TECHNICAL DATA

SURFACE PREPARATION

PC7 Topcoat is designed as a finish coat over properly prepared and primed substrates including steel, aluminum, galvanized steel, concrete, masonry, MDF, drywall, interior wood and previously coated surfaces. Substrates should be primed with DTM 1300 modified epoxy sanding primer, DTM 1600 single component bonding primer or DTM 3000 two component polyurethane primer: PC7 is not recommended for floors

Steel – Clean the surface to ensure that the substrate is free of grease, dirt, wax, mildew and other contaminates (SSPC-SP1) and abrade to achieve SSPC-SP2, SP3, SP6, SP7 or SP11 levels of surface preparation. Precision’s 02150 Metal Conditioner may be used to clean and treat steel substrates to eliminate oil, soap film, grease and flash rusting.

Aluminum & Galvanized Steel – Clean the surface to ensure that the substrate is free of grease, dirt, wax, mildew and other contaminates SSPC-SP1. Utilize SSPC- SP 16 sweep blast for aluminum or galvanized steel or 02150 Metal Conditioner or comparable phosphoric acid conditioner to remove preservatives and prepare the surface for coatings.

Concrete, Masonry, MDF, Drywall – Surface must be clean, dry and free of any dirt, dust, grease, oil, wax, mildew, disintegrated or chalky materials or other contaminants.

Previously Coated Surfaces – Surface must be clean, dry, and free of any dirt, dust, grease, oil, wax, mildew, disintegrated or chalky materials or other contaminants. Aged coatings should be abraded to achieve an acceptable profile to provide adequate adhesion for the primer and topcoat.

INSTRUCTIONS

Stir or shake each container before mixing together. Mix thoroughly 16 parts PC7 Waterborne Polyurethane Topcoat with 1 part of PC-07 Activator. Accurate measurement is essential. Reduction is not necessary, however, coating may be reduced up to 5% by volume using tap water. Note: do not use any mixed PC7 after 2 hours and clean application tools and material containers before reuse.

APPLICATION FOR “SOLID COLORS” & “METALLIC COLORS”

Environmental Conditions: Air and surface temperature must be above 50⁰ Fahrenheit and no more than 90⁰ Fahrenheit. Surface temperature must be at least 5⁰F (3⁰C) above the dew point

Application: Solid colors may be applied by spray, roller and brush application. Metallic colors should be applied by spray application only. Allow a 5 to 10 minute flash time between coats if spray applied. PC7 should be applied to achieve a recommended dry film thickness between 1.0 to 3.0 mils. For detailed metallic and iridescent application instructions, see Precision Coatings’ Guidance: “Metallic and Iridescent Finishes.”
