Introduction of Liquid silicone rubber:

1- Liquid silicone rubber for molding is a two-part silicone rubber for molding: flowable liquid silicone and catalyst.
2- Liquid silicone rubber for molding cures at room temperature within 4-6 hours.

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.

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?

Economic Use
As the most stable polymer available, silicones offer superior reliability, excellent service life and reduced production costs.

Versatile Application
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.

Chemical Resistance
Silicones resist acids, bases, solvents, chemicals, oils and water.
