PRODUCT BENEFITS

  • Flame retardant according to UL94 V-0 with SikaBiresin® CH132-5
  • Wide range of processing times
  • Very good wetting properties and high transparency compared to other filled flame retardant systems
 

Areas of Application

SikaBiresin® CR134 FR is especially suited for the hand lay-up process and can be used for general industrial composite parts which require fire retardance properties and a high thermal resistance. This product is suitable for experienced professional users only. Tests under actual processing conditions and with additional materials such as fibers and release agents must be performed to proof material compatibility.

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® CR134 FR 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.
