- 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.
Note: Some bonding applications may require the use of a primer. NuSil Technology’s LS1-3200 and LS4-3200 are recommended.
Substrate Considerations
Cures in contact with most materials common to biomedical assemblies. Exceptions include: sulfur-cured 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.
