Product Description

Introduction

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. Generally, RTV-2 Silicone Rubber is a kind of two-component material. The RTV-2 silicone rubber is made up of Part A base silicone and Part B curing agent. The Part A base silicone and Part B CA curing agent can cure at room temperature by a condensation reaction, after full cure, it become a cured silicone mold. The silicone mold can be cast the following materials for reproduction: plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc...

Characteristics

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 used 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.
