If you’re tackling big resin projects—such as tabletops, river tables or large decorative items—you’ll want a product that enables thick castings up to 5cm, all while minimising heat build-up. Choosing a deep pour epoxy with a low exothermic reaction ensures a safer and more controlled curing process for your creative work.
Why Low Exothermic Reaction Matters for Deep Pours
The exothermic reaction is the heat generated when resin cures. For deep pour projects, using a resin with a low exothermic profile is vital. Rapid heat build-up can cause cracking, yellowing, or distortions in your clear castings. By selecting a resin designed specifically for thicker pours, you reduce the risk of thermal issues and ensure a clear, bubble-free finish from edge to centre.
Working with Epoxy for 5cm Castings
Deep pour epoxies, such as EpoxyTable 5-Five, are formulated to allow castings up to 5cm in a single pour. They benefit from low viscosity for improved bubble release and slow curing, giving you flexibility during the working phase. Apply in a dust-free, temperature-controlled space, and pour in one steady movement to avoid lines or cloudiness. For pours over 5cm in depth or extremely large areas, layering the resin may deliver the best result.
When Does This Type of Resin Matter Most?
- Creating river tables and statement furniture pieces
- Large art projects needing crystal-clear depth
- Situations where reducing heat and avoiding rapid curing is essential to prevent flaws
