Condensation Cure Two-part Silicone Liquid Rubber for Making Manufactured Stone Molds
Silicone liquid rubber is called Tin cure silicone rubber which is also called condensation-cure silicone mold rubber, these are high-tear silicone mold rubbers that are known as the “work horse” of the industry because of their performance and economy. Tin cured silicone molds are used for casting wax, cement, gypsum, polymer modified gypsum, resins, etc.
Applications of Liquid silicone rubber:
1- Liquid silicone rubber for molding is mainly applied for making various molds:
2- Liquid silicone rubber for molding can used to reproduce concrete or cement, gypsum, gypsum, architecture, decorative arts and crafts, big statue, cultural relic product, etc.
3- Liquid silicone rubber for molding can used to reproduce poly resin, epoxy, polyurethane-polymer, plastic toy, gift and stationery.
4- Liquid silicone rubber for moldingcan also used to reproduce soaps, candle & lighting.

Instruction of RTV-2 silicone liquid rubber:
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.
Why RTV-2 Silicone Liquid Rubber?
As the most stable polymer available, silicones offer superior reliability, excellent service life and reduced production costs.
Silicone rubbers cure in deep sections as needed for electrical potting and encapsulating, casting rubber parts, arts restoration, general handy crafts, lost wax casting process, plaster forms, seals, stage decorations, statuettes and many more.
Silicones resist acids, bases, solvents, chemicals, oils and water.
Package of RTV-2 Silicone Rubber
Part A base silicone: 20kg,25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 800g/bottle, 1kg/bottle
Storage and Precautions of silicone liquid rubber:
RTV-2 silicone rubber for making art crafts, which is an environmentally-friendly liquid silicone product, is not easy to burn and can be stored and transported as non-hazardous goods. The shelf life of the product is about one year from the date of production. Inspection is required when exceeding the time limited. It can continue to be used in case of neither thickening nor deterioration.
