Gedeo Siligum Moulding Compound - PEBEO

Gedeo Siligum is a fast-setting compound that cures in just a few minutes after the two components are thoroughly mixed.

You can cast a wide range of materials, including various resins (epoxy, polyester), plaster, waxes, traditional clay, polymer clays like FIMO, metal clay, and even low-melting point metals.

Yes, Gedeo Siligum creates flexible and durable silicone molds that are designed for multiple uses, providing long-term utility.

Gedeo Siligum is specifically formulated for creating molds of small objects with fine details and flat decorations. It is not recommended for large-scale molding projects.

Always take equal parts of component A and component B. Knead them together vigorously and thoroughly for about 30-60 seconds until a completely uniform color is achieved, with no streaks of either original color visible.

Store both components separately in their original, tightly sealed containers in a cool, dry place, away from direct sunlight and extreme temperatures, to prevent premature curing and maintain shelf life.

> Info needed: The product description does not specify if Gedeo Siligum is food-safe. It is generally recommended to avoid using craft molding compounds for food-contact applications unless explicitly stated by the manufacturer.

For future molds, mix the compound slower to avoid incorporating air and press it firmly and carefully onto the object, working from one side to the other. For existing molds, minor imperfections might be carefully trimmed if they don't affect the cast.

Ensure exact equal parts of both components were mixed thoroughly. Incomplete mixing or incorrect ratios are the most common causes. Knead vigorously until a uniform color is achieved. Check ambient temperature; very cold environments can slow curing.

Ensure the original object was completely clean and dry. When applying the mixed compound, press it firmly and evenly around the object to eliminate air pockets and ensure intimate contact with all details.

Mix the two components slowly and deliberately to avoid incorporating excess air. When pressing onto the object, start from one side and roll it over, or press firmly from the center outwards to push air away.

Ensure the mold is fully cured before attempting to demold. While flexible, sudden, forceful pulling can damage intricate details. Gently flex the silicone mold to release the object or cast.

Avoid overstretching or sharp bends, especially with delicate molds. If repeatedly tearing, consider if the mold design is too thin in certain areas or if the casting material is adhering too strongly (though rare with silicone). Ensure the mold has fully cured and is not still soft.
