15-13037	BLACK EPOXY TOPCOAT
GENERAL DESCRIPTION Pruett-Schaffer’s #15-13037 Black Epoxy Topcoat is a two component, phenalkamine cured epoxy where chemical resistance is needed. It is designed as a high gloss, spray applied, corrosion resistant, heavy duty, topcoat. It exhibits excellent adhesion over a wide variety of substrates, and exceptional corrosion, water and chemical resistance with the ability to cure at much lower temperatures than conventional epoxies. RECOMMENDED USES Use to protect machinery, tanks, and structures from corrosion in aggressive environments where chemicals, salt, water, fuels, and oils are present. Formulated to allow high film build in one pass to protect hard to cover sharp edges. May also be used as an encapsulation coating. This formula will chalk on long term exposure to sunlight. SURFACE PREPARATION For severe service, metal substrates should be blasted to an SSPC-SP-10 white metal blast with a 1.5 +/- .5 mil blast profile. An SP-6 commercial blast may be sufficient for many repair or DTM applications with less severe requirements. This coating is very tolerant of poor surface preparation; for tightly adhering existing coatings, degreasing and hand tool cleaning, power washing, brush blasting, sanding, or a combination of these methods may be acceptable. All surfaces to be coated must be clean, dry and free of oil and grease, loose rust and paint, weld spatter, burning slag, dust, and chalk.		MIXING INSTRUCTIONS Mix 4 parts by volume #15-13037-A with 1 part 15-B Hardener. Mix at slow speed to avoid entraining air into the paint. Use at once, there is no induction time. Do not reuse previously used mixing containers; partially cured material will greatly accelerate the cure of the freshly mixed paint resulting in dramatically reduced pot life. THINNING Thin if necessary for spraying with xylol or toluol. Add a little solvent at a time to the mixed system with constant gentle agitation to a maximum of 5% by volume. APPLICATION EQUIPMENT May be applied by brush or airless spray. Airless spray gives the best results, use .015-.020 inch tip size. Apply 7-8 mils wet film thickness to yield 3-4 mils dry film thickness. Brushes should be of polyester or nylon construction. CURE TIMES & TEMPERATURES Cures set-to-touch in 1.5-3 hours at 77 ⁰F, approximately 2 hours at 70 ⁰F. Topcoat within 8-48 hours or reduced adhesion of the second coat may result. Allow 7-10 days cure at 70 ⁰F before placing into severe service, longer if ambient temperature is lower. Recommended minimum application temperature is 0 ⁰F. Below 40 ⁰F add cold weather accelerator (Pruett-Schaffer part number #13-13715) at a rate of 1 pint per 5 gallons mixed system; this will result in a 24-48 hour cure time. CLEANUP Clean equipment with xylol or toluol before the film cures.	ENVIRONMENTAL This product meets current air pollution regulations regarding hydrocarbon and ozone reactive emissions. It is VOC compliant for the architectural maintenance industry, and contains no lead, chromate, or zinc.
