One-part heat-curable silicone elastomer composition comprises an ethylenically or acetylenically unsaturated polyorganosiloxane, a hydrogen-functional polyorganosiloxane, a metal catalyst, a filler, an adhesion promoter, a silicone resin, a heat stabilizer, and a crosslinking inhibitor selected from bisphosphonite esters (I) and phosphite esters (II). One-part heat-curable silicone elastomer composition comprises an ethylenically or acetylenically unsaturated polyorganosiloxane, a hydrogen-functional polyorganosiloxane, a metal catalyst, a filler, an adhesion promoter, a silicone resin, a heat stabilizer, and a crosslinking inhibitor selected from bisphosphonite esters of formula (I) and phosphite esters of formula (II). R, R1-R4, R1'-R3' = (cyclo)alkyl or optionally substituted aryl. Independent claims are also included for: (1) production of the composition by preparing a catalyst component by mixing the inhibitor with a solution or dispersion of the catalyst or by mixing the catalyst with a dispersion of the inhibitor in silicone oil; mixing some of the ingredients except for the catalyst component; heating and cooling the mixture; adding the rest of the ingredients except for the catalyst component, and then adding the catalyst component; and (2) adhesive comprising the composition. |
