GENERAL INFORMATION
For safe handling information on this product, consult the Material Safety Data Sheet, (MSDS).
HOW TO USE
- Carefully clean and dry all surfaces to be bonded.
- Apply AA-BOND FDA2T 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.
- 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.
- 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.
AVAILABILITY
