Key Universal Primer
KEY UNIVERSAL PRIMER is a one component, moisture cured polyurethane coating. Key Universal Primer has excellent adhesion to sound, tightly adhered rusty steel, other marginal or poorly prepared metal surfaces, and properly prepared concrete. Its low viscosity, high "wetting" characteristics, creep, undercutting, and blistering resistance make Key Universal Primer a superior primer and finish coat for steel. Key Universal Primer can also be used as a primer when installing Key Vinyl Ester Systems or Key MMA Systems in certain applications, contact Key Resin for recommendations.
