Applications & Uses
- Applications
- Application Area
- Applications
- For applications requiring low outgassing and minimal volatile condensables under extreme operating conditions
- To provide protection of electric components and assemblies against shock, vibration, moisture, dust, chemicals and other environmental hazards
- Ideal for use in potting connectors, cable harness breakouts, molded high-voltage terminals, seals and gaskets due to its high tear strength
- For use as an adhesive
- For applications requiring a broader operating temperature range
- Instructions for Use
Mixing
Mix Part A and B in a 1:1 mix ratio by weight. CV-2289-1 is ideal for static mix and dispense application.
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.
Inhibition Concerns
Cures in contact with most materials common to electronic assembles. 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 contaminates. Containers and dispensers being used should also be clean and dry. Cure inhibition can usually be prevented by washing all containers with solvent or volatizing the contaminant by heating.
Note: Some bonding application may require the use of a primer. NuSil Technology CF1-135 silicone primer is recommended.
Adjustable Cure
Schedule Product cures at a wide range of temperatures and cure times to accommodate different production needs.
