Abstract
Translucent polyorganosiloxane resin compositions exhibiting acceptable levels of flame retardancy contain from 1 to 10%, based on resin weight, of an organic halogen source in combination with finely divided glass particles. Translucent substrates coated with these resin compositions can be used in the exterior portions of buildings intended to be heated at least in part by solar energy.
Claims13
In an article of manufacture comprising a translucent fibrous substrate and a translucent coating on said substrate, said coating consisting essentially of a polyorganosiloxane resin and an effective amount of a flame retardant for said resin, the improvement comprising the presence in said resin of a flame retardant consisting essentially of from 1 to 10 parts by weight per 100 parts of said resin of an organic compound containing at least one halogen atom, selected from the group consisting of bromine and chlorine and from 5 to 150 parts by weight per 100 parts of said resin of glass particles having an average particle size of from 5 to 100 microns;
- the weight ratio of said organic compound to the glass particles being from 0.05 to 0.4.
