https://www.silitech.ch/web/image/product.template/3849/image_1920?unique=a6389ff

2K-Pt silicone with Shore A 45 for tool and mold making.

BLUESIL RTV 3445 is an addition-curing silicone elastomer with a 10:1 mixing ratio for model and mold making as well as the rapid production of prototypes. It combines easy processing and rapid curing with increased tear resistance and good mechanical properties at high Shore A hardness. This is the A component; curing is achieved with the corresponding B component.
