Definitions
- This invention is concerned with improving the adhesion of coatings to substrates. More particularly, though not exclusively, this invention is concerned with a method for improving the adhesion of a coating to aluminum, galvinized steel, vinyl, PVC, TPO, Hypalon®, pressure treated wood, plywood and bitumenous substrates, as well as chalky acrylic coated surfaces of such substrates.
- EPDM and asphalt membranes encompass about 70% of the total roofing market.
- a large portion of the remaining market consists of various metal substrates, such as aluminum and galvanized steel.
- Other substrates used comprise single ply substrates made from PVC (polyvinyl chloride), TPO (thermoplastic polyolefin) and Hypalon®.
- Hypalon is a trade name for a sysnthetic rubber produced by DuPont Dow. It is described as a chlorosulfonated polyethylene and is produced as white chips. It can be used for the production of many products, including sheet roofing substrates and protective / decorative coatings.
- Still other substrates used comprise spray applied polyurethane foam. All of these substrates can benefit from the use of a coating to improve aesthetics, reduce energy costs, and improve durability.
- the architectural coatings industry use paints to coat similar substrates used in the roofing market.
- the paint market has somewhat different performance criteria than coatings used in roofing; i.e. paints are applied thinner (3 to 8 dry mls versus 20 to 25 dry mls for roof mastics) and paints are not expected to perform in areas where water ponding is prevalent.
- Many of the metals used in the roofing market are used for applications in the architectural markets. Metal used in both the architectural and roofing markets can be factory applied as well as painted at the job site.
- the architectural coatings industry utilize many other substrates, not prevalent in the roofing market. Pressure treated wood, chalky acrylic and factory applied coatings to aluminum and vinyl substrates are examples of commonly used materials that can be painted. Coating these substrates is necessary because of degradation and weathering. Weathered substrates that have been previously painted frequently have chalky surfaces that are difficult to adhere to, yet need to be re-coated to prevent degradation of the substrate.
- the key criteria for the coating is the ability of this coating to adhere well to the substrate. Cleaning with water before coating may improve adhesion of the coating as compared to not rinsing the substrate surface and cleaning with detergents has also shown to help.
- the detergent of the present invention exhibits an ability to significantly improve adhesion properties of substrates to coatings. Several substrates have shown to be difficult to adhere to, such as aluminum, galvanized steel, pressure treated wood and weather treated pine. The use of the aqueous detergent composition and method of the present invention has improved adhesion to such substrates.
- a coating system which displays good adhesion and superior resistance to blistering, especially when exposed to ponded water is disclosed in US-A-5059456.
- the tiecoat consists of a water-insoluble latex polymer and multivalent metal ion, wherein the latex polymer comprises units such as would result from preparation from a monomer mixture comprising at least 20 weight %, based on the weight of the monomer mixture, of at least one hydrophobic monomer selected from the group consisting of (C 4 -C 20 )-alkyl methacrylates and (C 8 -C 20 )-alkyl acrylates, and from 3.0 weight % to 7.5 weight % of methacrylic acid, based on the weight of the monomer mixture, and where the latex polymer has a glass transition temperature of from -20°C to 5°C, and where the molar ratio of the multivalent metal ion to the methacrylic acid in the latex
- the tiecoat is applied to a membrane before subsequent application of a coating.
- This system offers properties of adhesion and resistance to blistering which are superior to conventional mastic systems on bituminous membranes, there is no disclosure of coating aluminum, galvinized steel or pressure treated wood substrates.
- a method for improving the adhesion between a coating and a substrate which method comprises:
- the substrate for application of the invention is aluminum, galvinized steel, vinyl, PVC, Hypalon®, pressure treated wood or plywood.
- the aqueous detergent composition of the present invention is allowed to sit for five (5) minutes, followed by the rinsing step.
- the rinsing step includes both a power wash at a pressure of 193 x 10 5 N/m 2 (2500 psi) and a non-presured rinse.
- the coating composition may be any composition traditionally used in coating such sunbstrates, preferably comprising a water-insoluble latex polymer binder, having a glass transition temperature of from -45°C to 50°C (as measured by the Fox equation), which is preferably acrylic or styrene/acrylic.
- the composition will comprise at least one or more of the following components: pigments, extenders, dispersants, surfactants, coalescents, wetting agents, thickeners, rheology modifiers, drying retarders, plasticizers, biocides, mildewicides, defoamers, colorants, waxes, dirt pick-up retarders, adhesion promoters, zinc oxide and solid silica.
