Product Description

Description

RTV-2 is a two-component Room-Temperature-Vulcanizing (RTV-2) silicone rubber. Depending on its curing mechanism, two types of RTV-2 are available: "condensation" cure type and "addition" cure type.As a kind of two-component material, MC RTV-2 silicone rubber for mold making is composed of Part A base silicone and Part B CA curing agent. Because a condensation reaction, the Part A base silicone and Part B CA curing agent can cure at room temperature, and become a cured silicone mold. Then the silicone mold can be poured the material below to duplication: plaster polyurethane, PU, GRC, cement, resin, polyester, wax etc...

Specifications

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

6. Low linear shrinkage

Applications

RTV-2 silicone rubber for mold making can be applied in the filed of reproducing cement molds, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. Etc.
