AA-BOND 2212-1

Technical Product Bulletin

High Temperature Epoxy Adhesive


AA-BOND 2212 was developed for high temperature bonding, laminating, filament winding and potting applications where the combination of good physical and mechanical properties plus superior wetting and handling characteristics is required. This dark amber, all liquid formulation contains no solvents, and is easily mixed, handled and applied at room temperature, however a final elevated-temperature cure step is required for complete cure. AA-BOND 2212 develops strong, tough bonds to metals, glass and glass fabrics, ceramics and many other electronic an aerospace materials. The fully cured adhesive exhibits low weight loss and an improved retention of mechanical properties at elevated service temperatures. It also displays excellent chemical resistance and low permeability to gases and vapors coupled with superior electrical insulation properties. In addition, AA-BOND 2212 provides very good resistance to water, weather, jet fuels, most petroleum products, salt solutions, mild acids and alkalis, and many other organic and inorganic compounds. For masses over 1/4 gram, step cure the material for 2 hours @ 75°C, followed by 1 hour @ 150°C. This step cure schedule can also be used for low stress applications.

For safe handling information on this product, consult the Material Safety Data Sheet, (MSDS).


1) Carefully clean and dry all surfaces to be bonded.

2) Apply AA-BOND 2212 completely mixed adhesive to the prepared surfaces, and gently press these surfaces together. Contact pressure is adequate for strong, reliable bonds; however, maintain contact until adhesive is completely cured.

3) Some separation of components is common during shipping and storage. For this reason, it is recommended that the contents of the shipping container be thoroughly mixed prior to use.

4) Some ingredients in this formulation provided may crystallize when subjected to low temperature storage. A gentle warming cycle of 52°C for 30 minutes prior to mixing components may be necessary. Crystallized epoxy components do not react as well as liquid components and should be re-dissolved prior to use for best results.


This epoxy can be supplied in various different packages.
