Silicone rubber KDSV-25 525g

Silicone rubber KDSV-25 (set of two components). KDSV-25 is a pourable, condensation curing 2-component silicone rubber for replicas using cast ceramic, plaster, polyester and polyurethane resins (please use priming wax as protective film on epoxy). As both component batches are matches to each other, we only supply complete batches. It is not possible to obtain individual deliveries of silicone and hardener. Good flowability Fast vulcanisation at room temperature Good tear strength and tear propagation strength.
