RTV-2 silicone Liquid is generally named as two-part room-temperature vulcanized silicone rubber, which features exceptional fluidity and good operability. When mixed with 2-3% curing agent, they can still be operated within 30-40 minutes, but will be formed after 4-6 hours. With resistance to deformation, high temperature, acid and alkali, and expansion.
PRODUCT FEATURES
1. Good flow ability and long working time
2. Excellent performance for duplication
3. High tear and tensile strength
4. Easy de-mould from complex replica parts
5. Acid and alkali-resistance
6. Low linear shrinkage

USING INSTRUCTION
1-Take 100g of part A and add 2g of part B catalyst and mix the silicone rubber and curing agent evenly in the container stirring and making sure not to incorporate air..
2-vacuum pumping may be applied
3-Pouring into a mold or block mold of silicone rubber
The pouring way is an easy way such as a long treacle to fill molds, it’s slowly . Allow to set.
