Overview
PRODUCT BENEFITS
- Low viscosity and good wetting characteristics in heated injection process
- Suited for fast cycle times
- High temperature resistance
Areas of Application
SikaBiresin® CR144 CH100-1 is suited for injections processes due to its viscosity and reactivity. It can be used in areas where higher temperature resistance and short cycle times are required.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 injection temperatures between 45 °C – 80 °C. Consider the change in processing parameters if the resin system is processed at different temperatures. The mould temperature can vary depending on the process. For isothermal processes the mould temperature can be between 60 °C – 140 °C, for variothermal processes between 60 °C – 180 °C.
Information regarding viscosity development at different temperatures are shown in the diagram below.

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® CR144 CH100-1 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.
