Product Description
General decription of RTV-2 silicone for casting stone molds

RTV-2 silicone for casting stone molds is generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2% curing agent, they can still be operated within 30 minutes, but will be formed after 4-6 hours. With resistance to deformation, high temperature, acid and alkali, and expansion, silicon flexible molds are used for mold duplication and delicate mold making for poli crafts, resin crafts lighting and candle mold, etc.

Features of RTV-2 silicone for casting stone molds

(1)high tensile & tear strength
(2) Low linear shrinkage
(3)free Curing agent
(4)brushing & pouring
(5) high duplication times

Operation instructions of RTV-2 silicone for casting stone molds

Correct mixing ratio
Component A is silicone rubber, and component B is curing agent or vulcanizing agent. Usually the mixing ratio will be 2-3%, e. G. To 100g silicone rubber should be added 2g catalyst and then mix them thoroughly. (Note: The weight of the silicone and catalyst should be weighed correctly).

Pouring the mixture and curing

Pour the misxed 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.

Storage and Precautions of RTV-2 silicone for casting stone molds

RTV-2 silicone for casting stone molds is an environmentally-friendly liquid silicone product, is not easy to burn and can be stored and transported as non-hazardous goods.
