The Gedeo Siligum Molding Paste is an ideal solution for crafters, jewelers, and artists looking to create precise, flexible molds for small objects and flat decorations. Its key advantage is the fast-setting, two-component silicone formula that captures intricate details and allows for efficient demolding. However, it is primarily designed for small-scale applications, so consider its size limitations for larger projects.

Info needed: The product description does not specify food-grade compliance. It is generally advised not to use molding compounds for food items unless explicitly stated by the manufacturer.
Gedeo Siligum is fast-setting, typically curing within a few minutes. Always refer to the product packaging for the most precise curing time, as it can vary slightly.
Gedeo Siligum is designed for small objects and flat decorations. While technically possible, making very large molds might be cost-prohibitive and challenging due to the short working time and quantity needed. Consider other molding materials specifically designed for larger projects.
With proper care and depending on the casting material and complexity of the cast, Siligum molds are highly durable and can be reused many times.
For non-porous objects (like metal, plastic, polished wood), a release agent is generally not required. For porous objects (e.g., unsealed wood or plaster), it's recommended to apply a suitable release agent to prevent the Siligum from sticking.
Info needed: Always check the product packaging for the specific shelf life. Generally, sealed two-component silicone pastes have a shelf life of several months to a year when stored correctly in a cool, dry place. Once opened, it's best to use them within a shorter timeframe.
This usually indicates improper mixing. Ensure equal parts of components A and B are used, and knead them thoroughly until the color is completely uniform. Temperature can also affect curing; ensure room temperature is appropriate (not too cold).
Press the mixed paste firmly onto the original object, starting from one end and working your way across, to push out trapped air. Avoid rapid, aggressive kneading, which can introduce air bubbles.
Ensure the mold is fully cured before attempting to demold. For very intricate or delicate original objects, consider creating a two-part mold to reduce stress during removal.
Ensure the paste is pressed firmly and uniformly over the entire surface of the original object, especially into intricate areas. Check the original object for any residues that might prevent proper contact.
