Platinum Cure liquid molding Silicone Rubber for rapid Prototyping

Platinum Cure liquid molding Silicone Rubber for rapid Prototyping

Prototyping Silicone

Features

Application:

GC RTV silicone G-8 series are great for prototyping. Rapid prototyping is a method to create a original model or functional parts quickly from your design to an real item. When you draw a CAD and create a new model by stereo lithography or other 3D printing process, it can be duplicated by prototyping silicone to make a mold and cast parts. Now, the prototyping silicone is wildly used for car model, toy model, part model, plane model, molding, etc.

Operation Method:

Both pouring or brushing operation methods for our rapid prototyping molding silicone are available. You can choose the best one as your preference, we can provide thixotropic agent for brusing.

Appearance

Part A: a non-toxic and odorless liquid with translucent color and platinum inside.

Part B: a non-toxic and odorless liquid with translucent color.

ATT: We can do any curing time as your requirements.

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.
