NEW GENERAL ELECTRIC BONDING AGENTS FOR SILICONE RUBBER MAKE A BOND S T R O N G E R T H A N THE RUBBER ITSELF!
New bonding agents for silicone rubber, recently developed by General Electric chemists, are expected to greatly increase the usefulness of silicone rubber in structural combinations with metal, glass, ceramics and other materials. The new primer and adhesives make possible a bond between silicone rubber and almost any material which is stronger than the silicone rubber itself. These bonding agents have the same remarkable resistance to temperature extremes that silicone rubber itself has, successfully withstanding temperatures from —85 F to 500 F. Typical applications include the mounting of engines and instruments on silicone rubber to reduce vibration and shock.
G-E CHEMICAL BREVITIES A new coating intermediate, General Electric's R-108. is opening up new business opportunities to the paint and finishes industry. Ordinary steel, finished with coatings containing R- 108, can often be substituted for expensive or scarce alloys. Longer motor life is provided by the use of G-E varnished cloths and t a p e s , part of G .
