Abstract
The present invention relates to a non-thermosetting composition made by reacting epichlorohydrin and a primary amine, to the use of that composition for making thermosetting (curable) adhesives suitable for bonding composites, to a method of preparing composites using the thermosetting (curable) adhesives, and to the related composites bonded with the thermosetting (curable) adhesives.
Claims1
A non-thermosetting, reaction product of (a) epichlorohydrin and (b) an amine selected from the group consisting of ammonia, a primary amine and mixtures thereof, wherein the reaction product is produced by reacting the epichlorohydrin and the amine in a ratio of 0.40 to 0.92 moles of epichlorohydrin per atom equivalent of amine hydrogen and wherein the epi-amine reaction product is produced by reacting in a serial fashion separate portions of the epichlorohydrin and separate portions of the amine at a temperature of not greater than 60° C.
