Abstract
Curable organosiloxane compositions that cure by a platinum group metal catalyzed hydrosilation reaction to yield machinable elastomers exhibiting a high resistance to erosion contain an alkenyl-functional organosiloxane copolymer as the reinforcing agent together with quartz and organic or inorganic microspheres as the non-reinforcing filler. The concentration and density of the microspheres are preferably within specified limits.
