Abstract
Organopolysiloxane compositions readily cross-linked into elastomers, e.g., elastomeric seals, and advantageously formulated in either one- or two-component packages, are comprised of (A) a polyhydroxylated polysiloxane, (B) a polyacyloxysilane cross-linking agent and (C) a hardening accelerator therefor, said hardening accelerator being protectively microencapsulated within impermeable outer skin membranes adopted to be chemically or physically disrupted, e.g., by heat, irradiation or mechanical breaking, to permit the release of said accelerator (C) therefrom and consequent curing of the composition.
