Deep Pour Epoxy Resin: Achieving Up to 5cm Thickness with Low Heat

Why Low Heat Generation Is Vital for Deep Pours

Epoxy resins generate heat as they cure—a process known as exothermic reaction. When casting thick sections (such as up to 5cm deep), selecting a resin formulated for low heat generation is crucial. Excessive heat can lead to yellowing, cracking, or even structural issues in the finished piece. Deep pour resins use a special blend that cures more gradually, keeping the temperature in check and allowing thick, bubble-free applications for large furniture items.

Choosing and Using Deep Pour Resin

When your project requires a single pour thickness between 2 and 5cm, look for products labelled specifically for ‘deep pour’ use, such as the EpoxyTable 5-Five. This resin allows up to 5cm casting and is well-suited to river tables, embedded materials, or thick decorative coatings.

• Preparation: Ensure moulds or formwork are properly sealed to prevent leaks.
• Mixing: Follow precise mixing ratios and combine components carefully to avoid streaks and bubbles.
• Pouring: Pour the resin steadily and monitor the process for any signs of excessive heat. For very large or wide castings, consider layering with intervals as recommended in the product instructions.

When Deep Pour Matters Most

Choosing a formula for up to 5cm casting is especially important for river tables, thick countertops, or furniture pieces where a solid, clear mass is needed with minimal visible seams. Using a standard coating resin instead could result in uneven curing or surface imperfections.
