Rio Cold Mold RTV Silicone Compound Kit

Two-part Rio Cold-Mold™ silicone compound delivers 0% shrinkage without heat. No release agents needed—excellent for molding originals or master models. Ideal for metal clay users! You can use this mold-making system with natural rubber compounds, too. Natural rubber compounds must be heat-cured in a vulcanizer or an oven at the appropriate temperature for the material being used.
