This specification covers a ready-to-mix aluminum vinyl chloride, acetate copolymer paint intended for use over vinyl butyral wash primer (SSPC-Paint 27) or as a finish coat over vinyl chloride-acetate copolymer paint such as SSPC-Paint 9. This paint is not intended or recommended for use over bare steel.
This paint is suitable for exposures in Environmental Zones 2C (fresh water immersion), 2D (salt water immersion), and 3B (chemical, neutral), and is intended primarily to be used as a finish coat in a system applied to blast cleaned (SSPC-SP 10) or pickled (SSPC-SP 8) steel. When used for salt water immersion, a wash primer is recommended. Because of the possibility of lifting of the undercoats,
this paint is not intended to be used over types of paints which have poor solvent resistance. This paint is intended primarily for application by conventional air spray and is to be applied in accordance with SSPC-PA 1, “Shop, Field, and Maintenance Painting of Steel.”
This paint consists of metallic leafing aluminum pigment and vinyl resins in solution suitably plasticized to make a durable, elastic paint film. This paint includes a hydroxyl-containing polymer for good adhesion to wash primers. It is supplied, unless specified otherwise, as two components to be mixed just before use.
2.2 This paint contains approximately 14% by volume of nonvolatile film-forming solids (pigment and binder). The theoretical spreading rate for a 1.0 mil (25 micrometers) dry film thickness is 225 square feet/U.S. gallon (5.5 square meters/liter). Actual spreading rates can be significantly lower.
