Smooth-On - Rebound 40 Silicone Tin-Cure Rubber Trial Unit

Rebound™ 40 is an easy-to-use platinum-cure silicone rubber which self-thickens for making brush-on molds of almost any model. Mixed 1A:1B by volume (no scale necessary), Rebound™rubber can be applied with a brush or spatula to vertical surfaces without sagging and will cure with negligible shrinkage to a flexible rubber.

Features

Rebound™ 40 is hard and not very flexible. It is compatible with Rebound™ 25. 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.
