Product Description

Description of RTV Silicone Rubber for Soap Mold Making

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

Specifications of RTV Silicone Rubber for Soap Mold Making

1. Good flow ability and long working time
2. Low hardness, easy de-mold
3. High tear and tensile strength
4. Acid and alkali-resistance
5. Low linear shrinkage

Applications of RTV Silicone Rubber for Soap Mold Making

MCSIL-215/218 silicone rubber is suited for middle size reproduction of candle mold, soap mold, small size concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, and the products with thin flower patterns.

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 to 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.

Storage of RTV Silicone Rubber for Soap Mold Making

When the silicone rubber is stored at or below 30C (85F) in the original unopened containers, RTV215-218 silicone base and curing agent have a usable life of 12 months from the date of production.

Note of RTV Silicone Rubber for Soap Mold Making

MCSIL-215/218 silicone rubber is an industrial product and must not be used in food molding, dental human skin molding applications.

Packing of RTV Silicone Rubber for Soap Mold Making

Part A base silicone: 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 0.25kg/bottle, 1kg/bottle and 10kg/bottle
