  • Patent number: 5082878
    Abstract: New shrinkage control agents, for unsaturated polyester resin systems, which are copolymers of vinyl versatate and vinyl acetate, i.e., poly(vinyl versatate-co-vinyl acetate). The shrink control agents are useful both with neat and filled unsaturated polyester resin systems. The shrink control agents are especially useful under conditions where the unsaturated polyester resin system is cured at or below ambient temperatures.

  • Patent number: 5077326
    Abstract: A quickly curable unsaturated polyester composition with high surface quality contains an unsaturated polyester, a vinyl monomer, either an alkane polyol polyacrylate or an alkane polyol polymethylacrylate, a thermoplastic resin, and one or more curing catalysts selected from t-butylperoxy benzoate, t-butylperoxy octoate and 2,5-dimethyl-2,5-di(benzoilperoxy) hexane. Molding compounds are obtained by impregnating glass fibers with such composition and molded products obtained by curing such molding material have improved surface smoothness.

  • Patent number: 4992490
    Abstract: A coating composition is described that is comprised of (1) polyacrylate fibers, (2) at least one monomer which forms an acrylic polymer, (3) styrene monomer, (4) unsaturated polyester resin, (5) a polymerization inhibitor (to prevent premature polymerization prior to application), and (6) an inert carrier in which each acrylic polymer-forming monomer and the styrene monomer are soluble. The inert carrier described and the miscible/soluble components form a medium wherein polyacrylate fiber suspension is easily achieved and maintained. The coating composition can be used as a base coat or primer without need for finishing prior to application of an overcoat of paint.
