10-13509	BLACK EPOXY PRIMER

GENERAL DESCRIPTION Pruett-Schaffer’s #10-13509 Black Epoxy Primer is a two component, phenalkamine-cured epoxy for use as a heavy duty maintenance primer. It is designed as a medium gloss, brush or spray applied, corrosion resistant, ferrous metal coating. It exhibits excellent adhesion over a wide variety of substrates, and exceptional corrosion and chemical resistance. 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. Suitable for topcoating with a wide variety of epoxy, urethane, vinyl, or acrylic emulsion topcoats. May also be used as an encapsulation coating. This primer will chalk, topcoating is necessary for long term weathering exposure. 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 #10-13075-A with 1 part 10-B Hardener. Mix at slow speed to avoid entraining air into the paint. Use at once, there is no induction time. 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, roller or airless spray. Airless spray gives the best results, use .015-.020 inch tip size. Apply 5.5-7.5 mils wet film thickness to yield 3-4 mils dry film thickness. Brushes should be of polyester or nylon construction. Application with a cup type spray gun is not recommended. CURE TIMES & TEMPERATURES Cures set-to-touch in 1-2 hours at 77 ^0F, approximately 1 hour at 90 ^0F. Topcoat within 4-48 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. This product will cure below 30 ^0F. For faster cure below 40 ^0F add cold weather accelerator (Pruett-Schaffer part number #14-13715)	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 most industrial purposes, and contains no lead or chromate.
