Definitions
- the present invention relates to one-part and two-part adhesives with low volatile organic content for use roofing seams.
- the roofing substrate is a concrete, light weight concrete, wood, gypsum, wood fiber or steel roof deck.
- the roofing membrane is used to seal and protect the roof deck from environmental weather conditions and is placed over insulation boards, which provide insulative qualities.
- the insulation boards are typically secured to the roofing substrate or roof deck via an adhesive composition or fasteners.
- the roofing membrane may be made of various materials, such as polymeric materials including EPDM (ethylene propylene diene M-rubber), Mod Bit (Modified Bitumen), TPO (thermoplastic polyolefin), or polyvinyl chloride (PVC).
- the roofing membrane may also be a composite material that includes EPDM or TPO.
- the roofing membrane is adhered overtop insulation boards or panels using an adhesive composition such as mopping asphalt (typically Type III or Type IV) or other conventional adhesive compositions. Conventional adhesives normally are required to be applied to both the roofing membrane and the substrate.
- VOC volatile organic compounds
- a roofing system includes a first membrane, second membrane and an adhesive layer with no VOC content. A portion of the second membrane overlaps a portion of the first membrane. The adhesive layer directly adheres the overlapping portions of the first membrane and the second membrane together.
- FIG. 1 shows a cross-sectional side view of overlapping membranes adhered to a substrate with an adhesive composition in accordance with the principles of the present invention.
- the adhesive composition can be a one-part adhesive, or the first and second components of the adhesive composition are prepared and packaged separately, and then combined in the proper ratio for application at a job site.
- the adhesive composition 22 is applied between the polymeric roofing material 20, such as, for example, EPDM, and a roof-deck substrate 18.
- the adhesive composition can be allowed to cure for a desired period of time at a desired temperature to obtain optimum bond strength.
- the overlapping sheets or membranes 20 may then be joined with a splice adhesive 1 1 at the time the roofing material 20 is applied to the substrate 18 or after the adhesive composition 22 is cured to form a continuous membrane.
- the splice adhesive 1 1 can be made of the same composition as the adhesive composition 22.
- the implementation shown in FIG. 1 does not require the overlapping sheets to be primed prior to the application of the splice adhesive 1 1 . Further the implementation does not require the use of a seam tape as commonly employed to form a seal between the overlapping sheets 20, since the strength of the seal between the overlapping sheets 20 is as strong as the bond between the sheets 20 and the substrate 18 with the use of the adhesive composition 22.
- the formation of the seam formed with the sheets 20 is primerless so that the sheets do not need to be primed before joining the sheets together to form the seam. Also, an additional tape layer is not required to join the sheets together. Further note that the implementation is not limited to the use of the adhesives described below.
- the primerless seam can be formed with other technologies, such as, but not limited to, a polyurea or epoxy type composition, or any other suitable adhesive composition.
- the adhesive composition is either a one-part or a two-part reactive adhesive composition.
- the adhesive composition generally includes a polyol, a pre-polymer, a catalyst, and may or may not contain an adhesion promoter.
- the polyol may be any compound conventionally used in the production of polyurethanes having at least one isocyanate-reactive functionality. These polyols include glycols, diols, mono alcohols or multi-functional alcohols.
- One exemplary polyol suitable with the composition of the present invention includes an ortho phthalate-diethylene glycol based aromatic polyester polyol commercially available from Stepan under the designation STEPANPOL PS- 2352.
- Another exemplary polyol suitable with the composition of the present invention includes a di-functional polyether diol commercially available from Huntsman under the designations JEFFOL PPG-1000 and JEFFOL PPG-2000.
- Another exemplary polyol suitable with the present invention includes a multifunctional polyether polyol commercially available from BASF under the designation PLURACOL SG360. Chemical derivatives and combinations of polyols may also be employed in the composition without departing from the scope of the present invention.
- the polyol comprises from about 30% to about 50% by weight of the composition.
- the prepolymer or polymer precursor may be any polyurethane prepolymer formed by combining an excess of diisocyanate with a polyol to yield a diisocyanate prepolymer.
- the prepolymer reacts like a diisocyanate but with several important differences. When compared with the original diisocyanate, the prepolymer has a greater molecular weight, a higher viscosity, a lower isocyanate content by weight (%NCO), and a lower vapor pressure.
- One exemplary prepolymer suitable with the composition of the present invention includes a moisture cure prepolymer commercially available from Huntsman under the designation RUBINATE 9272.
- Another exemplary prepolymer suitable with the composition of the present invention includes a 4,4'-MDI prepolymer commercially available from Huntsman under the designation RUBINATE 1209. Combinations of prepolymers and commercially available prepolymers or modified prepolymers may also be employed in the composition without departing from the scope of the present invention. In one embodiment, the prepolymer comprises from about 30% to about 70% by weight of the composition.
