When working on small castings or projects where resin is poured in layers under 2cm, selecting an epoxy formulated for thin applications is key to achieving a flawless and long-lasting result.
Recommended Epoxy Resins for Thin Castings
For most projects involving layers under 2cm, such as art, woodworking inlays, or decorative crafts, Trasparente epoxy resin is a top choice. It is specifically designed for use up to 2cm thick, offering a clear finish and strong UV protection. Its low viscosity helps bubbles dissipate for smooth, glassy results.
- Trasparente: Best for general thin castings, art, and furniture
- Icrystal: Ideal for superfine layers up to 1.5cm, especially in jewellery, surface coatings, and projects where minimal odour is preferred
- EpoxyFood: Certified food-safe, suitable for thin coatings on kitchenware or items in contact with food
How to Achieve the Best Results
To minimise the risk of overheating and ensure clarity:
- Stick to the manufacturer’s recommended maximum thickness per pour (usually 2cm for Trasparente, 1.5cm for Icrystal).
- Work in a cool, well-ventilated space and avoid direct sunlight while curing.
- Mix gently according to instructions and pour slowly to reduce trapped air.
- Avoid using heat guns or hot water baths to accelerate curing, as this can cause excessive exotherm in thin applications.
When Thin Casting Matters
Choosing the correct resin for projects below 2cm is crucial when clarity, surface finish, and safety are priorities—especially for pieces with fine detail, layered colours, or food contact surfaces.
