Zusammenfassung:The water permeability of cured thermosetting organic resin compositions is reduced and the dimensional stability of these compositions during molding is improved by the addition to the curable resin composition of a finely divided, cured organosiloxane material prepared from a curable organopolysiloxane, a curing agent for the organopolysiloxane, an optional silica filler and an aromatic hydrocarbon compound containing a substituted benzene ring where the substituent is a monovalent ethylenically unsaturated hydrocarbon radical or an alkenyloxy radical.
