GENERAL DESCRIPTION Pruett-Schaffer’s #34-12907 Black Enamel is a high gloss, air drying, solvent based alkyd paint. It is designed as a spray applied, direct-to-metal finish coat. It exhibits good flexibility, corrosion resistance, and exterior durability. RECOMMENDED USES This product is recommended for general maintenance use on railcars, storage tanks, machinery, and other steel equipment wherever a good quality alkyd finish is needed. It exhibits exceptional adhesion to a wide variety of substrates including minimally prepared cold rolled steel, forgings, castings, and existing coatings. This coating is specially recommended for use over rough surfaces or where extensive surface preparation will not be performed, as the high build finish of this paint will hide many of the surface defects that would be readily apparent with a lower solids gloss paint. Not recommended for immersion service or for areas subject to severe chemical exposure. SURFACE PREPARATION For severe service, metal substrates should be blasted to SSPC-SP-6 minimum, with a 1 mil blast profile, and primed with a good quality alkyd primer (such as Pruett-Schaffer #30-12620). This coating is very tolerant of less than perfect surface preparation, so hand tool cleaning may be sufficient for some uses. At a minimum for acceptable performance, surfaces to be coated must be clean and dry, and free of oil/grease, loose rust/paint, weld spatter, burning slag, dust, and chalk. Feather all rough or sharp edges. Chalky or dusty surfaces should be		power washed and allowed to dry completely. THINNING Under normal conditions no thinning is necessary. Thin if necessary for spraying with xylol or toluol. Add a little at a time with constant gentle agitation to a maximum of 5% by volume. In ambient temperatures over 85 ⁰F Aromatic 100 or Aromatic 150 may be used if "dry spraying" occurs. APPLICATION EQUIPMENT May be applied by brush or airless spray. Airless spray gives the best results, use .015-.020 inch tip size. Brushes should be of polyester or nylon construction. If applying with a cup type spray gun, thinning may improve application. Apply to 2-4 mils dry film thickness, or 4.5-8.0 mils wet film. DRYING TIME Dries to recoat or stencil in 1 to 2 hours at 77 ⁰F. Dry to light handling in 24 hours. Force drying ovens may be used, allow 30 minutes minimum for flashoff of solvent before heating. CLEANUP Clean equipment with xylol or toluol before the film dries. ENVIRONMENTAL This product meets current air pollution regulations regarding hydrocarbon and ozone reactive emissions. It is VOC compliant for the railcar and architectural maintenance industries, and contains no lead or chromate.
