Abstract

Epoxide resins, i.e. glycidyl ethers obtained by the reaction of a polyhydric aromatic compound, formed by the condensation of a phenol with a ketone or an aldehyde, with a compound having a glycidyl radical or a compound capable of yielding a glycidyl radical under the condensation reaction conditions are hardened by an alkyl substituted mono-nuclear aromatic diamine containing two primary amine groups attached directly to the aromatic nuclus. The alkyl substituents contain 1-5 C. atoms and more than one alkyl group may be substituted in the nucleous; m-toluylene diamine is specified. An epoxide resin was prepared by heating a solution consisting of 11.7 parts water, 1.22 parts NaOH and 13.38 parts diphenylol propane to 70 DEG C. and then cooling to 45 DEG C. and adding 14.06 parts epichlorhydrin. The product was washed and dried in vacuo to give a viscous liquid resin; 10 gs. of mixed isomers of m-toluylene diamine were added to 100 gs. of the resin and a product having a pot life of 8 hours at room temperature was obtained which was suitable as a bonding medium for glass cloth laminates or for potting electrical components. A second resin was obtained by reacting phenol and paraformaldehyde in presence of boron trifluoride-ethyl etherate to give a phenol-formaldehyde condensate which was reacted with epichlorhydrin in presence of alkali.
