This specification covers a ready mixed white vinyl chloride-acetate copolymer paint intended for use as a primer over blast cleaned steel or over vinyl butyral wash primer (SSPC Paint 27*). It may also be used as an intermediate or finish coat over vinyl chloride-acetate copolymer paint.
This paint is suitable for exposures in Environmental Zones 2C (fresh water immersion), 2D (salt water immersion), 3A (chemical, acidic), and 3B (chemical, neutral), and is intended primarily to be used 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 allows for a choice of colors.
This paint consists of titanium dioxide pigment and vinyl resins in solution suitably plasticized to make a durable, elastic paint film. This paint includes both a carboxylcontaining polymer for good adhesion to steel and a hydroxyl-containing polymer for good adhesion to wash primers. It is supplied, unless specified otherwise, as a white paint.
This paint contains approximately 17% 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 275 square feet/U.S. gallon (6.7 square meters/liter). Actual spreading rates can be significantly lower.
