If you’re planning a casting project that requires a resin depth of more than 5 cm, selecting the right epoxy is crucial. Standard casting resins often face challenges with heat and bubble control at this thickness, so it’s important to use a formulation specifically designed for deep pours.
Choosing the Right Resin for Deep Casts
Not all epoxy resins are suitable for thick castings. For pours above 5 cm, specialised deep-pour resins offer a lower exothermic reaction to prevent overheating, which reduces the risk of yellowing, cracking, or deformation. “Epoxytable 10-Ten” is specifically designed for this purpose, supporting single-layer pours up to 10 cm thick. Its formulation ensures excellent bubble release and clarity, making it ideal for creative furniture, river tables, and large decorative pieces.
Practical Tips for Deep Pour Projects
When working with deep pour resin, preparation is essential. Ensure your mould is fully sealed and rigid to withstand the weight and volume of the pour. Mix carefully to maintain clarity and allow the product’s long working time to help bubbles escape naturally. Avoid exceeding the maximum recommended thickness in a single layer. For extreme projects or heavy pours (over 8 kg per layer), pouring in several layers with intervals can further protect your piece from overheating.
When This Matters
Selecting an appropriate deep-casting resin is critical for any project where you want a single, thick, clear layer—such as statement tables or artistic installations. Using standard formulas for these depths can result in failed casts or safety concerns.
