Product Details

This silicone rubber is self-thickening and can be applied with a brush or spatula to vertical surfaces without sagging. It cures with insignificant shrinkage to a soft, flexible rubber. It does not stick to most surfaces, minimizing surface prep time, and features an easy part 1A:1B by weight or volume mix ratio. Four thin layers are all that is required to make a stretchy, strong and durable production mold for casting wax, gypsum, concrete or resins like urethane or polyester.
