HOW TO USE:
1) Carefully clean and dry all surfaces to be bonded.
2) Apply Silver-Bond 79 Silver Epoxy Adhesive, One Part, Electrically Conductive, Bonding 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 52C 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 various different packages.
