Description
Product Details

A special, two-component, red silicone rubber. The mass has very low shrinkage during curing (addition system) and excellent mechanical properties. To adjust the hardness of the pad, it is mixed in the appropriate proportion with AK35 silicone oil. Typically, the mass has poor adhesion to other materials. To increase adhesion, use the G790 primer.

Other products from this group are also available. Please ask the salesperson for details.
