Description of RTV-2 silicone

 

RTV-2 Silicone is a kind of two-component material. The silicone rubber is made up of Part A base silicone and Part B curing agent. The Part A base silicone and Part B CA curing agent can cure at room temperature by a condensation reaction, after full cure, it become a cured silicone mold. The silicone mold can be cast the following materials for reproduction: plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc...

 

Characteristics of RTV-2 silicone   

 

1. Good flow ability and long working time

 

2. Medium hardness

 

3. High tear and tensile strength

 

4. Easy de-mould from complex replica parts

 

5. Acid and alkali-resistance

 

6. Low linear shrinkage
