 DESCRIPATION

MC Silicone RTV2 mold making rubber is a two-component material, consisting of Part A base silicone and Part B CA30 curing agent, cures at room temperature by a condensation reaction. These materials can be cast into the cured silicone mold: plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc..

APPLICATIONS

MC Silicone RTV2 series are suited for reproduction of cement molding, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. Etc.

Procedures

 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

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

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

Note:

RTV2015/RTV2040 is an industrial product and must not be used in food molding, dental human skin molding applications
