Product Information
Model NO.: C-825 and C-830
Hardness: 25, 30 Shore A
Mixing Ratio: 100:2
Keyword: mold making silicone rubber, rtv 2 silicone rubber, liquid molding silicone
1.Description
silicone mold rubbers can also be used for wax, plaster and concrete casting, but are most beneficial for high volume resin or foam casting. Release agents are generally not needed for casting any of these materials, which is why they are sometimes preferred over polyurethanes. For resin sculptures that need to be painted after casting, silicone mold rubbers are recommended.
The popular silicone for these fields is C-825/C-830, medium hardness, tin-cured silicone rubber with a 100A:3B mix ratio (digital scale required for measuring) and 3-4hour demold time. Can easily be thickened with Liquid Thickener for brush-on application.

Hardness | Shore A | 25±2 | 30±2 |
Mix Ratio | A:B | 100:3 | 100:3 |
Color | / | White | White |
Pot life | 25 °C (77F) | 30-40mins | 30-40mins |
Curing time | 25 °C (77F) | 3-4 hours | 3-4 hours |
Mixed viscosity | mPa.s | 20000±1000 | 23000±1000 |
Tear-strength | kg/cm | 22±2 | 23±2 |
Tensile-strength | M.pa | 4.0±0.5 | 5.0±0.5 |
Elongation | % | 450±50 | 460±50 |
Shrinkage | % | ≤0.3 | ≤0.3 |
Note: This is a 100A:3B mix ratio product that must be measured by weight. The choosing of suitable hardness should be according to the size and pattern design of the products. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be added for speedy drying and fast release and less when otherwise.

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.
