ABSTRACT:
Epoxy resins are cured with salicyloyl hydrocarbyl amines such as N,N'-disalicyloyl-1,2-propylenediamine. The cured resins have an improvement in one or more properties such as color, tensile strength and flexural strength or improved pot life when compared to amine curing agents such as methylene dianiline.
