Description of RTV-2 Silicone soap molds making 

 

RTV-2 Silicone Rubber for soap Mold Making is a two-component material, which consists of Part A base silicone and Part B CA30 curing agent; then the silicone base and curing agent can cure at room temperature by a condensation reaction. These materials can be cast into the cured silicone mold: plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc.

 

Characteristics of RTV-2 Silicone soap molds making            

 

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

Applications of RTV-2 Silicone soap molds making        

 

 

RTV-2 Silicone rubber is suited for middle size reproduction of candle mold, soap mold, small size concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, and the products with thin flower patterns. 

 

RTV215 and RTV218 silicone is especial suitable for candle and soap mold making

 

 

 

 Storage of Silicone Rubber for Candle Mold         

 

When the Silicone Rubber for Candle Mold Making is stored at or below 30 °C(85 °F) in the original unopened containers, RTV-2 Silicone Base and CA30 Curing agent have an usable life of 12 months from the date of production. After 12 months,please use a stirring mill to stir the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.
