- Instructions for Use
Mixing
Thoroughly mix in a convenient 1:1 mix ratio by weight prior to use.
Vacuum Deaeration
Remove air entrapped during mixing by common vacuum deaeration procedure, observing all applicable safety precautions. Slowly apply full vacuum to a container rated for use and at least four times the volume of the material being deaerated. Hold vacuum until bulk deaeration is complete.
Substrate Consideration
Cures in contact with most materials. Exceptions include butyl and chlorinated rubbers, some RTV silicones and unreacted residues of some curing agents.
Adjustable Cure
Schedule Product cures at a wide range of cure times and temperatures to accommodate different production needs.
