ABSTRACT:
Novel organotin curing catalysts for, e.g., the RTV organopolysiloxanes, whether single- or two-component such compositions, are comprised of admixture of (i) a diorganotin bis(.beta.-diketonate) and (ii) an organotin (IV) compound devoid of .beta.-diketonato functional group. The silicone elastomers produced thereby are notably well adopted for use in the building industry.
