Abstract
A light anti-chipping coating consisting of vinyl chloride plastic sol is manufactured by employing a hollow filler as a small portion of the overall filler component. Doing so permits weight reduction without deteriorating the anti-chipping property of the light anti-chipping coating.
Claims6
A light, anti-chipping coating consisting essentially of a blend of 100 parts by weight of a polyvinyl resin capable of forming a plastisol, 50 to 200 parts by weight of a plasticizer for said resin, 2 to 20 parts by weight of additives and 80 to 350 parts by weight of a filler component, said filler component consisting of from 0.5 to 5% by weight of expanded thermoplastic microspheres and the balance being solid calcium carbonate filler powder.
A light, anti-chipping coating consisting essentially of a blend of 100 parts by weight of a polyvinyl resin capable of forming a plastisol, from 50 to 200 parts by weight of a plasticizer for said resin, from 2 to 20 parts by weight of additives and 80 to 350 parts by weight of filler component, said filler component consisting of from 0.5 to 5% by weight, based on the weight of said filler component, of vinylidene chloride/acrylonitrile copolymer, hollow, filler particles and the balance being solid calcium carbonate filler powder.
A light, anti-chipping coating consisting essentially of a blend of 100 parts by weight of a polyvinyl chloride resin capable of forming a plastisol, 50 to 200 parts by weight of a plasticizer for said resin, 2 to 20 parts by weight of additives and from 80 to 350 parts by weight of filler component, said filler component consisting of (1) a member selected from the group consisting for from 1 to 9% by weight of glass or silica, hollow, filler particles, from 0.5 to 5% by weight of vinylidene chloride/acrylonitrile copolymer, hollow, hollow, filler particles, and from 0.5% to 9% by weight of glass or silica and vinylidene chloride/acrylonitrile copolymer, hollow, filler particles, said weight of said filler particles being based on the weight of said filler component, and (2) the balance being solid calcium carbonate filler powder.
