Abstract
The addition of up to 40 percent by weight of a non-reactive liquid MQ resin to high viscosity liquid curable organosiloxane compositions that cure by a platinum group metal-catalyzed hydrosilation reaction reduces the viscosity of the composition and the moduli of cured elastomers prepared from said composition without any substantial adverse effect on the physical properties of the cured elastomers, particularly tensile strength, elongation and tear strength. Cured elastomers prepared using these compositions are particularly suitable for use as mold-making and encapsulating materials.
