Abstract: A curable adhesive composition includes a curable epoxy resin, an amine curing agent, a toughening agent, and aluminum flakes. The aluminum flakes include a fatty acid milling aid on at least a portion of their surfaces. The aluminum flakes were heated after milling. An article includes an adhesive composition cured between at least two members. The cured adhesive composition includes the heat-treated aluminum flakes within a toughened epoxy resin cured with an amine curing agent. The method includes applying the curable adhesive composition of described above to a surface of at least one of two or more members, joining the members so that the curable adhesive composition is sandwiched between the two or more members, and curing the curable adhesive composition to form an adhesive bond between the two or more members.

Abstract: A curable composition and a method of making a cured composition are provided. The curable composition contains at least two parts with the first part containing three different types of curing agents that contain multiple —NHR1 groups (R1 is hydrogen, alkyl, aryl, aralkyl, or alkaryl) and with the second part containing an epoxy resin. The first part composition and the second part compositions are selected to control the rheology of the curable composition both before and after combination of the first part with the second part.
