  • Epoxy resin composition and process for preparing laminates therefrom
    Patent number: 4661568
    Abstract: The epoxy resin composition is comprised of an epoxy resin, a solvent and a hardener which is the reaction product of a hexa-alkyl ether of a methylol melamine having the general formula (I), wherein each R, independently, is an alkyl radical having from 1 to 4 carbon atoms with a polyhydric phenol and, optionally, a monohydric phenol, with the phenol compound(s) having been employed in an amount to provide a ratio of at least one reactive phenolic hydroxy group for each alkoxy group.
