SikaBiresin® CR83

(former Biresin® CR83)

Biresin® CR83 is an epoxy resin system with extremely low viscosity designed specifically for the infusion process to produce high-performance fiber reinforced composites parts and moulds. The system has thermal properties up to 80 °C. Biresin® CR83 epoxy resin has a low tendency to crystallize.

  • 3 hardeners (B) give a wide range of processing times
  • The reactivity can be adapted by mixing the hardeners
  • Fast infusion and good wet-out of fabrics and non-woven due to low viscosity and good wetting characteristics even at low temperatures
  • All systems Germanischer Lloyd approved, Certificate No. WP 1420017 HH
  • Glass transition temperatures up to 80 °C dependent on curing conditions
  • Carbon fibers are wet out well by all resin systems
  • Biresin® CR83 resin (A) has a low tendency to crystallize
