Use these silicone mold making rubbers for making perfect reproductions of original models. They capture intricate detail and are easy to use. OOMOO 30 and OOMOO 25 are easy to use silicone rubber compounds that feature convenient one-to-one by volume mix ratios (no scale necessary). Very low viscosity for easy mixing and pouring, and vacuum degassing is not necessary. Cures at room temperature with negligible shrinkage. OOMOO 30 has a 30-minute pot life, with a six-hour cure time. OOMOO 25 has a 15-minute pot life with a 75 minute cure time. For The Novice Mold Maker - OOMOO 30 and OOMOO 25 do not have great tear strength. They are good for making simple one- or two-piece block molds. OOMOO 30 and OOMOO 25 are suitable for a variety of art-related and industrial applications including making molds for sculpture and prototype reproduction, casting plaster, resins, and wax. Net weight 2.9 lbs.
