ABSTRACT:
Method of preparing superior scratch resistant coatings which are particularly well suited for use in combination with unsaturated polyester gel coats in applications where a smooth, high gloss, durable, scratch resistant surface is desirable, such as in marine and cultured marble applications, include compositions comprising at least one polyfunctional monomer having 3 or more acryloloxy groups per molecule, preferably 5 or more acryloloxy groups, and either at least one N-vinyl imido group containing monomer or at least one polyallylglycidyl ether containing compound. These coating compositions are cured either by exposure to ultraviolet radiation or by thermal means, preferably using organic peroxides.
