Users Instructions of silicone rubber for mould casting
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%to 5% curing agent, they can still be operated within 40~70 minutes, but it will be formed after 4-5 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.
This product is a white or red flowable liquid with a hardness of 23to 25 shore A° When it gets cured. For molds making of large-sized products, multiple-piece molding methods is required. Meanwhile you will need silicon rubber with a higher hardness. Conversely, soft silicon is indispensable for molds with complicated patterns and delicate details. The amount of curing agent admixture depends on your requirements. Pls add more for a speedy drying process and a fast releasing and less on the other hand.
