SikaBiresin® CR132

Composite resin system for hand lay-up process with Tg up to 135 °C

SikaBiresin® CR132 is an epoxy resin system suitable for the production of high performance fiber reinforced composite components and molds in hand lay-up where a high termal resistance of up to 135 °C is required.  

  • Good impregnation of dry fabrics and non-draining properties
  • Tg up to 135 °C
  • Three hardeners (B) give a wide range of processing times
  • Hardeners (B) are pigmented blue to assist in mixing and process control

Application

Application Information

Application

The resin system is optimized for processing temperatures between 18 °C – 25 °C. Consider the change in processing parameters if the resin system is processed at different temperatures. The curing must be performed at temperature ≥ 18 °C.
Prior to application, check both components for crystallization. The crystallization process can be reversed by heating the product to 60 °C – 70 °C until the crystals are no longer visible.
Containers must be closed tightly immediately after each use to prevent moisture ingress.

Removal

Uncured SikaBiresin® CR132 can be removed from tools and equipment with Sika® Reinigungsmittel 5 or another suitable solvent. Once cured, the material can only be removed mechanically. Hands and exposed skin shall be washed immediately using industrial hand cleaner and water.
Do not use solvents on skin.

STORAGE CONDITIONS

All components must be stored between 15 °C – 30 °C.

Prior to use check the material for homogeneity and crystallization and make sure to temper it to processing temperature.
