  • Method of making molding compounds and materials made thereby
    Patent number: 4105623
    Abstract: A method of making molding compounds and particularly sheet molding compounds in which a novolak is dispersed throughout an inorganic filler and a slight reaction is caused to take insitu with a hydrogen donor that is preferably hexamethylenetetramine to produce a molding compound. In the case of a sheet molding compound, the material is spread out into a thin sheet and inorganic fibers are embedded therein, following which a body-building reaction is initiated to liberate some ammonia. Thereafter, the material is dried and solidified into a solid handleable sheet molding compound.There is also disclosed a method for forming the novolak resin insitu by reaction of the monomers while dispersed throughout the inorganic fillers.
