Abstract

1,271,956. Foamed, hardened epoxy resins. FARBWERKE HOECHST A.G. 21 July, 1969 [20 July, 1968], No. 36653/69. Headings C3B and C3C. A foamed, hardened epoxy resin is made by mixing an epoxy resin having 2-10 epoxy groups per molecule, a liquid and/or solid expanding agent, an amine hardener which comprises one or more aromatic polyamines each containing two or more primary amino groups, and an accelerator which comprises one or more polyphenolic compounds, at a temperature within the range of from 30‹ to 80‹ C., to foam and harden the epoxy resin. A pore regulator may be mixed with the epoxy resin, and may be a polysiloxane or a block copolymer of a polysiloxane and ethylene oxide. The hardener may additionally comprise a cycloaliphatic amine and/or an aliphatic amine. The polyphenolic compound may be a novolak. The aromatic polyamine may be a condensation product of aniline and formaldehyde having a molecular weight of 200 to 600. The epoxy resin may be the reaction product of 2,2-diphenylol propane with epichlorohydrin. The expanding agent may be 1,1,2-trifluoro-1,2,2-trichloroethane.
