Slow Curing, Low-Heat Formula Epoxy Resin: What to Know

Why Slow-Curing, Low-Heat Matters

Traditional epoxy resins produce heat as they cure, which can be problematic when pouring thick layers or working in large formats. Rapid curing can result in excess heat (an exothermic reaction), leading to yellowing, cracks or warping in your finished piece. Choosing a resin designed for slow curing and low heat release is crucial for castings over 2cm and particularly when working with volumes that might otherwise trap heat.

Product Choices for Slow, Cool Curing

• EpoxyTable 5-Five: Excellent for pours between 2 and 5cm, this resin offers a low exothermic reaction, providing you with a longer working window and reducing overheating risk. Its formula supports thick applications without sacrificing clarity or strength. Learn more about EpoxyTable 5-Five.
• Epoxytable 10-Ten: Designed for deep pour projects up to 10cm, this option is ideal for river tables and large artistic works, as it minimises heat build-up and bubbles. Pouring in one layer without significant overheating is possible within its specifications.
• Trasparente: For shallower pours up to 2cm, Trasparente delivers a crystal-clear finish with minimal heat generation—perfect for jewellery, tabletops, and delicate castings.

Practical Tips: Pouring and Environment

Pouring resin in a controlled environment helps further reduce overheating risks, especially with slow-curing formulas. Always follow the recommended maximum pour thickness: avoid exceeding 2cm for Trasparente, 5cm for EpoxyTable 5-Five, and 10cm for Epoxytable 10-Ten in one go. For particularly large or deep projects, consider pouring in multiple stages, allowing each layer to set before adding the next. Avoid using heat guns or high ambient temperatures, as these can accelerate curing and unwanted heat build-up.
