ABSTRACT:
Concentration levels of copper acetylacetonate previously considered ineffective inhibit or eliminate thermally induced hardening of fluorosilicone gels prepared by a hydrosilylation reaction using one-part curable compositions containing an N,N,N',N'-tetraalkyl alkylenediamine as a catalyst inhibitor. This inhibitor can be used alone or in combination with acetylenic alcohols such as methylbutynol to modify the curing characteristics of the composition and/or the properties of the cured gel.
