Product Description

Product Description

Our RTV-2 Liquid Silicone Rubber is a two component RTV-2 silicone specifically formulated for manufacturing high precision molds for statues, sculptures, art replicas, and decorative objects. This professional grade mold making silicone is designed for casting plaster, gypsum, concrete, GRC, polyurethane resin, polyester resin, wax, and cement.

RTV-2 silicone rubber is widely used in sculpture and statue mold making due to its excellent release properties, high tear strength, and detail reproduction capabilities. The material can be used for virtually any reproduction material, from plaster and wax to concrete and even low-melting metals

Key Features

Optimized for Statue and Sculpture Casting - Formulated to capture the finest details of sculptures, including facial features, fabric folds, textures, and complex geometries. Compatible with plaster, gypsum, concrete, GRC, resin, wax, and cement.

High Tear Strength - Tear strength of 20 to 30 kN m ensures molds withstand repeated demolding of rigid castings without tearing.

Low Shrinkage - Ultra low shrinkage of 0.1 to 0.3 percent ensures dimensional accuracy and consistent reproduction of original sculptures.

Excellent Detail Reproduction - Low viscosity formulation flows smoothly into every cavity capturing fine details including fingerprints, textures, and complex surface patterns.

Easy Demolding - Inherent non stick surface allows cured casts to release cleanly without release agents.

Room Temperature Curing - Vulcanizes at room temperature within 4 to 12 hours. No heating equipment required.

Adjustable Hardness - Shore A hardness from 15 to 40 customizable to meet specific requirements

ADDITIONAL INFORMATION
Reproduction of Vertical Surfaces
If a skin mold is required of a vertical object or surface and cannot be made by normal pouring techniques, the catalyzed mixture can be made non flowable by the addition of thixotropic agent.

1. Prepare the original as described earlier.
2. Brush the original with a thin layer of catalyzed mixture. Repeat the operation when the first layer has started to cure, to achieve a coating thickness of >2mm. Leave to cure at
room temperature until the material is tacky.
3. Prepare a new catalyzed mixture of silicone and add 1% by weight of thixotropic additive and mix thoroughly until a paste consistency is reached. De-airing of the mixture is not
required.
4. Using a spatula, cover the coated original with the thixotropic coating until all undercuts are filled; leave to cure for 24 hours at room temperature.
5. Construct a support mold using polyester resin or plaster and allow to set in contact with the silicone coating. Carefully remove the support mold. Peel the rubber off the original
and place in the support mold.

Use at High Temperatures
Some molds produced from condensation cure silicone rubbers can degrade when exposed to temperatures above 150°C (302°F) over a period of time or when totally confined in
storage at high ambient temperatures. This can result in softening and loss of elastic properties.
Resistance to Casting Materials
The chemical resistance of fully cured silicone rubber is excellent, and similar to all condensation cure silicone elastomers. It should be noted however that ultimately, resins and
other aggressive casting materials will attack silicone molds, changing physical properties, surface release and possibly mold dimensions. Molds should be checked periodically during
long production runs.
