Silicone Rubber, Packaging Type : white

We are offering rtv-2 silicone rubber for candle mold making.
Description
rtv-2 silicone rubber 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 silicone rubber materials can be cast into the cured silicone mold: plaster, polyurethane, pu, grc, cement, resin, polyester, wax etc.
specifications
1. Good flow ability and long working time
