RTV TWO 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 3% to 5% 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 poli crafts, resin crafts lighting and candle crafts.

This product is a white or red flowable liquid with a hardness of 22 to 50A° when cured. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with 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 added for speedy drying and fast release and less when otherwise.

(Note we do not recommend silicon oil. For special soft mold or molds with complex pattern or fine details, 5% to 10% silicon oil can be added to condition the flexibility of the mold for convenience of release)
