Description of casting mould 2 parts liquid addition silicone
RTV2 Silicone Mold Making Rubber , Addition Silicone Rubber, is general called two-component room temperature vulcanization silicone rubber with excellent fluidity and good operational performance. Add curing agent of 2% at the room temperature, the silicone rubber is still operational within 30 minutes, and in 4-6 hours, an elastic silicon mold will be obtained with resistance to deformation, high-temperature, acid and alkali and expansion. The silicone rubber is mainly applicable to mold duplication of poly crafts, resin craftworks, lightings, candles, etc. And fabrication of precision molds.
