Product Description
Here you will find a self-adhesive liquid silicone rubber designed for making industrial rubber parts. It is two-component liquid silicone rubber suitable for injection molding. Hardness is up to 50 Shore A. Mixing ratio is 1:1. At 20℃, as two components have been mixed, the industrial silicone can be safely used for 5 days under the condition of sealing. The time will be shortened as the temperature rises.

Features
1. Self adhesion
2. Excellent adhesive property
3. Excellent mechanical strength
4. Superior thermal stability
5. Remarkable aging resistance

Applications
The liquid silicone rubber is suitable for injection over molding of parts without primer.

Packaging
20kg/pail or 200kg/pail
