Abstract
Improved, curable resin compositions are provided for use as and for surface coatings, flooring, structural fabricated parts, cast parts, dry lubricants and as dry filler for other resin systems, to reduce surface friction. The resin compositions comprise an unsaturated polyester type resin or an epoxy type resin, a filler paste consisting of dimethyl silicone, polytetrafluoroethylene, polyethylene and ouricury wax and a color pigment. For use outdoors, the compositions contain, additionally, an ultraviolet light stabilizer. Compositions for use as conditioners and cleansers for the surfaces are also provided.
Claims11
A curable resin surface coating composition comprising:
- (a) about 50-90% by weight of a resin selected from the group consisting of curable unsaturated polyester resins in styrene solution and epoxy-type resins;
- (b) about 10-60% by weight of a filler paste mixture consisting of dimethyl silicone, polytetrafluorethylene, polyethylene and ouricury wax;
- and
- (c) about 2 to 6% by weight of a color pigment.
A composition according to clam 5 wherein said ultraviolet light stabilizers are selected from a group consisting of 2,4-dihydroxy-benzophenone, 2-hydroxy-4-methoxy-benzophenone, 4-dodecyloxy-2-hydroxy-benzophenone, 2-(2'-hydroxy-5'-methyl phenyl) benzotriazole, 2-(3',5'-di-tert-butyl-2'-hydroxy phenyl)-5-chlorobenzotriazole, 2-(3'-tert-butyl-2'-hydroxy-5'-methyl phenyl)-5-chlorobenzotriazole, phenyl salicylate, 2-octyl-2-cyano-3,3-diphenyl acrylate and ethyl-2-cyano-3,3-diphenyl acrylate.
