IRS 2013 is a black, flexible epoxy encapsulant resin system. Its low viscosity and fast room temperature cure make it an ideal potting compound when low stress or adhesion to flexible substrates is required.

Features & Benefits

  • Low viscosity, unfilled system
  • Excellent potting and encapsulation system with good flow properties
  • Cures quickly at room temperature, but with relatively low exotherm
  • High flexibility and low exotherm results in a low stress system
  • Good adhesion to a wide range of substrates, but very high peel strengths on flexible substrates
  • Good shock resistance due to flexibility
  • Excellent electrical properties
  • Good chemical resistance to solvents, oils, fuels, acids and bases
  • Black, high gloss finish
  • Available in easy-to-use twinpacks
