RTV-2 Silicone Rubbers for Shoe Sole Mold Production
NEVOSIL® SK 323
RTV-2 Silicone Rubber, Condensation Curing
NEVOSIL® SK 323 is a condensation-curing, two-component silicone rubber which vul-canizes at room temperature.
NEVOSIL® SK 323 is particularly suitable for the production of shoe sole molds. NEVOSIL® SK 323 should be used for the reproduction of models with pronounced undercuts (exp; plaster, gypsum, candle or wax models).
