- Instructions for Use
Mixing
Thoroughly stir Part A prior to weighing for Part B addition as the product separates. Mix Part A with Part B in a 20: 1 ratio just prior to use.
Vacuum Deaeration
Remove air entrapped during mixing by common vacuum deaeration procedure, observing all safety precautions. Slowly apply full vacuum to a container rated for use and at least four times the volume of material being deaerated. Hold vacuum until bulk deaeration is complete
Note: Some bonding application may require the use of a primer. NuSil Technology’s CF1-135 silicone primer is recommended.
Substrate Considerations
Cures in contact with most materials, exceptions include: sulfurcured organic rubbers, latex, 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.
