Description of RTV Silicone for Making Candle
LSR ( Liquid Silicone Rubber ) for Candle 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 Silicone for Making Candle
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 Silicone for Making Candle
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 RTV Silicone for Making Candle
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.
