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

Usage

Biresin® CR83 is especially suited to the infusion and injection processes due to its low viscosity range. It can be used in the marine and general industrial composite areas. Due to its good wetting properties it is particularly suited for its with carbon fiber reinforcement.
