Silicone Liquid Rubber for Candle Mold Casting/Liquid Silicone Rubber

Description of silicone rubber for candle mould making, liquid silicone

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 silicone rubber for candle mould making, liquid 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

Note of Liquid RTV Silicone for Candle Mold Making

RTV215/218 silicone rubber is an industrial product and must not be used in food molding, dental human skin molding applications.

Packing of Candle Mold Making Liquid Silicone

Part A base silicone: 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 0.25kg/bottle, 1kg/bottle and 10kg/bottle
