ABSTRACT:
Coating compositions comprising a blend of nitrocellulose and a copolymer of 6 to 32 percent by weight ethylene, 36 to 65 percent by weight vinyl chloride and 23 to 50 percent by weight vinyl acetate in a solvent system, the ratio of nitrocellulose to copolymer being 80:20 to 20:80. Modifying resins, e.g., sucrose benzoate, maleic acid resin, etc.; and plasticizers, e.g., tris 2,3-dibromopropyl phosphate, di(2-ethylhexyl) phthalate, etc., can be present in the compositions. The coatings possess excellent adhesion to various substrates as well as excellent hardness, toughness, low temperature flexibility and low flammability.
