No Vacuuming – No Scale – Easy To Use . . . OOMOO™ 25 is an easy to use tin cure silicone rubber compound that features a convenient one-to-one by volume mix ratio (no scale necessary). It has a low viscosity for easy mixing and pouring . . . vacuum degassing is not necessary. This product cures at room temperature with negligible shrinkage. OOMOO™ 25 has a 15-minute pot life and 75-minute cure time.
For The Novice Mold Maker - OOMOO™ silicones do not have great tear strength. They are good for making simple one or two-piece block molds. If you require a high tear strength silicone, Mold Max™ silicones are recommended.
OOMOO™ 25 is suitable for a variety of art-related and industrial applications including making one and two-piece block molds for sculpture and prototype reproduction, casting plaster, resins and wax. OOMOO™ silicones are also suitable for electrical potting and encapsulation applications.
