Unit Size Net Weight Pint Kit 2 lb Gallon Kit 18 lb Five Gallon Kit 90 lb Rebound¨ 25 and Rebound¨ 40 are easy-to-use platinum-cure silicone rubbers which self-thicken 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. 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. Note: This product will not work with modeling clays containing sulfur.
