Introduction of Liquid RTV Silicone Rubber for Plaster Crafts 

Liquid RTV Silicone Rubber is a kind of two-component material, this kind of silicone rubber consists of Part A base silicone and Part B CA30 curing agent, when mix the base silicone and curring agent in a ratio(100:2;100:5;100:10;100:100)and Part A base silicone and Part B curing agent can cure at room temperature by a condensation reaction. These following materials can be cast into the cured silicone molds: plaster polyurethane, PU, GRC, cement, resin, polyester, wax etc...

Applications of Liquid RTV Silicone Rubber for Plaster Crafts 

Liquid RTV Silicone Rubber can be also applied in the field of reproducing cement molding, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. Etc.

Instructions for Liquid RTV Silicone Rubber for Plaster Crafts 

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.

Storage of Liquid RTV Silicone Rubber for Plaster Crafts 

When the Liquid RTV Silicone Rubber is stored at or below 30 °C(85 °F) in the original unopened containers, RTV Silicone Base and CA30 Curing agent have a usable life of 12 months from the date of production. After 12 months,please use a stirring mill to stir the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.

FOQ of RTV-2 Silicone Rubber for Mold Making

Why does the RTV liquid silicone rubber for molding have few mold making times?

The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.
