ABSTRACT:
An improved gel coat for integral molded products having increased hardness consists of a synthetic resin mixed with tabular alumina and a surface treating agent such as gamma-Methacryloxypropyltrimethoxysilane. The gel coat may be applied as a first layer over a mold, pattern, part, or other surface with a filler reinforced resin layer applied to the first layer or with an intermediate layer of resin filled with calcium silicate applied between the gel coat and the reinforced layer. The gel coat may also be used as a surface coating for steel, composite, and concrete structures.
