Features & Benefits

Product Highlights
  • Two-part, translucent, pourable silicone system
  • Offers a high tear strength, good physical properties
  • 10:1 Mix Ratio (Part A:B)

Applications & Uses

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 a high tear strength
Instructions for Use

Mixing

Thoroughly mix Part A and Part B, in a 10:1 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.

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 applications 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 cure times and temperatures to accommodate different production needs.
