also possible to use other char-forming adjuncts
instead of or in addition to phosphorus containing compounds. Ammonium
polyphosphate can be used optionally in conjunction with tris-(2-hydroxyethyl)
isocyanurate (THEIC). If THEIC is used, the ratio of THEIC to ammonium
phosphate preferably is between 10: 1 and 1: 1 0 and more preferably between
3:1 and 1 :3.
The char-forming adjunct is preferably present in the composition according to
the present invention in an amount of 5 to 30 wt%, more preferably 10 to 25
wt%, and most preferably 15 to 20 wt%, based on the total weight of the
composition.
The composition might also contain melamine compounds, such as melamine
and di melamine orthophosphate, melamine and di melamine pyrophosphate,
and melamine and di melamine polyphosphate.
A further intumescent ingredient that may be present in the composition
according to all embodiments of the present invention is an additional source of
carbon, i.e. additional to the optional organic resin. Examples of suitable
additional carbon sources are pentaerythritol, dipentaerythritol, polyvinyl
alcohol, starch, cellulose powder, hydrocarbon resins, chloroparaffins, and
phosphated plasticisers.
Fire retardants other than chloroparafins may also be employed in the
WO 20121101042
formulation (such as zinc borate). However, such added fire retardants are not
necessary to achieve the unique properties of the composition according to the
present invention, i.e. a combination of a superior jet fire resistance, a very
good pool fire resistance, a low level of smoke generation and a good
weatherability performance.
The composition of the invention may further contain solvents and/or pigments.
Examples of suitable solvents are di-methylbenzene and tri-methylbenzene.
Examples of suitable pigments include titanium dioxide (white pigment),
coloured pigments such as carbon black, one or more strengthening pigments,
one or more anticorrosive pigments such as wollastonite or a chromate,
molybdate or phosphonate, and/or a filler pigment such as barytes, talc or
calcium carbonate.
The composition may also contain one or more thickening agents such as fine
particle silica, bentonite clay, hydrogenated castor oil, or polyamide wax, one or
more plasticisers, pigment dispersants, stabilisers, mould releasing agents,
surface modifiers, flame retardants, antibacterial agents, antimoulds, low
density fillers, endothermic fillers, char promoters, fluxing aids, and levelling
agents.
The composition may also contain minute particles of amorphous silica with
particle sizes of about one micron or less, preferably about 3 to 500 nm. These
particles assist in reducing the density of the intumescent coating. Examples of
suitable minute silica particles include flame silica, arc silica, precipitated silica
and other colloidal silicas. Preferably, the minute silica particles are particles of
fumed silica. More preferably, the fumed silica is a surface treated silica, for
instance a silica treated with dimethyldichlorosilane or hexamethyldisilazane.
Even more preferably, the amorphous silica particles are polydimethylsiloxane
WO 20121101042
oil-treated fumed silica particles. The composition generally cures at ambient
temperatures, for example _5° to 40°C, and is thus suitable for application to
large structures where heat-curing is impractical when the temperature is low.
The composition of the invention alternatively may be cured at elevated
temperatures, for example from 40° or 50°C up to 100° or 130°C, if so desired.
The hydrolysis of silicon-bonded alkoxy groups depends on the presence of
moisture: in almost all climates atmospheric moisture is sufficient, but a
controlled amount of moisture may need to be added to the composition when
curing at sub-ambient temperature or when curing in very low humidity (desert)
locations. The water is preferably packaged separately from any compound
containing silicon-bonded alkoxy groups.
The composition according to all embodiments of the present invention
preferably has a solids content of at least 50% by weight (wt%), more preferably
at least 80 wt%, and most preferably at least 85 wt%, based on the total weight
of the composition. The solids content is based upon a theoretical calculation of
the solvent in the formulation excluding that which would be released upon
curing.
The Volatile Organic Content (VOC) of the composition as present in a paint
can (that is: prior to cure) preferably does not exceed 250 g/I and most
preferably is less than 100 g/I solvent per litre of the composition.
