Abstract: A condensation cure organosiloxane composition is disclosed. The composition may be used as an electrically insulating sealant and/or adhesive. The composition comprises: (a) a polydiorganosiloxane having at least two —OH or hydrolysable groups per molecule; (b) a cross-linker which will cross-link polydiorganosiloxane (a); (c) a filler component comprising calcium carbonate; (d) a filler treating agent comprising one or more carboxylated liquid organic polymers; (e) a condensation curing catalyst; and optionally (f) one or more additives. Upon cure, the composition provides a silicone elastomer having a volume resistivity which is ≥2×1015 Ω·cm.
