Rebound 40
Product Code:SOSRB405G
An easy-to-use platinum-cure silicone rubber that self-thickens for making brush-on molds of almost any model. Can be applied with a brush or spatula to vertical surfaces without sagging and will cure with negligible shrinkage. Rebound 40 is hard and not very flexible. Stands up well to production casting of resins and low temperature metal melt alloys. Cured molds have a long library life. Although not necessary, adding a small amount of Silc Pig color pigment to every other mix of rubber will help you distinguish one layer from the next. Add Thi-Vex thickener for greater thixotropy. Once the mold is fully cured, a rigid support shell (mother mold) is needed to support the rubber mold during casting. Plasti-Paste II is ideal as a mother mold material.