The above values refer to those of the complete composition. Hence, if the
composition has the form of a 2-pack composition, they refer to the solids
content and the VOC of the composition after the two packs have been mixed.
The composition according to all embodiments of the present invention can be
applied on various substrates. It is particularly suitable to be applied on metal
substrates, more in particular steel substrates. Due to the strength of the char,
the intumescent may also protect structures from jet fires, i.e. high-temperature,
high heat flux, high-velocity flames. Some compositions according to the
WO 20121101042
present invention can thus also be applied in jet fire resistant zones.
The composition can be applied by conventional methods for applying
intumescent compositions, such as spraying or troweling.
In one embodiment of the invention, the composition according to claim 1
comprises
- 25 wt. % of a polysulfide or a mixture of polysulfides,
2 - 20 wt.% of an epoxy resin or a mixture of epoxy resins,
2 - 20 wt. % of a compound or mixtures of compounds selected from
compounds having a secondary and/or a tertiary amine group, and
compounds having an amide group,
1 -10 wt.% of a polysiloxane or a mixture of polysiloxanes, and
0.5 - 10 wt. % of fibres or a mixture of fibres,
wherein the wt. % is relative to the weight of the composition after evaporation of
any solvent that is present in the composition.
In a further embodiment of the invention, the composition comprises
- 25 wt.% of a char-forming adjunct
18 - 24 wt.% of a polysulfide or a mixture of polysulfides,
15 - 18 wt. % of an epoxy resin or a mixture of epoxy resins,
11 - 18 wt. % of a compound or mixtures of compounds selected from
compounds having a secondary and/or a tertiary amine group, and
compounds having an amide group,
7 - 10 wt. % of an additional source of carbon,
1 - 5 wt.% of a polysiloxane or a mixture of polysiloxanes, and
1 - 5 wt. % of fibres or a mixture of fibres,
wherein the wt. % is relative to the weight of the composition after evaporation of
any solvent that is present in the composition.
WO 20121101042
The composition can be used as a coating to coat a substrate in whole or in part
to give the substrate protection against high heat or a jet fire. The composition
should at least be applied to the side of the substrate that is exposed to the high
heat or jet fire. The composition is in particular suited to provide fire protection
to steel, galvanised steel, aluminium, glass reinforced plastic, wood or concrete
substrates.
In addition to what was already indicated above, the composition according to
the present invention provides a number of advantageous properties in
comparison to systems that are currently on the market and/or fire protection
systems that are disclosed in various documents.
- No need to use a mesh.
Many fire protection systems that are currently on the market need a mesh
reinforcement to provide sufficient structural integrity when exposed to a jet
fire. The system according to the present invention shows good structural
integrity even without a mesh. However, a mesh can be used to reinforce the
system. In principle any mesh can be used that is capable of maintaining its
structural integrity at a temperature in excess of 480°C. Examples includes
carbon mesh (mesh comprising a carbon yarn or a carbon yarn precursor), or
a mesh comprising other types of high temperature resistant materials or a
mesh comprising a mixture of high temperature resistant material, such as
carbon yarn and glass fibres, carbon yarn and steel wire, carbon yarn and
ceram ic fibres, steel wire and ceram ic fibers, etc.
- Borate free system.
In some fire protection systems, borates are used as one of the components
in the system (see e.g. WO 98/03052). Borates have been proposed for
WO 20121101042
classification as reprotoxic category 2 products in accordance with EU
Directive 67/548/EEC. For the system according to the present invention it is
not necessary to add any borates.
- The system is very durable without the need to apply a separate topcoat.
The composition according to the present invention will probably meet the
requirements of Norsok M501 (revision 5) without the addition of a separate
topcoat. This means that it is sufficient to provide the coating according to the
present invention not only to give a good corrosion and fire protection to a
steel surface, but also that it is not necessary to overcoat the composition to
get a good appearance with good durability, even when exposed to harsh
conditions.
- Can be applied to a wide range of (steel) column sizes without losing its
properties.
- Halogen free system.
It is not necessary to add any halogen containing components to the
composition of the current invention.
- Fast curing system (can be overcoated within hours)
