26-10	BLACK LOW GLOSS WATER BASED PAINT
GENERAL DESCRIPTION Pruett-Schaffer’s #26-10 Black Paint is an air drying, modified water reducible alkyd paint. It is designed to be used as a primer or low gloss DTM finish coat for metal substrates. The cured film exhibits good flexibility and corrosion resistance, and excellent adhesion to a wide variety of metal substrates. RECOMMENDED USES This product was originally developed as a direct-to-metal corrosion resisting one coat low gloss enamel for OEM radiators. It can be used on equipment and machinery, sheet and tube stock, shelving, axles, bins and tanks as a primer or low gloss finish coat. It’s fast drying and exhibits good application characteristics and adhesion to a wide variety of substrates including minimally prepared cold rolled steel, castings, forgings, aluminum, and existing coatings. Not recommended for immersion service or for areas subject to temperatures in excess of 300 ⁰F. The paint is not flammable and has very low toxicity. SURFACE PREPARATION Apply as a direct-to-metal topcoat or as a primer. For best results in DTM service, substrates should be blasted to SSPC-SP-6 minimum, with a 1 mil blast profile. Feather all rough or sharp edges. This coating is very tolerant of less than perfect surface preparation however, so chemical cleaning, water blasting, or even hand or power tool cleaning may be sufficient, depending on the level of service required. At a minimum for acceptable performance, all surfaces to be coated must be clean, dry and free of oil/grease, loose rust/paint, weld spatter, burning slag, dust, and chalk. THINNING Under normal conditions no thinning is necessary or desirable. Thin if necessary for proper spraying with an 80/20 mixture of water/butyl cellosolve		(Pruett-Schaffer thinner #98-8937). Add thinner a little at a time with constant gentle agitation to a maximum of 5% by volume. APPLICATION EQUIPMENT This paint may be applied dip tank application, air-assisted or airless spray. Apply 1 to 1.5 mils dry film thickness if used as a primer or direct-to-metal. When using dip tank application, contact Pruett-Schaffer for further information regarding pH and viscosity maintenance requirements of dip tank. DRYING TIME Dries tack free in 15-45 minutes at 77 ⁰F and 50% Relative Humidity. Light handling may be possible in 90 minutes. High humidity will prolong dry time more so than low temperatures. To speed the dry time good air movement over the work and local exhaust is recommended. Heat lamps or forced warm air drying will reduce dry time in cold shops. CLEANUP Clean equipment with warm soap and water before the film dries or butyl cellosolve mixed with water 20/80 mixture. Run ethyl alcohol through spray guns after cleaning to prevent corrosion of steel parts. ENVIRONMENTAL This product meets current air pollution regulations regarding hydrocarbon and ozone reactive emissions. It contains no lead or chromate.
