scope:

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 (saltwater 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 under-coats, 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."
