How to Manage Exothermic Reactions in EpoxyTable Series Resin

Q: Best Practices for Safe and Controlled Pours

Follow recommended layer thickness: For EpoxyTable 5-Five, pour between 2 and 5 cm per layer; for deeper pours, use Epoxytable 10-Ten, but do not exceed advised limits. For surfaces over 100 cm or when using large amounts, pouring in several stages with waiting periods allows heat to dissipate. Maintain optimal working temperature: Room temperature between 18–25°C helps slow down the exothermic reaction and extends working time, reducing the risk of premature gelling or bubbles. Mix with care: Always respect the precise mixing ratios (e.g., 100:55 by weight for EpoxyTable 5-Five) to ensure a consistent cure and minimise risks. Thorough mixing also helps produce bubble-free, strong results. You can find resins with a controlled exothermic reaction and long working time, such as EpoxyTable 5-Five , ideal for medium-depth projects and large table surfaces.

Controlled Exothermic Reactions with EpoxyTable Series

When working with the EpoxyTable series of resins for deep pours and large projects, carefully managing the exothermic reaction is key to achieving a flawless result. Overheating or unexpected gelling can be avoided with the right approach.

Understanding Exothermic Reactions in Epoxy Resin

As epoxy resin cures, a chemical reaction releases heat—known as the exothermic reaction. The greater the mass or thickness of the pour, the more heat is generated. In the EpoxyTable series, formulas are optimised for lower exothermic heat, supporting casting depths up to 5 cm with EpoxyTable 5-Five and up to 10 cm with Epoxytable 10-Ten. However, exceeding recommended thickness or volume in a single pour increases the risk of overheating, rapid curing, or surface defects.

When Careful Exotherm Control Matters Most

Proper exothermic management is especially crucial for large resin tables, river tables, and furniture where thick layers are poured. In these cases, ignoring staged pouring or environmental factors could cause cloudiness, warping, or even resin scorching. Always plan your process and equipment to handle the amount of resin safely and efficiently.
