The Use of 'Epoxy Fortifiers' in Adhesives Applications

Abstract

Additives for epoxy resins called epoxy fortifiers ( US Patents 4480082, 4,739,028) increase the stiffness and strength of crosslinked epoxy resins, and modify their fracture characteristics such that they fail in a ductile fashion under tensile loading. The improvements in adhesive bond performance which result from improved bulk adhesive properties are reviewed. Other benefits of fortifier addition can include acceleration of the cure, a reduction in coefficient of thermal expansion, and a reduction in the rate of water uptake. Drawbacks of fortifier addition can include a reduction in pot life, and a reduction in glass transition temperature. Adhesives, Primers, Fortifiers, Antiplasticizers, Epoxy resin.
