Curable compositions
Abstract
Abstract FLUID ORGANOPOLYSILOXANES WHICH ARE VULCANIZABLE AT ROOM TEMPERATURE TO SILCONE ELASTOMERS ARE PREPARED BY MIXING A NOVEL TITANIUM CATALYST SUCH AS THE PROPANEDIOXY BIS(EHTYLACETONACETONATE) COMPLEX OF TITANIUM, A CROSS-LINKING AGENT SUCH AS METHYLTRIMETHOXYSILANE AND A SILANOL CHAIN-STOPPED POLYDIORANOSILOXANE FLUID HAVING A VISOCITY OF 1,000 TO ABOUT 10,000 CENTIPOIES AT 25*C. IN THE ABSENCE OF MOISTURE. 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 ASHESIVES AND SEALANTS IN THE CONSTRUCTION OF ELECTRONIC EQUIPMENT IN THAT THEY DO NOT GIVE OFF CORROSIVE BY-PRODUCTS WHEN CURING.
