Polytek Molding & Casting Editorial Review
This liquid rubber is a great product that is easy to mix and has excellent hardness and tear strength for small and complex plastic parts. It can be used with silicone molds to cast silicone parts, and the light green color is a nice touch. The cure time needs to be at room temperature, and the cure needs at least double the amount of time to attain full strength. Mixing it well is crucial, but it copies even small details without the need to use a release agent.
