Product Description

Description of Liquid Silicone Rubber for Plaster Decoration Molding

Liquid 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 Liquid 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 Liquid Silicone Rubber

Liquid silicone rubber for mold making can be applied in many objects mold making, since MC liquid silicone rubber has good flow ability and medium hardness, and the silicone can cure at room temperature, thus it's a good material for duplication.

RTV-2 Silicone Rubber can be used for artificial stone moldmaking. For example MCSIL-2066 and MCSIL-2088 silicone.

RTV-2 silicone rubber can be appliied in candle and soap moldmaking, such as MCSIL-215 and MCSIL-218 silicone.

RTV-2 silicone rubber can be used for plaster moldmaking, such as MCSIL-M25, MCSIL-H25 and MCSIL-M30 silicone.

RTV-2 silicone rubber can be applied in the field of shoe sole moldmaking, for example, MCSIL-S10 and MCSIL-S15 silicone.

RTV-2 silicone rubber can be used for prototyping and electronic potting.


How to make the silicone mold?

1. Make sure the surface of the original is clean and free of loose material.
2. Weight 100 Part A base and 2 parts of CA30 Curing Agent in a clean container.
3. Stir Part A base silicone before use thoroughly, as filler separation may occur upon prolonged storage.
4. Mix Part A and Part B evenly until the CA30 completely dispersed in the base.
5. Pour the mixed Part A base silicone and CA-30 curing agent as soon as possible onto the original
6. De-mold after 24 hours, it is will improve the replicate times of silicone mold.
Note: It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. After a further 1-2 mins under vacuum, the mix 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.

Packing of Liquid 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 Liquid Silicone Rubber

When the liquid 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 Liquid Silicone Rubber

RTV2 silicone rubber is an industrial product and must not be used in food molding, dental human skin molding applications.
