PAINT RESIN FOR USE IN PARAFFINIC SOLVENTS

摘要

This invention discloses a resin which is particularly useful in making paraffinic solvent based paints, said resin being comprised of repeat units which are derived from (a) about 10 to about 55 weight percent para-tertiary-butyl styrene, (b) 0 to about 40 weight percent vinyl aromatic monomers, (c) about 20 to about 80 weight percent alkyl methacrylate monomers, and (d) about 2 to about 25 weight percent alkyl acrylate monomers. These resins exhibit good hardness and improved resistance to ultraviolet light. The subject invention further discloses a paint formulation which is comprised of (a) a paraffinic solvent; (b) a resin which is comprised of repeat units which are derived from (i) about 10 to about 55 weight percent para-tertiary-butyl styrene, (ii) 0 to about 40 weight percent vinyl aromatic monomers, (iii) about 20 to about 80 weight percent alkyl methacrylate monomers, and (iv) about 2 to about 25 weight percent alkyl acrylate monomers; and (c) one or more pigments.
