Castings Up to 5cm with Low Exothermic Reaction

Why Exothermic Reaction Matters

When resins cure, they create heat—a process known as an exothermic reaction. In thicker pours, too much heat can lead to bubbles, yellowing, or even cracks. Using a resin formulated for low exothermic reaction is crucial as it significantly reduces the risk of heat-related flaws, keeping your casting crystal clear and structurally sound.

Choosing the Right Resin for 5cm Pours

For castings up to 5cm, specialist deep pour epoxy resins such as “EpoxyTable 5-Five” are specifically designed to minimise heat during the curing process. These resins allow you to achieve a thick, clear pour without having to split your project into thin layers, making them ideal for tabletops, furniture, or large decorative pieces. For even deeper pours, consider “Epoxytable 10-Ten”. For smaller projects, “Trasparente” is a great option for crystal-clear results up to 2cm thickness.

Practical Tips for Successful Deep Casting

• Work in a cool, well-ventilated space to naturally limit temperature rise during curing.
• Always follow the manufacturer’s mixing ratio and instructions for best results.
• If your project exceeds 5cm in any part, consider pouring in two stages to ensure even curing.
• Avoid direct sunlight as it can accelerate curing and increase heat.
