    摘要: The subject invention relates to a foundry binder system that cures in the presence of a volatile amine curing catalyst. The binder system comprises (a) a compound containing at least two active methylene hydrogen atoms, (b) an organic polyisocyanate (c) a reactive unsaturated acrylic monomer and/or polymer, (d) an oxidizing agent, and preferably (e) an epoxy component. The foundry binders are used for making foundry mixes. The foundry mixes are used to make foundry shapes that are used to make metal castings.

    摘要: A method of producing a flexible laminate and a flexible laminate produced by the method are provided. The method involves laminating flexible substrates with a urethane adhesive and allowing the urethane adhesive to cure. The urethane adhesive comprises at least one polyisocyanate, at least one polyfunctional curative, at least one metal based catalyst and a catalyst blocking agent. The catalyst blocking agent allows for improved control of the curing rate of the urethane adhesive in the flexible laminate. The curing rate of the urethane adhesive can be controlled with heat or actinic radiation or both. The method allows for faster and more economical production of flexible laminates.

    摘要: The liquid oligomeric compositions of this invention are made by the Michael addition reaction of acetoacetate functional donor compounds with multifunctional acrylate receptor compounds where the equivalent ratios of multifunctional acrylate to acetoacetate vary from .gtoreq.1:1 to .gtoreq.13.2:1 depending on the functionality of both multifunctional acrylate and acetoacetate. Unuseable gelled or solid oligomer products occur below the claimed ranges. The liquid oligomers of this invention are further crosslinked to make coatings, laminates and adhesives.
