Abstract
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 bischelate with an organic carboxylic acid.
