Overview

PRODUCT BENEFITS

  • Flame retardant: UL94 V-0 classification
  • Very good wetting and non-draining properties
  • High temperature resistance
 

Areas of Application

SikaBiresin® CR132 FR CH132-5 is especially suited for the hand lay-up process and can be used in general industrial composite applications which demand higher thermal resistance and flame retardance.
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

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 FR CH132-5 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.