- the catalyst may be a metal or an amine based urethane catalyst. It is preferably amine based, more preferably a diazole, and even more preferably an imidazole.
- One exemplary catalyst suitable with the composition of the present invention includes 1 -methylimidazole, commercially available from Air Products and Chemicals, Inc. under the designation IMICURE AMI-1 .
- a secondary catalyst can also be used.
- An example includes a quaternary ammonium salt, Dabco TMR-3, commercially available from Air Products and Chemicals. Combinations of catalysts may also be employed in the composition without departing from the scope of the present invention.
- the catalyst comprises from about 0.5% to about 5% by weight of the composition.
- the blowing agent may be reactive or non-reactive.
- Non- reactive blowing agents include hydrocarbons and hydrofluorocarbons.
- Reactive blowing agents react with the isocyanate group which produces carbon dioxide.
- the carbon dioxide generation produces cellular structure within the adhesive.
- the application of the membrane will crush the adhesive thereby releasing the generated carbon dioxide.
- Water is a commonly used reactive blowing agent in two-part polyurethanes. When water is included in the B side of a two-part polyurethane, the water reacts with the A side components upon mixing of the A and B sides. Additionally, water is not considered a VOC or solvent.
- the adhesive composition may include adhesion promoters such as chlorinated waxes, chlorinated paraffins or chlorinated polyolefins.
- adhesion promoters such as chlorinated waxes, chlorinated paraffins or chlorinated polyolefins.
- An example is Paroil 60H, commercially available from Dover Chemicals.
- the adhesive composition may further include other additives, such as, for example, tackifiers, fillers, plasticizers, surfactants, rheology modifiers, viscosity modifiers, and thixotropic agents.
- Fillers, plasticizers, rheology modifiers, surfactants, and thixotropic agents may be used to alter the liquid viscosity to either or both of parts A and B, optimize mixing properties during dispensing, enhance air entrainment, improve wet out, and improve flow properties of the adhesive during application.
- fillers include silica particles and talc.
- plasticizers include process oils and phthalates.
- rheology modifiers include organoclays, natural clays, and fumed silica.
- An exemplary organoclay is CLAYTONE APA available from Southern Clay Products.
- the surfactants may include silicone based or non-silicone based compounds.
- Tackifiers may be added to improve initial green strength and may be selected, for example, from a group including polyterpenes, rosin esters, phenolic resins, hydrocarbon resins, and hydrogenated resins.
- the amount of the components included in the composition is selected to balance tack, cure speed, and adhesion strength of the adhesive.
- the embodiments presented exhibit adhesive tack when cured and the foam adhesive is substantially soft with a low modulus. The low modulus allows for diffusion of the adhesion promoter to the substrate surface and improves heat aged adhesive strength.
- the "A" side and “B” sides are mixed so that the ratio of the reactive components, ie, ratio of "A" side isocyanate groups to "B" side hydroxyl groups, is greater than 1 .5:1 .
- This ratio is also known as the Isocyanate index and stoichiometrically one isocyanate group reacts with one hydroxyl group.
- this Isocyanate index and the prepolymer incorporated combine to produce a soft, non-rigid adhesive.
- the adhesive composition is prepared by mixing the components prior to application on a substrate. In a one-part adhesive configuration, the components are mixed prior to packaging into a single container. The adhesive is then dispensed or otherwise applied to the roofing substrate or the roofing membrane and is cured in-situ via moisture cure. Due to the reactive nature of the adhesive composition, the adhesive composition may be applied in ribbon or bead method and may be applied to only one side of the substrate or roofing membrane. Additionally, the adhesive compositions provided herein are sprayable. In some of the adhesive composition examples described below the sprayability of the adhesive composition is facilitated using equipment that is capable of modifying the viscosity of the adhesive through the application of heat or like methods.
- the adhesive is formed by combining two separate compositions or blends just prior to application on the roofing substrate.
- the two parts include a "B side” or resin side and an "A side” or prepolymer side.
- Each of the sides is packaged separately and is mixed by an applicator prior to applying on the roofing substrate.
- the A and B side components may be packaged in several ways. For example, each may be stored in a collapsible bag disposed within a box such as Cubitainer® by Hedwin or Cheertainer® by CDF, stored in rigid containers such as drums or barrels, paired in cylinders, or in flexible, fully compressible structures such as collapsible tubes that dispense the materials.
- the B side includes the polyol and the catalyst and the A side includes the prepolymer.
- the adhesive once mixed, is dispensed or otherwise applied to the roofing substrate or the roofing membrane to splice adjacent membranes together. During mixing, and after mixing, the components react to form a polyurethane adhesive having suitable physical properties. Due to the reactive nature of the adhesive composition, the adhesive composition may be applied in ribbon or bead method and may be applied to only one side of the substrate or roofing membrane. As noted above, the A Side and B Side components are preferably mixed by an applicator just prior to being dispensed or otherwise applied to the roofing substrate.
