Abstract
Abstract A METHOD OF CURING A ROOM TEMPERATURE VULCANIZABLE SILICON COMPOSITION TO OTHER CURED SILICONE RUBBERS BY APPLYING A METAL CARBOXYLATE TO THE SURFACE OF THE CURED SILICONE RUBBER PRIOR TO APPLYING THE ROOM TEMPERATURE VULCANIZABLE SILICONE COMPOSITION IS DISCLOSED. THE ROOM TEMPERATURE VULCANIZABLE SILICONE COMPOSITION IS A MIXTURE OF A HYDROXYLATED ORGANOSILOXANE POLYMER, A HYDROCARBONOXY SILICON COMPOUND OR A SILICON COMPOUND HAVING SILICON BONDED HYDROGEN ATOMS, AND A CURING CATALYST. THE METAL CARBOXYLATE CAN BE ILLUSTRATED BY DIBUTYLTINDILAURATE. THIS METHOD IS USEFUL IN SEALING, ENCAPSULATING AND BONDING PROCESSES WHERE SOME OR ALL THE PARTS ARE CURED SILICONE RUBBER.
