Low Exothermic Epoxy Resin for Deep Casting up to 10cm

Low Exothermic Reaction Epoxy: Deep Casting up to 10cm

For large resin river tables, thick art castings, or unique projects, using an epoxy resin with a low exothermic reaction makes it possible to pour up to 10cm deep in one go. This approach helps minimise overheating and ensures clear, consistent results.

What is Low Exothermic Resin?

Low exothermic epoxy resin is specially formulated to generate less heat during curing. This important property allows for thicker single pours—up to 10cm—without risking overheating, cracking or discolouration. These resins typically feature a slower cure time and very low viscosity for easier degassing, supporting large projects like river tables and deep castings.

Choosing and Using Deep Pour Resin

When planning a deep pour of up to 10cm, select a resin explicitly engineered for this depth. For example, “Epoxytable 10-Ten” offers super-low viscosity, strong UV filters, and a low exothermic profile. Always follow the manufacturer’s instructions for mixing, pouring temperature, and curing intervals, particularly on very large or heavy pieces. Pouring in a stable, dust-free environment also helps assure a glass-clear finish.

When Deep Pour Matters Most

Low exothermic deep pour resins are crucial when creating river tables, thick art blocks or castings where depth adds strength and visual impact. Attempting such pours with standard epoxy can lead to unsafe heat build-up and disappointing results, so choosing a product designed for the challenge is essential.
