There has never been an easier to use brush-on silicone rubber than Rebound® 25. Mixed 1A:1B by volume (no scale necessary), Rebound 25 self thickens and will hold a vertical or inverted surface and will cure to a soft, flexible rubber (Shore 25A) that is incredibly strong. Addition cured silicone rubber may be inhibited by certain contaminants in or on the pattern to be molded resulting in tackiness at the pattern interface or a total lack of cure throughout the mold. Sulfur clays, certain wood surfaces, newly cast polyester, epoxy or urethane rubber may cause inhibition. If compatibility between the rubber and the surface is a concern, a small-scale test is recommended. See further details on the Rebound 25 technical bulletin.

Advantages Over Urethane Brush-On Rubber:

  1. Rebound 25 will not stick to most surfaces, so surface preparation is minimal.
  2. Two liquids that mix easily together.
  3. Rebound 25 sticks to itself readily, even when cured, meaning material can be added any time.
3 to 4 layers is all that is necessary to make a strong, durable production mold for casting wax, gypsum, concrete or resins (urethane, polyester, etc.) and because Rebound 25 is a platinum silicone, it will last for many years in your mold library.

Applications include reproducing sculpture, architectural restoration, making candle molds, and more.
