RTV-2 molding silicon rubber

RTV-2 molding silicon rubber and silicon are generally named as two part room temperature sulfurated silicon rubber, which features an exceptional fluidity and good operability. When mixed with 2%-3% curing agent, they can still be operated within 30 minutes, but will be formed after 2-3 hours. With resistance to deformation, high temperature, acid and alkali, and expansion, silicon flexible molds are used for mold duplication and delicate mold making for poly crafts, resin crafts, lighting and candle crafts.
Silicone RTV-2 for mold making is a white or red flow able liquid with a hardness of 22-50A when cured. If large products and therefore multiple-piece molds are needed by customers, silicon rubber higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be needed for speedy drying and fast release and less when otherwise.
