Aluminum Alkyd Paint, Leafing (Type I) and Non-Leafing (Type II)
This specification covers two types of aluminum alkyd paint for steel. Both have good weathering in rural, industrial, and marine atmospheres. They are also excellent paints for interiors. These paints are not intended for use over bare steel. These paints are suitable for exposures in Environmental Zones 1A (interior, normally dry) and 1B (exterior, normally dry) and are intended for brush or spray application over rust inhibitive priming paints, over themselves, or over other oleoresinous paints. Each paint is suitable as an intermediate or topcoat and is to be applied in accordance with SSPC PA 1, Shop, Field, and Maintenance Painting of Steel. Two types are available under this specification. Type I covers a leafing aluminum paint intended as a finish paint and Type II covers a non-leafing aluminum paint intended as an intermediate coat to provide contrast with the Type I finish coat.
