Epoxies, Etc 20-2121 Elastomeric Potting & Encapsulating Compound
Categories: Polymer; Thermoset; Silicone

Material Notes: Description: 20-2121 is formulated for electronic potting, encapsulating and casting applications. The 20-2121 is a two-component, low viscosity, room temperature curing system. This is an easy to use product that does not contain TDI, MbOCA or Mercury. 20-2121 will cushion and protect sensitive electronic components. It will impart very little stress on components during cure or thermal cycling. The base Natural Oil Polyol (NOP) used in 20-2121 is obtained directly from a plant source without chemical modifications. Due to the raw materials selected, this product is low in toxicity and considered a GREEN potting compound. Using renewable resources such as NOPs will reduce the demand on non-renewable fossil fuels and reduce the overall production of carbon dioxide.

Features:

  • Low Toxicity
  • Green
  • Low Viscosity
  • Low Durometer
  • Moisture Resistant
  • Convenient Mix Ratios
  • Low Shrinkage & Exotherm
Benefits:
  • Reduce employee exposure to dangerous chemicals
  • Reduce demand on non-renewable fossil fuels
  • Quick self leveling around components
  • Low stress on components & vibration resistant
  • Can be used in wet environments
  • Will not damage components during cure
