Brush silicone rubber(RTV-2) :
production mold casting wax, gypsum, concrete or resins (urethane, polyester, etc.). Applications include reproducing sculpture, architectural restoration, making candle molds, casting pewter, place couldn't pour rubber over the above etc. For make a mold by brushing (or spraying) rubber onto the model. Rubber will hold a vertical surface and will reproduce the finest detail brushed onto the model in layers until a suitable thickness is "built up." The rubber is allowed to cure and a support shell is applied prior to demold. The advantage of making a mold by brushing rubber onto the model is that it minimizes the amount of rubber used, saving material costs
Spray silicone rubber(RTV-2)
For making fast sprayed rubber molds that have the best release properties for production casting of resins, plaster, etc. it is a tin silicone rubber that self-thickens for making concrete Spray able -on molds . Properly applied, Mixed 100A:10B by weight, rubber quickly develops thixotropy when mixed in air. Cured with negligible shrinkage to a durable mold rubber good for production casting resins, foams,concrete, plaster and other materials. Application of a support shell is achieved by spraying over the rubber mold after it has fully cured
