This particular product is a type of Silicone that cures with tin/condensation and is designed to be a high-quality material that is flexible, elastic, and has exceptional strength against tension and tearing. It has minimal shrinkage (0.2%) and can accurately replicate fine details. The Silicone has a long lifespan for molds and is easy to release from them. It is ideal for casting a variety of materials, especially casting resins which are also available for purchase. Examples of suitable casting materials can be found at the end of the listing.
The product comes in a three-part kit consisting of a white base Silicone, a color catalyst for visual identification to ensure thorough mixing, and a thixotropic additive that thickens the liquid silicone, making it suitable for application with a brush or spatula to create glove moulds . A clear catalyst is also an option if preferred.
Health concerns have been taken into consideration, and the catalyst is non-toxic, non-flammable, and nearly odorless compared to other condensation-cure silicones that may use toxic catalysts.
There are two options for hardness:
soft and medium.
The soft option is better for moulding delicate, fragile items where the Silicone needs to be soft and flexible to prevent damage to the castings. The medium option is suitable for most cases.
For optimal results, it is recommended to apply an initial coat of unthickened or slightly thickened silicone to capture fine details and prevent air bubbles on the mould’s surface. After the initial coat, multiple thicker layers can be applied at any stage of curing. Typically, the thixotropic additive is added in amounts ranging from 0.1-3% by weight, depending on the desired consistency. It can be added before or after the catalyst. To determine the appropriate consistency, it is advised to add a small amount of the thixotropic additive to the Silicone, mix thoroughly, and observe its flow characteristics. Repeat this process until the desired consistency is achieved, especially for beginners who may need more time to get it right before adding the catalyst.
It is important to note that this product is not safe for use with food. For food-safe alternatives, please click here.” The catalyst in this product can cause skin irritation, which is why it is not recommended for direct application to human skin for life casting.

This type of Silicone is condensation/tin cured, so it cannot be used as a mold for addition/platinum cured silicone Silicones as it will affect the curing process.
For creating a two-part mould or moulding a glass object, a release agent is necessary..
