Rubber raw material silicon

1.Good flowability and long working time 2. Medium hardness 3. High tear and tensile strength 4. Easy de-mould

 APPLICATIONS

MC Silicone RTV2 series are suited for reproduction of cement molding, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. Etc.

 DESCRIPATION

MC Silicone RTV2 mold making rubber is a two-component material, consisting of Part A base silicone and Part B CA30 curing agent, cures 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..
