HOW TO USE
1-  Carefully clean and dry all surfaces to be bonded.
2 - Apply AA-BOND FDA2 completely mixed adhesive to the prepared surfaces, and gently press these surfaces together.
3 - Contact pressure is adequate for strong, reliable bonds; however, maintain contact until adhesive is completely cured.
4 - 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.
5 - 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:
This epoxy can be supplied in many different packages.
