B. Aluminum (General Aviation Aircraft, truck bodies and misc) Apply DX 533 Aluminum Cleaner. Rinse with water. Condition surface with DX 503 Aluminum Conditioner. Rinse with water. Dry and apply DP Epoxy Primer/401 Catalyst and DURETHANE® topcoat color. C. Cold rolled steel or steel plate (with little or no rust or mil scale). Treat surface with DX 579 Metal Cleaner. Rinse with water. Apply DX 520 Metal Conditioner. Rinse with water. Dry and apply DP Epoxy Primer/401 Catalyst and DURETHANE topcoat color. D. Cold Rolled Steel or Steel Plate (with heavy rusting or mil scale). Sand blast surface to gray metal. Blow off dust with clean compressed air. Clean with ACRYLI-CLEAN® Wax and Grease Remover (DX 330). Apply DP Epoxy Primer/401 Catalyst and DURETHANE topcoat color. E. Old DURETHANE, Epoxy, or other catalyzed finishes. Wash with ACRYLI-CLEAN Wax and Grease Remover (DX 330). Sand thoroughly with 220 grit or finer DA or 320-400 wet or dry. Reclean surfaces. Apply DURETHANE Primer (DPU 35/301) or DP Epoxy Primer/401 Catalyst, then topcoat with DURETHANE color. F. Fiberglass. New molded parts should be washed with a clean cloth liberally soaked with alcohol. Dry with clean white cloths. Wash thoroughly with ACRYLI-CLEAN Wax and Grease Remover (DX 330). Lightly sand to remove all gloss with 320 grit or finer. Avoid sanding through gelcoat - make sure fiberglass strands are not showing. Reclean surface. Apply DP Epoxy Primer/401 Catalyst and DURETHANE topcoat color. Mixing: Mix DU Colors thoroughly with the appropriate DT Reducer and DU Hardener best suited for shop conditions using the following ratios: DU 5 or DU 6 DU Color DT Reducer Hardener Solid Colors 1 gallon 2-3 quarts 1 gallon Metallic Colors 1 gallon 3-4 quarts 1 gallon Application and Dry Times: ×Set air pressure for 45 - 50 lbs. at the gun when using a siphon feed gun. ×Apply 2-3 full wet coats. ×Allow 15 to 20 minutes tack time between coats. ×Allow the final coat to air dry at normal temperature (75°F/24°C) for 16 hours or force dry for 50 minutes @ 160°F (71°C). 2 Form P-138 (9/90)
Application of Second Color (Two-Toning): If a second color is to be applied, allow the first color to air dry a minimum of 8 hours at normal conditions (75°F/24°C) before taping. Tape time may be reduced to approximately 4 hours with the use of DXR 81 Accelerator additive in the first color at the rate of 1 fluid ounce per gallon of ready to spray DURETHANE® Color. Caution! This will also reduce the sprayable pot life to 4 hours at normal temperature of 75°F (24°C). Clearcoating (DU 1000): For an extra high gloss glamour appearance, DURETHANE colors may be clearcoated with DU 1000 clear topcoat. Allow the DU solid color to dry a minimum of 20 minutes and DU metallic colors to dry a minimum of 2 hours, but no longer than 1 week before applying DU 1000 Clearcoat. Mix one part DU 1000 with ½ part of DT Reducer and 1 part DU 5 or DU 6 Hardener (1:½:1). Apply two full wet coats using 50 PSI at the gun with approximately 30 minutes tack time between coats but within 2 hours. If tack time exceeds two hours, allow the final coat to dry overnight. Example: Recoating: DU 1000 DT Reducer DU 5 or DU 6 1 part ½ part 1 part or or or 4 quarts 2 quarts 4 quarts DURETHANE may be recoated with itself after curing for a minimum of 8 hours @ 75°F (24°C) or a maximum of 1 week. After 1 week, scuff sand with 320 - 400 wet or dry, reclean with DX 330, and reapply DU Color. Flexible Substrates: No flexible additive is necessary when applying DURETHANE Color over most flexible substrates. Additives: DX 77 Fisheye Preventor: Surfaces to be painted must be thoroughly cleaned and prepared. The use of DX 77 is not recommended unless absolutely necessary. Flowout is decreased in direct proportion to the amount of preventor used. When necessary, DX 77 may be used in a ratio of 1 to 2 screw capfuls per sprayable quart of DU Color. DXR 81 Accelerator: Accelerators are used to speed up the tape and dry times or to help when two-toning. The dry time of DU Color may be accelerated with DXR 81 by using up to ½ ounce per sprayable quart or 2 ounces per sprayable gallon. 3 Form P-138 (9/90)
