Temperatures Impact Epoxy's Cure Time: How Do I Adapt? | WEST SYSTEM® Epoxy Tips

Описание: Epoxy is temperature-sensitive—it needs to be warm to cure properly, but too much heat can lead to uncontrolled exotherm causing yellowing, smoking, or cracking. Technical Advisor Rachael explains how to manage temperature across three key areas: the epoxy itself, the surface (substrate), and the surrounding environment. Additionally, she discusses:

• How epoxy behaves when it gets too hot—or too cold
• Why selecting the right hardener matters
• Tips to minimize the impact of cold temperatures on epoxy
• Tips for extending working time in hot weather
• What to do if your epoxy crystallizes
• How to build a cooler box
• When and how to use products like G/flex® or Six10® in cold conditions

🔥 Pro Tip: As temperatures change, it's good to note that for every 18°F/10°C change in temperature, the cure speed of the epoxy will double or halve. For example, when using 105 Epoxy Resin with the 206 Slow Hardener (at 72°F/22°C in a thin film), the working time is about two hours. At 90°F/32°C, working time is about one hour.

As the temperatures change in your work environment, it's good to reevaluate your hardener selection and your application processes to get the best results.
