摘要： 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.

摘要： Epoxy-type impregnating compounds, which are useful for electrical potting or encapsulation, plastic tooling, and fiber-reinforced composites, comprise a resin component and a stoichiometric amount of a curative and have a curing temperature of less than about 120.degree. F. (49.degree. C.). The resin component is the diglycidyl ether of bisphenol A, either alone or as a mixture with up to about 15 wt % of at least one reactive monoepoxide diluent or up to about 50 wt % of at least one reactive diepoxide diluent, the diluent having a viscosity of less than about 200 cp. The curative is a mixture of cycloaliphatic diamines, comprising from about 20 to 80 wt % of at least one sterically-hindered cycloaliphatic diamine and the balance at least one sterically-unhindered cycloaliphatic diamine. These epoxy compounds are unique because they can be handled in relatively large bulk without concern for dangerous runaway exotherms. In addition, they result in useful products with a moderate service temperature range, without the necessity of high temperature cures. The advantages of the low temperature cure are lower residual stress in the cured product, better dimensional control in molding, and lower energy expenditure.

摘要： A superior thermal transfer film adhesive comprises the following composition: (a) at least one aliphatic epoxy resin; (b) a stoichiometric amount of at least one aliphatic polyamine curative; (c) an effective amount of a thixotropic agent, such as fumed silica; and (d) about 20 to 50 volume percent of at least one filler, such as alumina, based on the total of the epoxy resin and the curative. The aliphatic epoxy resin has aliphatic pendant chains of 6 to 20 carbon atoms in length. The curative comprises a long chain aliphatic or cycloaliphatic curing agent for the epoxy resin. Since aliphatic moieties, which are flexible, are used, the glass transition temperature of the resulting cured material is lower than epoxies and plasticizers employing rigid moieties. The adhesive of the invention is novel in attaining high volume resistivity (at least 10.sup.14 ohm-cm at 25.degree. C.), low temperature flexibility (-55.degree. C.), excellent adhesion for maximum thermal transfer, and ease of reworkability.
