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.

Company introduction: GUOCHUANG SILICONE CO., LTD. has manufactured condensation cure (tin-catalyzed) and addition cure (platinum- catalyzed) RTV-2 (Room Temperature Vulcanized - 2 components) silicones since 2003. We have the formulating and manufacturing expertise to produce custom RTV-2 silicones for a variety of applications. We have earned a sterling reputation for innovation, quality and consistency in a wide range of industries.
RTV-2 silicone rubber is used primarily in the mold-making industry. Silicone molds are durable, simple to construct and use, and suitable for most casting materials.
RTV-2 silicone rubber is used in the electronics industry for potting and encapsulation. Silicones used to encapsulate electronic parts must maintain their properties over a wide range of temperatures and environmental conditions.
RTV-2 silicone rubber is used in the movie, entertainment and special effects industry to create scenes and characters that come alive on the big screen, television and in theme parks. Soft “skin” silicone rubbers, used by make-up and Fx artists, were developed specifically at the request of special effects studios.
GUOCHUANG's collective mission is to design and manufacture the highest-performance line of liquid silicone rubbers and related casting products and to provide our customers with unmatched, industry-setting technical support and customer service. In doing so, we are committed to helping our customers realize the greatest value from the use of our products and resources.
