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..
RTV2 condensation silicone rubber,RTV2 mold making silicone rubber, Room temperature curing silicone, pad printing silicone, manual mold making, crafts mold making, shoe mold making, it can be used for candle, soap, toys crafts, cement, gypsum, concrete, PU resin, poly resin, furniture, decoration, architectural moulding, lighting, stationery, Statues, artificial stone mold making, etc.

How to make the silicone mold?
l The surface of the original should be clean and free of loose material. If your products with thin flower patterns, and especially with porous substrates, please use a suitable mold release agent such as soap water, detergent, Vaseline or petroleum jelly.
lPlease weight 100 Part A base and 2 parts of CA30 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 CA30 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.
l Pour the mixed Part A base silicone and CA-30 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.
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
