In chemistry, a fatty amine is any amine attached to a hydrocarbon chain of eight or more carbon atoms in length. These compounds are classified as oleochemicals. More commonly fatty amines are derived from C12-C18 hydrocarbons, which in turn are derived from the more abundant fatty acids. They are often mixtures. Commercially important members include coco amine, oleylamine, tallow amine, and soya amine. Some applications of these compounds are in fabric softeners, froth flotation agents (purification of ores), and corrosion inhibitors. They are the basis for a variety of cosmetic formulations.

The present invention is directed to an adhesive composition, which comprises an epoxy resin, a coupling agent, filler, and an effective amount of an amine-curing agent or curative for said epoxy resin. Advantageously, tri-functional and / or tetrafunctional epoxy resins and / or acrylate monomers will be incorporated into the adhesive composition in order to reduce open time and enhance substrate adhesion. Advantageously, a mixture of amines will be used in the curative including aliphatic amines, which have low viscosities and efficiently wet the substrate for enhancing adhesion; polyamines, which can be used to manipulate open time and allow for improved ratio tolerance of the adhesive system; and amine-terminated rubbers (ATBN), which can improve impact resistance and the toughness of the cured adhesive. Preferred coupling agents are silanes.
