Room Temperature Curing Epoxy Resin Compositions High Temperature Service Capability for Fiber Reinforced Structures, Adhesives and Sealants

摘要

Room temperature curing epoxy resin compositions with high temperature service capability based on selected high functionality epoxy polymers and multicomponent curing agent systems were formulated and evaluated as binders for glass fiber reinforced laminates, adhesives and sealants. Experimental data have been developed which show that certain suitably formulated two-component epoxy resin compositions can be employed to prepare glass fiber reinforced composites for service up to 200 C. Their high temperature performance capability significantly exceeds that of other commercially available room temperature curing systems such as polyesters and acrylics. Data are also presented on similarly formulated adhesive compositions which show promise for usage over an exceptionally wide temperature range. (Author)
