Case 4840 - 10/02/1985 Abstract of the Disclosure Novel phenolic molding compositions comprise (1) a resole phenolic resin, (2) an alkaline earth metal hydroxide or oxide, and/or a silane compound, and (3) a mixture of clay and talc fillers and/or microballoons. The composition also generally contains a mold release agent, and a silane coupling agent. The alkaline earth metal hydroxide or oxide is preferably calcium and/or magnesium hydroxide or oxide. A mixture of the calcium and magnesium compounds is most preferred. The foregoing molding compositions are applied to glass fibers or filaments to provide compositions useful in sheet molding compound processes, pultrusion processes, filament winding, and continuous laminating processes, as well as in ram injection molding and transfer molding.
