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.

Automobile panel repair laminates include a pressure sensitive adhesive bonded to a support backing. The support backing may be constructed of various materials such as plastically deformable polymeric materials including thermoplastic or thermoset materials and may have various thicknesses depending upon the desired conformability and rigidity necessary for the repair. The support backing may be bonded to the pressure sensitive adhesive by applying adhesion promoters such as solvents. The repair laminate is applied to a back or non-aesthetic side of the automobile panel, and the front side is repaired using standard techniques for filling and finishing.

The present invention provides a backing for a coated abrasive article, wherein the backing includes a tough, heat resistant, thermoplastic binder material, and an effective amount of a fibrous reinforcing material distributed throughout the thermoplastic binder material. The tough, heat resistant, thermoplastic binder material and the fibrous reinforcing material together form a hardened composition that will not substantially deform or disintegrate during use.
