Rustoleum - 4268 Heat Resistant Primer is a Anti-corrosive heat resistant metal primer for new, bare steel or blasted steel surfaces that provides heat resistance up to 425°C dry heat.
Rustoleum - 4268 Heat Resistant Primer is a Anti-corrosive heat resistant metal primer for new, bare steel or blasted steel surfaces that provides heat resistance up to 425°C dry heat.
Features
Recommended Use
Rustoleum 4268 should be used on new, bare steel or blasted steel surfaces and provides heat resistance up to 425°C dry heat in sheltered or interior environments, if recoated with Heat Resistant Topcoat 4215. On blasted steel two coats of Primer 4268 should be applied prior to the application of 4215.
Surface Preperation
Remove grease, oil and all other surface contaminations by alkaline- or high pressure (steam) cleaning in combination with appropriate detergents. For optimum results remove rust, rust scale, mill scale and deteriorated coatings by abrasive blasting to Sa 2½ (ISO 8501-1 : 1988), blast profile max. 50 µm. The surface must be clean and dry during application.
Directions For Use
To ensure homogeneity, coating materials should be thoroughly stirred prior to use.
Application Conditions
Temperature of air, substrate and coating material between 5 and 35°C and relative humidity below85%. The substrate temperature must be at least 3°C above dewpoint.
