Applications & Uses

Application Method
Compatible Substrates & Surfaces
Applications
  • For coating, sealing and bonding applications requiring solvent and/or fuel resistance
  • Designed for spraying, dip casting, and RTV curing of thin, elastomeric films
  • For use as a coating to minimize ice adhesion
  • Bonds aggressively to most surfaces
  • Slight addition of heat will accelerate cure
Instructions for Use

Mixing

Thoroughly mix prior to use and/or further solvent addition. Exercise care to prevent solvent loss during deairing. Accomplish additional dilution for thin film applications by adding appropriate solvent, followed by mixing and deairing.

Warning: Consult the MSDS for R-3930 prior to use as the solvent carrier is hazardous.

Surface Preparation

Clean the surface with an organic solvent (e.g. tert butyl acetate). Follow solvent cleaning with an IPA wipe. Wait 15 minutes until all the solvent has evaporated before the application of any materials. If applicable, apply adhesion promoter (primer) such as NuSil Techology SP-120 or SP-121 and allow 30 minutes for the adhesion promoter to cure. Keep the surface clean and free of dust and particulates until the dispersion is applied.
