Why Does Epoxy Resin Get Hot? Understanding Exothermic Reaction

7 Important Points

1. Epoxy curing creates heat naturally.
2. This is called an exothermic reaction.
3. Larger mixed quantities can generate more heat.
4. Thick pours can retain heat.
5. Higher room temperatures can increase curing activity.
6. Excessive heat can damage a project.
7. Always follow the manufacturer's recommended pour depth.
