Clear Liquid Silicone is an addition cure (platinum-catalyzed) silicone rubber compound. It consists of two parts: Part A, a thicker viscous base, and Part B, a colorless platinum curing agent with a water-like consistency. When mixed in a weight ratio of 10A:1B, the compound can cure at room temperature or faster at slightly higher temperatures.

Once cured, clear liquid silicone forms a flexible and elastic material that boasts high transparency, high tear strength, and extremely low shrinkage. Because of these properties, clear liquid silicone is an excellent choice for making molds that require intricate details and precise tolerances.

Curing Principle: The curing of clear liquid silicone is greatly affected by temperature. This is because the viscosity of clear silicone is relatively high, making it difficult for molecules to bond together. Temperature is necessary to activate the reaction between the silicone and the curing agent. As the temperature increases, the platinum catalyst becomes more active, resulting in a faster cure.

Application Examples

Clear Liquid Silicone is particularly suitable for creating molds where model visibility is crucial, such as in jewelry making and prototyping. Its transparent nature makes it easy to extract the model from the mold through cutting or other methods. Because of its fine precision and excellent transparency, clear liquid silicone is typically used to create complex and high-grade jewelry and other luxury items.

Clear liquid silicone is commonly used for casting epoxy, creating artificial jewelry, crafting crystal jewelry, and producing high-quality crafts. Its unique properties make it an excellent choice for these applications, allowing for intricate details to be captured while maintaining transparency.

Clear liquid silicone is a highly durable material that creates strong, tough, and tear-resistant molds. It is perfect for creating complex molds that require precise detail, difficult undercuts, spirals, and cores.

Attention

It is recommended to perform a small test application to assess the suitability of the clear liquid silicone for your specific project.

It is important to use the part A base and part B catalyst that are provided together in the same kit. Mixing different brands of hardener with silicone may result in the mixture not curing properly.

Clear liquid silicone has a relatively high viscosity compared to other silicone types. To achieve a clear silicone mold without any trapped air bubbles, it is recommended to degas the mixture.

It is important to avoid contact with water, impurities, smoke, organotin catalysts, acids, bases, and other substances containing sulfur, phosphorus, nitrogen, or organic compounds. These substances can inhibit the curing process of the silicone mixture.

It is not recommended to cure the clear liquid silicone at temperatures below 20°C (68°F), as it may lead to a reduction in the final cure hardness and physical properties of the material. Below 15°C (60°F) the clear liquid silicone will be difficult to cure.

Curing silicone at room temperature helps minimize shrinkage. If a faster cure is desired, gentle heat can be used. It is recommended to cure the rubber for 2-3 hours at 40-60°C (104-140°F).

To achieve the best possible transparency in the mold, it is advisable to maintain the maximum thickness of the mold walls at 20mm or less.

Safety

Clear liquid silicone rubber is considered a safe and non-toxic material. Therefore, there are no special treatment precautions required when using it. However, if you choose to wear gloves during the handling and application process, it is recommended to use vinyl gloves. Latex gloves should be avoided as they can interfere with the curing process of the silicone rubber.

It is important to note that our clear silicone product has not been tested or represented as suitable for medical or pharmaceutical uses. While the material is safe and non-toxic, it is not recommended for use in these applications due to potential compatibility issues or other factors that could impact performance or safety.

Caution: Avoid splashing product into eyes. In the event of contact, rinse eyes thoroughly with plenty of water and seek medical attention immediately.

Adult supervision is required when using this product, and it should be kept out of the reach of children.
