RTV 2 Condensation Cure Liquid Molding Silicone Rubber For Cultured Stone Molds
Description of RTV 2 condensation cure liquid molding silicone rubber for cultured stone molds
RTV 2 mold making rubber is a two-component material, consisting of Part A base silicone and Part B C520 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.
Features of RTV 2 condensation cure liquid molding silicone rubber for cultured stone molds
lGood flow ability and long working time
lMedium hardness
lHigh tear and tensile strength
lEasy de-mould from complex replica parts
lAcid and alkali-resistance
lLow linear shrinkage

How to make the silicone mold?
Please weight 100 Part A base and 2 parts of B the Curing Agent in a clean container. Thoroughly stir Part A base silicone before use, as filler separation may occur upon prolonged storage. Mixing Part A and Part B evenly until the curing agent completely dispersed in the base. Hand or mechanical mixing can be used, but do not for an extended period of time or allow the temperature to exceed 35C (95F). Mix suitably small quantities to ensure thorough mixing of base and curing agent.
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 minutes 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.
Pouring the mixture and curing
Pour the mixed Part A base silicone and part B the curing agent as soon as possible onto the original, 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.

Storge of RTV 2 condensation cure liquid molding silicone rubber for cultured stone molds
When stored at or below 30 C(85F) in the original unopened containers, silicone rubber Base and part B the Curing agent have a usable life of 12 months from the date of production. After 12 months stock, pls use the Stir to mixing the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.
