THERMOSETTING RESIN CASTING PROCESS, PRODUCT AND DEVICE

摘要

A process for producing cast unsaturated thermosetting resins which are highly stain resistant is disclosed. A pressurization step is applied to the thermosetting resin prior to casting to reincorporate any volatilized monomer which has volatilized during a previous deaeration step. The resultant casting is nonporous in cross-section which produces a product which is both stain resistant and machinable in the field without exposing voids.
