Curable compositions
Abstract
Abstract FLUID ORGANOPOLYSILOXANE WHICH ARE VULCANIZABLE AT ROOM TEMPERAURE TO SILICONE ELASTOMERS ARE PREPARED BY MIXING A NOVEL CO-CATALYST SUCH AS A MIXTURE OF DIBUTYL TIN DIMETHOXIDE AND PROPANEDIOXY BIS(ETHYLACETOACETATE COMPLEX TO TITANIUM A CROSS-LINKING AGENT SUCH AS METHYL)TRIMETHOXYSILANE AND A SILANOL CHAIN-STOPPED POLYDIORGANOSILOXANE FLUID IN THE ABSENCE OF MOISTURE. VISCOSITY DEPRESSANTS SUCH AS LOW MOLECULAR WEIGHT POLYSILOXANE DIOLS AND ADHESION PROMOTERS SUCH AS 1,3,5-TRIS(TRIMETHOXYSILYLPROPYL)ISOCYANURATE MAY OPTIONALLY BE PRESENT THESE COMPOSITIONS ARE STABLE, FREE-FLOWING FLUIDS IN THE ABSENCE OF MOISTURE BUT CURE TO THE RUBBERY SOLID ELASTIC STATE UPON EXPOSURE TO MOISTURE. THE COMPOSITIONS ARE PARTICULARLY USEFUL AS ADHESIVE AND SEALANTS IN THE CONSTRUCTION OF ELECTRONIC EQUIPMENT IN THAT THEY DO NOT GIVE OFF CORROSIVE BY-PRODUCTS WHEN CURING. THEY ARE ALSO USEUL IN THE FORMATION OF ORTHOPEDIC DEVICES CAST ON THE HUMAN FOOT.
