Silicone coated fabric
First Claim
1. A method for making a translucent, weather-resistant, fire-retardant, silcone coated woven fabric substrate comprising the steps of:
- (a) applying a high tear strength composition comprising a first translucent silicone liquid elastomer and aluminum hydroxide, to a clean, woven, translucent substrate;
(b) allowing the first silicone liquid elastomer to penetrate the substrate and thereby form a translucent base coating on the translucent substrate;
(c) passing the translucent base coated substrate through first fashioning means for controlling the thickness of the base coating;
(d) allowing the base coating to cure;
(e) applying a second translucent silicone liquid elastomer to the cured translucent base coated substrate thereby forming a translucent top coating, said second silicone liquid elastomer being applied at a temperature of less than about 150°
F.;
(f) passing the top coated substrate resulting from step (e) through second fashioning means for controlling the thickness of the top coating; and
(g) curing the top coating, whereby, a translucent, fire retardant, woven fabric substrate is produced.

Abstract
The present invention is directed to method for making silconecoated woven fabric substrates, and the products produced by such method. The method comprises the steps of applying a first liquid polysilicane elastomer to the substrate so as to form a base coat, curing the base coat, applying a second liquid polysilicane elastomer over the base coat so as to form a top coat, and curing the top coat. By specifically selecting the polysilicane elastomers as well as the substrate, and by further selecting the reaction parameters, a high strength, non-flammable, waterproof, self-cleaning, translucent and weather-resistant fabric is produced.
