Abstract:

A reaction mechanism is provided for formation and utilization of silicone-titanium copolymer H. The use of heated air on the rain spray apparatus did not result in increased durability of formulations containing silicone-titanium copolymer H. A new rain spray apparatus is under construction which is designed to deliver a more uniform rain spray and allow the use of larger test panels. In the preparation of silicone-zirconium copolymers reaction at a temperature of 138-140 C. results in a clear liquid yielding a dry, waxy film, whereas reaction at 105 C. results in a cloudy liquid giving a soft and tacky film.
