  • Polyurea thickened molding compositions
    Patent number: 4296020
    Abstract: Ethylenically unsaturated monomer solutions of ethylenically unsaturated polyester, polyester urethane and polyisocyanurate resins are quickly converted to moldable gels by the homogeneous formation therein of polyurea resins by the interaction of polyamines and polyisocyanates. Tack-free handleable moldable gels are formed within minutes which can be stored under normal conditions for long periods of time until molded. Fully cured intractable articles are formed by the polymerization of the ethylenically unsaturated ingredients.
