Users Instructions
RTV—2 molding silicone rubber (silicon) and silicon are generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability．When mixed with 4％一5％ curing agent, they can still be operable within 35 minutes, but it will be formed after 3-5 hours．With a favorable resistance to deformation, high temperature, acid & alkali, and expansion, silicon flexible molds are used for mold duplication and delicate mold making for poly crafts, resin crafts, lighting and candle crafts, etc.
