GENERAL INFORMATION:
For safe handling information on this product, consult the
Material Safety Data Sheet, (MSDS).
HOW TO USE:
1.
1-
Carefully clean and dry all surfaces to be bonded.
2 -
Apply
AA-BOND FDA22
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.
AVAILABILITY:
This epoxy can be supplied in many different packages.
