Reinforced resin filler compositions

摘要

Reinforced synthetic polyester resin compositions are provided having 10 to 60 percent by weight of resin, 1 to 30 percent by weight of glass spheres, 10 to 60 percent by weight of Suzorite mica platelets, and 20 to 70 percent by weight of aluminum trihydrate particles. The compositions may be applied to a mold or to a plastic sheet. They do not require glass fibers, and thus avoid the laborious rolling down of fibers carried on the surface of freshly applied glass fiber-resin compositions. Yet, articles formed from the compositions of the invention retain or improve upon the physical properties inherent in glass fiber-resin compositions.
