Abstract
A flexible epoxy adhesive composition comprising a mixture of a fatty acid modified epoxy resin and an oxypropylene epoxy resin in the ratio of about 1:3 to 1:1. The adhesive paste also includes a stoichiometric amount of a polyamine curing agent, 1 to 20 total liquid weight percent of a plasticizer and 1 to 5 weight percent of microfine silicon dioxide particles. Fillers, such as aluminum oxide and glass beads, are optionally added. This adhesive paste is particularly well suited for use as a flat pack adhesive to provide a releasable bond and is also well suited for use in space applications.
