ELASTOSIL RT 620 A/B 33kg Wacker Chemie
A two-component (RTV-2), transparent silicone material with excellent tear strength. Used for printing pad molding. Neutral, addition-curing system. Excellent mechanical properties. For use with AK 35 and G 790. Manufacturer's part number: 000009556.
A special, two-component, transparent 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.
