Product Description
 Silicone Rubber for concrete casting

 silicone rubber application:
1. Silicone Rubber can used for poly resin crafts, PU crafts, PU resin crafts, gypsum crafts, unsaturated resin crafts, lighting and candles crafts, plastic toy, stationery gifts crafts industry.

2.Silicone Rubber is applicable for large statue Buddha, relievo furniture, furniture decorative materials, statues Buddha, artifacts copied, building decoration materials, large-scale cement mold.

silicone rubber features:
RTV silicone rubber, silicone rubber are generally named two -component room temperature vulcanization silicone rubber, a kind elastic silicone rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion.

Advantages of Silicone rubber:
RTV Silicone rubber as useful as latex, but sets a lot more quickly. RTV Silicone rubber can take days to build enough layers of latex to create a mold, but RTV Silicone rubber can be mixed, poured and set within a matter of hours, even minutes depending on what kind of silicone you use. Silicone is generally a lot stronger than latex and will produce more castings on average.


 silicone rubber instructions:
Add curing agent of 2%-3% at the room temperature, the silicone rubber is still operational within 30 minutes, and in 2-3 hours, an elastic silicon mold will be obtained with resistance to deformation, high-temperature, acid and alkali and expansion.
