Rebound™ 25 is soft, flexible and is good for making molds of models with deep undercuts. Depending on model configuration, Rebound™ 25 can be inverted as a glove molds. Rebound™ 40 is harder and less flexible. These products are compatible. For example, you can apply two coats of Rebound™ 25 and back it up with two coats of Rebound™ 40.
Advantages Over Urethane Brush-On® Rubber:
- Rebound™ will not stick to most surfaces, so surface preparation is minimal
- Two liquids that mix easily together
- stands up better to production casting of resins and low temperature melt metal alloys
- has a long library life
4 thin layers are all that is necessary to make a flexible, strong and durable production mold for casting wax, gypsum, concrete or resins (urethane, polyester, etc.). And because Rebound™ is a platinum silicone, it will last for many years in your mold library. Applications include reproducing sculpture, architectural restoration, making candle molds, casting pewter, etc.
Note: These products will not work with modeling clays containing sulfur under any circumstances.
