ABSTRACT:
The water resistance exhibited during the curing of certain moisture curable RTV polyorganosiloxane compositions containing calcium carbonate fillers is significantly increased by treating the calcium carbonate with a hydrophobicizing agent selected from cationic surfactants, nonionic surfactants having HLB values of 10 or less, and organosilanes.
