Organopolysiloxane compositions hardening into translucent elastomers at room temperature in the presence of humidity

摘要: The invention concerns organopolysiloxane compositions obtainable by the following successive steps: step 1: reacting (i) at least a linear diorganopolysiloxane reagent A comprising hydroxyl group each chain end; (2i) and resin B having weight content of ranging from 0.1 to 10%; (3i) with polyalkoxysilane C; 2: introducing in medium 1 (6i) mineral filler G based on amorphous silica (7i) an efficient amount catalyst H consisting one titanium organic derivative; 3: resulting mixture is subjected devolatilization carried out pressure less than atmospheric pressure.
