Introducing OOMOO 25, the ultimate solution for anyone looking for an easy-to-use, versatile, and high-quality silicone rubber compound. This remarkable material is specifically designed for novice mold makers, offering a convenient one-to-one by volume mix ratio, eliminating the need for a scale. The low viscosity of OOMOO 25 ensures effortless mixing and pouring, while its negligible shrinkage and 15-minute pot life make it an ideal choice for a wide range of applications. With a 75-minute cure time at room temperature, you can swiftly create precise and accurate molds without the need for vacuum degassing.

OOMOO 25 is perfect for making simple one or two-piece block molds, and it's essential to note that these silicones do not have great tear strength. If you require a high tear strength silicone, Mold Max silicones are recommended. When working with OOMOO 25, make sure to use it in a properly ventilated area, wearing safety glasses, long sleeves, and rubber gloves to minimize contamination risk.

To ensure the best results, it's crucial to follow the instructions carefully. Premix Parts A and B thoroughly, then mix for 3 minutes, scraping the sides and bottom of the mixing container several times. Pour the mixture in a single spot at the lowest point of the containment field, allowing the rubber to seek its level up and over the model. A uniform flow will help minimize entrapped air.

For optimal performance, allow the rubber to cure for 75 minutes at room temperature, followed by an additional 4 hours at 150°F (65°C) to eliminate any residual moisture and alcohol. Once cured, the mold can be demolded, and you're ready to use it. When casting, no release agent is necessary for wax or gypsum, but applying Ease Release 200 is recommended for polyurethane, polyester, and epoxy resins to prevent sticking and mold degradation.

The physical life of the mold depends on how you use it, with abrasive materials like concrete quickly eroding mold detail. Clean and dry the mold before storing, and assemble two-part molds. Store the mold on a level surface in a cool, dry environment to ensure its longevity.

As a novice mold maker, OOMOO 25 is the perfect choice for creating high-quality, precise molds with ease. With its easy-to-use formula, convenient mix ratio, and relatively fast cure time, you'll be able to create stunning molds that meet your exacting standards. Experience the convenience and versatility of OOMOO 25 and take your mold-making skills to the next level.
