TIN CATALYST MADE OF TIN NOXIDE AND BETA-DICARBONYL COMPOUNDS FOR SILICONE ELASTOMER COMPOSITIONS.

摘要

Organopolysiloxane compositions curable into elastomeric state, whether in single- or two-component form, comprise an alpha , omega -dihydroxypolydiorganopolysiloxane oil, a crosslinking agent therefor, optionally, inorganic fillers and an adhesion promoter, and a catalytically effective amount of a pentacoordinated tin monochelate produced by reacting a tin oxide with a beta -dicarbonyl compound and a carboxylic acid.
