Abstract: A transparent and fast curing composition suitable for use as a shatter-resistant coating on a glass, porcelain, or ceramic surface, wherein the composition comprises:(A). at least about 62 to about 71 parts by weight of a solid, benzene soluble resin copolymer consisting essentially of R.sub.3 SiO.sub.1/2 units and SiO.sub.4/2 units,(B). from about 29 to about 38 parts by weight of an essentially cyclic free, polydiorganosiloxane, the viscosity of the polydiorganosiloxane having a value of from about 500 to about 1,000,000 centipoises at 25.degree. C., the total of (A) and (B) being 100 parts by weight;(C). an organopolysiloxane having silicon bonded hydrogen atoms,(D). a platinum containing catalyst in sufficient quantity to provide at least 0.1 part by weight of platinum for every one million parts by weight of the combined weight of (a), (b), and (c).The composition forms a coating which is transparent, fast curing, and stable at elevated temperatures.