- Forms of application include using a cartridge, using low pressure pumping of the two components and mixing them with a static mixer, or using high pressure tanks that are brought to about 500-1500 psi with an inert dry gas, such as Nitrogen.
- an inert dry gas such as Nitrogen.
- the A and B side materials are metered as two individual components and brought together and mixed by high pressure impingement or by a static mixer and then applied in a bead or ribbon form.
- the "A" and "B" side components are generally mixed in a ratio of 1 :1 by volume, however the ratio may range from about 10:1 to about 1 :10.
- the A Side components and B Side components react to form a polyurethane adhesive having suitable physical properties.
- the adhesive composition is applied in discrete beads or ribbons overtop the roofing substrate, such as the insulation boards or roof deck or roofing membrane.
- the roofing membrane is rolled or otherwise positioned overtop of the adhesive composition and the roofing substrate. Overlapping sheets as shown in FIG. 1 are then joined together with the splice adhesive 1 1 , which is typically the same adhesive composition.
- the adhesive composition then cures and secures the roofing membrane to the roofing substrate, as well as securing adjacent roofing membranes together.
- the roofing substrate and the roofing membrane may be untreated, i.e., no primer or membrane fleece back is required to achieve the desired adhesive strength. Therefore, no fleece backing or primer needs to be applied during membrane production in the factory or during membrane installation at the job site.
- the overlapping membranes also do not need to be treated with a primmer before applying the splice adhesive.
- the adhesive composition can be a one-part configuration.
- the adhesive compositions can have a low modulus of elasticity.
- the adhesive can have a modulus of about 121 .5 psi.
- the adhesive can also have soft and flexible characteristics that promote mobility of the chlorinated paraffins within the adhesive.
- the method of adhering a "neat" EPDM roofing membrane to a roof member as well as forming a seam between adjacent membranes provides several advantages over existing methods.
- the present method provides a VOC free application using curable chemistry between two water-impervious membranes.
- the present method does not require a fleece backing or priming to adhere the EPDM roofing membrane to the roof member.
- the two-part adhesive exhibits a slow reaction initiation time to allow greater wet out of the substrates for improved adhesion.
- Some imidazole structures permethylated nitrogen act as latent catalysts and are more effective after heat aging of the polymer.
- Other imidazole structures active hydrogen
- Various two-part adhesives exhibit an acceptable cure time of the adhesive which allows for enough green strength to resist wind up-lift forces on a roof. (This improvement is from polymer viscosity build and tensile strength increase.)
- the two-part adhesive can exhibit an acceptable cure time of the adhesive to lock down the membranes to allow normal activities on a roof.
- the two-part adhesive in some implementations has an NCO to OH ratio resulting in a soft polymer with a modulus of less than 500 psi and is tacky with a T-peel breakaway strength of greater than 0.5 pli.
- the two-part adhesive can contain an MDI isocyanate pre- polymer having a high 2-4' content which exhibits a slow reaction initiation time to allow greater wet out of the substrates for improved adhesion. (This is due to a balance of 4-4' MDI with 2-4' MDI allowing for fast polymer formation from 4-4' and slower reaction and good wet-out due to steric hindrance of the 2-4'.) Certain two-part adhesives contain Di-ethanol amine or other additives which disrupt the hard/soft segment blocks of the polyurethane adhesive resulting in a soft polymer with good peel strength.
- the two-part adhesives can contain an acid composition that can alter the surface tension or chemistry of the adhesive or membrane allowing for better wet out or creation of reactive sites and improved adhesion.
- the adhesive compositions described above may or may not include paraffins or other adhesion promoters. Any of the compositions may include chain extenders such as, for example, glycerin, di- ethylene glycol etc. for back end cure speed improvements.
- chain extenders such as, for example, glycerin, di- ethylene glycol etc.
- the addition of glycerin or similar chemistries provide a formulation that performs as a roofing adhesive over a wide application temperature range. This allows sufficient we- out time during the initiation of the reaction time to allow for adhesive to the roofing substrate.
- the formulation with glycerin or similar chemistries exhibits acceptable completion of reaction to make the membrane resistant to wind up-lift forces in a timely manner.
- the application temperature range for these compositions have a range from about 0°F to about 190°F.
- the adhesive compositions may be pressure sensitive adhesives (PSA).
- PSA pressure sensitive adhesives
- Such adhesives can be readily dispensed as a liquid that cures to its final form within a desired period of time with final physical properties (i.e. pressure sensitive adhesive) that allow it to adhere to, for example, a polymeric sheet with adequate bond strength to resist application stresses.
- compositions can include high molecular weight polymer additions such as tackifiers and rheology modifiers.
- high molecular weight polymer additions such as tackifiers and rheology modifiers.
- the reduction or elimination of entrapped air can be obtained through polymer cure speed, polymer rheology or the method of applying the adhesive. For example, employing faster polymer viscosity increase or use of the spreader to trap less air between membranes.
