- Instructions for Use
Mixing
Mix in a 1:1 ratio Part A to Part B, taking care to minimize air entrapment during mixing.
Vacuum Deaeration
Removed air entrapped during mixing by common vacuum deaeration procedure, observing all applicable safety precautions. Slowly apply vacuum, up to 28 inches Hg, to a container rated for use and of volume at least four times that of material being deaerated. Hold vacuum until presence of air is no longer evident.
Substrate Considerations
Cures in contact with most materials common to electronic assemblies. Exceptions include butyl and chlorinated rubbers, some RTV silicones and unreacted residues of some curing agents. Units being encapsulated or potted should be clean and free of surface contaminants. Containers and dispensers being used should also be clean and dry. Cure inhibition can usually be prevented by washing all containers with cleaning solvent or volatilizing the contaminants by heating. Note: Some bonding applications may require the use of a primer. NuSil Technology LS1-3200 silicone primer is recommended.
Adjustable Cure
Schedule Product cures at a wide range of cure times and temperatures to accommodate different production needs.
