  • Epoxy resins containing as a latent catalyst/accelerator halogenobisphenates of tertiary amines
    Patent number: 4499246
    Abstract: A catalyst and accelerator for an epoxy system which consists of a halogeisphenate of a catalytically active tertiary amine and which is obtained in a solid form practically water insoluble and odor free but which nevertheless possess the catalytic activity of the tertiary amine. The application describes the proportion of the catalyst by reacting an aqueous suspension of the halogenobisphenol with the tertiary amine, the proportion of epoxy resin systems containing the catalyst and the epoxy resin systems thus formed.
