Our Gesswein Resin Release spray is a non-silicone formula designed to protect rapid prototype models as well as most silicone mold rubber out in the market. Using Resin Release Spray before vulcanizing allows you to make production-quality molds directly from CAD/CAM resin and wax models. These 11.5 oz. aerosol cans are sold individually or in a case of 12 cans.   Can should be held 8-12 inches from the pattern while applying a light even spray covering for optimal results and improved finish.
