Rebound 25 Five Gallon Kit 90Lb (799305)
Rebound 25 is an easy-to-use platinum-cure silicone rubber that self-thickens for making brush-on molds of almost any model. Mixed 1A:1B by volume (no scale necessary), Rebound 25 can be applied with a brush or spatula to vertical surfaces without sagging and will cure with negligible shrinkage to a soft, flexible rubber (Shore 25A). Kit Coverage: 35 sq.ft. @ 3/8' thick.
Four thin layers is all that is necessary to make a stretchy, strong and 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, casting pewter, etc. Also available in a Shore 40A. See Rebound 40.
Note: This product will not work with modeling clays containing sulfur.
