Description of Sculpture Mold Making Silicone Rubber

RTV-2 silicone rubber is a two-component material, this kind of silicone rubber consists of Part A base silicone and Part B CA30 curing agent, and Part A base silicone and Part B curing agent can cure at room temperature by a condensation reaction. These materials can be cast into the cured silicone molds: Plaster polyurethane, PU, GRC, cement, resin, polyester, wax etc...

Features of Sculpture Mold Making Silicone Rubber

1. Good flowability 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 of Sculpture Mold Making Silicone Rubber

RTV2030 silicone rubber is suitablr for plaster, statues, sculpture and GRC mold making.

How to make the silicone mold?

1. Preparing

The surface of the original objects should be clean and free of loose material. If your products have thin flower patterns, and especially have porous substrates, please use a suitable mold release agent such as soap water, detergent, Vaseline or petroleum jelly.

2. Mixing

Please weigh Part A silicone base and part B CA30 Curing Agent with ratio of 100: 2 into a clean container. Stir Part A base silicone thoroughly before use, then Mix Part A and Part B evenly until the curing agent completely dispersed in the silicone base. Manual or mechanical mixture can be used, but do not last much time or allow the temperature to exceed 35C (95F). It's suitable to mix small quantities to ensure thorough mixture of silicone base and curing agent.

Note: It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mixture to completely expand and then collapse. After a further 1 to 2 minutes under vacuum, the mixture should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen.

3. Pouring the mixture and curing

Pour the mixed Part A base silicone and CA-30 curing agent as soon as possible onto the original object, avoiding air entrapment. The catalyzed material will cure to a flexible rubber within 6 hours (or faster by different mixing ratio or room temperature), we advice you de-mold after 24 hours, it is will improve the replicate times of silicone mold.

Packing of Sculpture Mold Making Silicone Rubber

Part A base silicone: 20kg/drum, 25kg/drum or 200kg/drum

Part B CA30 Curing Agent: 0.25kg/bottle, 1kg/bottle and 10kg/bottle

Storage of Sculpture Mold Making Silicone Rubber

When the RTV-2 silicone rubber is stored at or below 30 C (85F) in the original unopened containers, Silicone Base and CA30 Curing agent have a usable life of 12 months from the date of production.

Note of Sculpture Mold Making Silicone Rubber

RTV2030 silicone rubber is an industrial product and must not be used in food molding, dental human skin molding applications.
