Low pressure molding compositions

摘要

Improved low pressure molding compositions are disclosed which comprise an unsaturated thermosetting resin, an olefinically unsaturated monomer copolymerizable with the thermosetting resin, a viscosity reducing additive, a thermoplastic additive and a thickener comprising one or more alkaline earth metal oxides or hydroxides which can provide the molding compositions with viscosities of less than 25 MMcps after aging.
