Polydimethylsiloxanes having improved thermal stability.

摘要

Silicone compositions having improved thermal oxidative stability are disclosed. The compositions contain iron acetylacetonate, nickel acetylacetonate, cerium acetylacetonate, alpha,omega-bis(trimethylsiloxy)-polydimethylsiloxanes, and optionally, a carboxylic acid. The compositions show greatly increased gel times at temperatures of, e.g. 275 DEG C.
