Abstract
Epoxy adhesive compositions contain an epoxy resin, rubber modification, a toughener and a curing agent. The tougher has capped epoxide-reactive groups, and at least one polytetrahydrofuran block having a mass of 2200-4500 daltons. The selection of toughener in a rubber-modified epoxy-based structural adhesive provides for very good low temperature performance.
