  • Thermosetting resin casting process, product and device
    Patent number: 4652596
    Abstract: 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 non-porous in cross-section which produces a product which is both stain resistant and machinable in the field without exposing voids.

  • Cast polyester resin process and product
    Patent number: 4473673
    Abstract: A pretreatment process to remove entrapped air from liquid polyester blends intended as the matrix of cast marble is disclosed. The formulated blend is subjected to a simultaneous evacuating, vibrating and shearing step which is critical within broad parameters. The thus treated blend, after casting, will be non-porous in cross section, thereby making it suitable for countertops and other parts which must be field cut to specifications.
