GENERAL DESCRIPTION Pruett-Schaffer’s #30-664 Red Univer-sal Primer is a solvent-based, high solids, rust inhibitive primer paint intended for application over steel surfaces. It is designed to be brush or roller applied, but spray application is the preferred method. This primer serves as a cost-effective universal primer or tie coat, having good application properties requiring minimal surface preparation. RECOMMENDED USES This product is recommended for general maintenance use on steel substrates wherever a good quality universal alkyd primer is needed. It may be topcoated with water or solvent based alkyds, acrylics, vinyls, epoxies, or urethanes. It exhibits good early hardness development, and excellent water, salt, hydrocarbon solvent, and lacquer resistance. This primer is specially recommended for use over surfaces where extensive preparation will not be performed, as the alkyd formulation of this paint wets rusty and oily substrates efficiently and develops good adhesion. The in-service temperature limit is approximately 300 ^0F. This product is not recommended for water immersion service or for use over wood or other dimensionally variable substrates. Although this paint exhibits good chemical resistance in normal industrial environments, it is not recommended for severe chemical exposures.

SURFACE PREPARATION For best results, substrates should be blasted to SSPC-SP-6 commercial blast with a 1 mil profile, and all rough areas and sharp edges smoothed. This coating is tolerant of less than perfect surface preparation however, and hand or power tool preparation such as brushing, sanding or water blasting may be sufficient for many applications. At a minimum for acceptable performance, surfaces to be coated must be clean, dry, free of heavy oil and grease, loose rust and paint, weld spatter, burning slag, dust, and chalk. THINNING Under normal conditions, no thinning is necessary. When required for proper spraying, thin with TT-T-306c Thinner. Add a little at a time with constant gentle agitation to a maximum of 20% by volume. APPLICATION EQUIPMENT May be applied by brush, roller, or airless spray equipment. Airless spray gives the best results, use .015-.020 inch tip size. Brushes should be of polyester or nylon construction. Apply to a dry film thickness of 0.9-1.1 mils. DRYING TIME Dry tack free in 10-20 minutes, dry to light handling in 45 minutes, dry to recoat in 4 hours at 77 ^0F. Force drying ovens may be used; allow 15 minutes minimum for flashoff of solvent before heating.

CLEANUP Clean equipment with xylol or toluol before the film dries.
