The present invention is based on the discovery that concentration levels of {HEAD ~ copper acetylacetonate} considered ineffective by the prior art will effectively retard thermally induced hardening of {TAIL ~ fluorosilicone gels} prepared by a hydrosilylation reaction using curable compositions containing an N,N,N,N tetraalkyl alkylenediamine as a catalyst inhibitor