- the coating composition is preferably an architectural roof coating composition or mastic coating composition.
- the binder used in the coating composition is preferably a commercially available binder useful for such applications, such as a binder selected from the group including Rhoplex AC-261, Rhoplex EC-1791, Rhoplex 2019R and Rhoplex EC-2885 available from Rohm and Haas Company; Acronal NX 3250 available from BASF AG and DA26NA available from Dow. More preferably, the binder is selected from the group including Rhoplex AC-261, Rhoplex EC-1791, Rhoplex EC-2885 and Acronal NX 3250. Rhoplex AC-261 and Rhoplex EC-1791 are the most preferred coating compositions.
- the aqueous detergent composition comprises from 1 to 10%, preferably 2 to 8 %, more preferably 3 to 6%, by weight of said composition of a mono- or polyphosphate or a mixture of such phosphates, preferably selected from the group consisting of trisodium phosphate, sodium tripolyphosphate and tripotassium phosphate. Trisodium phosphate is the most preferred.
- the aqueous detergent composition comprises from 1 to 10%, preferably 2to 8 %, more preferably 3 to 6%, by weight of said composition of a meta-, ortho- or para-silicate or a mixture of such silicates, preferably selected from the group consisting of sodium metasilicate and potassium metasilicate. Sodium metasilicate is the most preferred.
- the phosphates and silicates useful in the detergent composition are those commonly used in conventional detergent compositions, such as in dishwashing and clothes-washing detergents.
- the aqueous detergent composition may also comprise other components typically found in aqueous detergent composition.
- the composition may comprise up to 5%, preferably up to 2%, by weight of at least one compound selected from the group consisting of octylphenoxy polyethoxy ethanol, octyphenoxy polyethoxy ethylphosphate, polyethylene glycol and phosphoric acid.
- the aqueous detergent composition has a pH of above 8, preferably a pH from 9 to 14, and most preferably a pH from 12 to 14.
- the detergent composition may be spread over the surface by spray application methods or with the aid of a stiff brush.
- the detergent composition should preferably be left to stand in contact with the surface of the membrane for a minimum of five (5) minutes. For example, though an improvement in adhesion of a coating may be measured when the detergent composition is left to treat the surface for less than 30 seconds, the best results are achieved when the detergent composition is allowed to contact the surface for at least 5 minutes. A contact time significantly over 5 minutes will tend not to lead to any significant further improvements in adhesion, though in practice contact times may be 10 to 30 minutes depending on the size of the substrate and the speed of the operator. Permitting the detergent to dry on the surface before rinsing may not be detrimental to the method of the present invention, provided the surface is rinsed well afterwards to remove the detergent.
- High efficiency rinsing may involve the use of a stiff brush and/or the use of a high pressure hose.
- the high pressure hose will release rinse water at 193 x 10 5 N/m 2 (2500 psi).
- the coatings are subjected to dry and wet adhesion tests. These are performed in accordance with ASTM Protocol D903.
- An aqueous detergent composition with the formulation indicated in Table 1, was prepared by mixing the components in the prescribed amounts in a pail. The composition was mixed in the pail until all components appeared to have dissolved.
- the aqueous detergent composition was prepared in in accordance with the present invention and has a pH above 13.
- Aqueous Detergent Composition Detergent Components Parts by Weight Sodium Metasilicate 5 Soap 2.4 Trisodium phosphate 5 Water 87.8
- Example 3 Various substrates, as shown in Example 3, were laid flat on a surface. The upper surface of each substrate was then washed with tap water using a high pressure hose. After washing with water, 30 cm 2 sections of each substrate was then treated with the detergent composition of Example 1, by spray application of about 100 cm 3 of detergent composition over the surface to be treated and brushing the composition over the surface and allowing it to stand for 5 minutes. Then the detergent composition was washed away with tap water from a high pressure hose at 193 x 10 5 N/m 2 (2500 psi).
- Premix B Premix the following ingredients and add slowly while stirring. Water 5.76 (12.7) Texanol 2.72 (6.0) Skane M-8 1.36 (3.0) D.
- Premix C Premix the following ingredients and add slowly while string. Mix for a minimum of 15 minutes or until consistency is smooth. Propylene Glycol 4.53 (10.0) Natrosol®250HR 1.81 (4.0) E.
- the tape is rubbed with an eraser to assure good contact over the test area, and then using the overlap for grip, the tape is pulled quickly at a 180° angle from the substrate. Then immediately determine knife peel adhesion. These tests should be performed as quickly as possible because adhesion improves with drying exposure in air.
