Abstract
Abstract The coating composition is useful for reparing the finish of flexible automobile and truck bumpers and comprises a blend of the following polymers: 1. A COPOLYMER OF METHYL METHACRYLATE AND AN ALKYL ACRYLATE OR AN ALKYL METHACRYLATE HAVING 2-12 CARBON ATOMS IN THE ALKYL GROUPS; 2. A COPOLYMER OF METHYL METHACRYLATE AND AN ADHESION OF PROMOTING MONOMER SUCH AS THE 3-2-METHACRYLOXYETHYL (-2,2 SPIRO CYCLOHEXYL OXAZOLIDINE); 3. A PLASTICIZER WHICH IS EITHER A PHTHALATE ESTER SUCH AS BUTYL BENZYL PHTHALATE OR BUTYL CYCLOHEXYL PHTHALATE OR AN ALKYD RESIN; THE NOVEL COMPOSITION CAN BE BLENDED WITH OTHER PIGMENTED ACRYLIC POLYMER COATING COMPOSITIONS TO FORM A HIGH QUALITY REFINISH COMPOSITION FOR FLEXIBLE BUMPERS.
