28-62	THOMPSON NEW RED WATERBASED QUICK DRY ENAMEL

GENERAL DESCRIPTION Pruett-Schaffer’s #28-62 Red Enamel is an air drying, water reducible alkyd paint. It is designed as a spray- or brush-applied, high gloss, exterior finish coat for metal substrates. The cured film exhibits good flexibility and corrosion resistance, abrasion resistance, and high distinctness of image. RECOMMENDED USES This product is recommended as a maintenance coating for equipment and machinery, sheet and tube stock, shelving, axles, bins and tanks. It 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 over primer (follow primer surface preparation instructions) or direct-to-metal. 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 by brush, roller, dip tank application, air-assisted or airless spray. Brushes should be of polyester or nylon construction. Use roller covers with ^3/8 to ^1/4 inch nap. Use spray tips of 0.015-.020 inch. Apply 1 mil dry film thickness if over primer, 1.5-2.0 mils dry film thickness if 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 30-60 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. 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, chromate, or zinc.
