Introduction

Abstract

Epoxy adhesives are composed of epoxy resin, curing agents, and catalysts with modifiers and additives. Bisphenol A-based epoxy resin, bisphenol F-based epoxy resin, novolac type epoxy resin, aliphatic glycidyl ether epoxy resin, glycidyl amine epoxy resin, glycidyl ester epoxy resin, and cycloaliphatic epoxy resin are typical epoxy resins. Polyamine, modified polyamine, mercaptan, phenol, anhydride, tertiary amine and imidazole compounds, and cationic initiators are typical curing agents and catalysts. Epoxy adhesives are supplied in both one-component and two-component packages depending on the curing agent used and the curing method applied. Typical room temperature cure epoxy adhesives, thermal cure epoxy adhesives, UV cure epoxy adhesives, and new trends in epoxy adhesive technology developments are described.

Keywords: Curing agent, Epoxy resin, Epoxy adhesive, One-component, Room temperature cure, Two-component, Thermal cure, UV cure.
