  • Aqueous based epoxy resin curing agents
    Patent number: 4608405
    Abstract: The instant invention is an epoxy resin curing agent based upon an epoxidized polyol containing aromatic and polyalkylene ether moities in which substantially all of the epoxide groups are reacted with a polyamine wherein each primary amine in the resulting reaction product is further reacted with a monoepoxide or a monocarboxylic acid. The resulting epoxy resin curing agent may be used in a water based system for curing epoxide resins. The curing agent is rendered water soluble or water dispersible by salting with a conventional volatile monocarboxylic acid such as acetic, formic or propionic acid.

    Date of Patent: August 26, 1986
    Assignee: Celanese Corporation
    Inventor: William J. DeGooyer
  • Novolac based epoxy resin curing agents for use in aqueous systems
    Patent number: 4539347
    Abstract: The instant invention is an epoxy resin curing agent based upon an epoxy novolac containing, on the average, between about 3 and about 7.5 epoxy groups per molecule, in which substantially all of the epoxide groups are reacted with a polyamine wherein each primary amine hydrogen in the resulting reaction product is further reacted with a monoepoxide or a monocarboxylic acid. The resulting epoxy resin curing agent may be used in a water based system for curing epoxide resins. The curing agent is rendered water soluble or water dispersible by salting with a conventional volatile monocarboxylic acid such as acetic, formic or propionic acid.

  • Novolac based epoxy resin curing agents for use in solvent
    Patent number: 4525542
    Abstract: The instant invention is an epoxy resin curing agent based upon an epoxy novolac containing, on the average, between about 3 and about 7.5 epoxy groups per molecule, in which substantially all of the epoxide groups are reacted with a polyamine wherein each primary amine hydrogen in the resulting reaction product is further reacted with a monoepoxide. The resulting epoxy resin curing agent may be used in a solvent based system to cure epoxy resins under low temperature curing conditions.
