OOMOO® 25 is an easy to use silicone rubber compound that features a convenient one-to-one by volume mix ratio (no scale necessary). It has 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, with a 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.
