Application:
GC RTV silicone G-8 series are great for artificial stone casting. They are widely used for architectural elements, block-outs & hole former, concrete counter tops, flexible form liners, GFRC, manufactured stone veneer, ornamental precast & statuary, stamped & textured concrete, etc.
Operation Method:
Both pouring and brushing operation methods for our artificial stone casting silicone are available. You can choose the best one as your preference, we can provide thixotropic agent for brushing.
Notice
What is the hardness should I choose?
Normally 20~40 Shore A will be the best, but it also should according to your size and pattern design.
Warm Tips:
The surfaces with which the material comes in contact must be perfectly clean, free of grease and dry.
Close the bottles after use so as not to confuse the cap of the catalyst with that of the base when re-sealing.
Be aware of possible cross-contamination; it's highly recommended to use only dedicated gear when processing poly-addition RTV2 silicone rubber (including degassing devices).
Be aware that contact with certain material can inhibit the curing of the RTV2 poly-addition silicone rubber. Common contaminants to be avoided include:
-Natural or synthetic rubber, vulcanized with sulphur derivatives.
-Poly-condensation RTV catalyzed with metallic salts.
-PVC stabilizing agents.
-Amine cured epoxies.
-Sulphur, tin and amines derivatives.
-In case of doubt, carry out a small test by pouring the mixture onto a small area of the object.

We offer superior quality sponge iron that is also known as direct- reduced iron. Our offered sponge iron is made for high grade, 65-70 fe Min fem-80%, fet-90-92%, s-0.04% max. Loose in form of lumps. Sponge iron filter material In industry through a sponge iron production equipment is widely applied iron phosphorus reduction method, method of reduction of iron ore concentrate, etc., the rolling iron phosphorus or ore concentrate after reduced iron press down into pieces, into the roasting tube into the kiln roasting, produce the high quality reduced iron. Sponge iron filter material for the first time into the deaerator, must first after backwashing, remove the sponge iron residue on the surface of the filter material float ash impurities.
