Epoxies, Etc 20-1650 High Temperature Silicone Potting and Encapsulating Compound
Categories: Polymer; Thermoset; Silicone

Material Notes: Description: 20-1650 is a two component silicone elastomer designed for high temperature applications. Silicones offer thermal stability at high operating temperatures, but the 20-1650 is formulated with iron oxide to impart increased stability at elevated temperatures. It has a simple 1:1 mix ratio. 20-1650 can be used for potting or encapsulating electronic packages that have sensitive components. Due to its low stress during and after cure, this material will not crush or damage delicate components. 20-1650 is formulated without solvents or other toxic materials. It is therefore not regulated or considered hazardous for transportation.

Features:

  • High operating temperatures
  • Easy 1:1 mix ratio
  • Low viscosity
  • Flexible
  • Deep section curing (beyond 1-2 inches)
  • Solvent free
Benefits:
  • Good protection in extreme environmental applications
  • Simple to use
  • Dispenses and pours easily without air bubbles
  • Low stress on components and vibration resistant
  • No need for multiple pours due to low exotherm
  • No by-products released during cure and safe to handle
