How cold can you use West System epoxy?
We know that most epoxies perform well or, at least reach a higher percentage of their potential physical properties, at temperatures of 60°F and above. Some resin/hardener combinations are formulated to cure in temperatures as low as 35°F.
Is West System epoxy heat-resistant?
105 Resin is a clear, low-viscosity liquid epoxy resin. Formulated for use with one of four WEST SYSTEM hardeners, it can be cured in a wide temperature range to form a high-strength solid with excellent moisture resistance. Resin viscosity is approxi- mately 1000 centipoise (cP) at 72°F (22°C).
What temperature is too high for epoxy?
Usually, Epoxy can withstand up to 150 degrees / 300° Fahrenheit for a short period of time. Heat-resistant epoxy can withstand the extreme heat of up to 600° Fahrenheit depending on the manufacturer and product.
How cold is too cold for epoxy?
In cold weather (below 50 degrees) you will notice the curing of ART’s Epoxy System begin to slow. The colder it gets the slower it takes to fully harden. A thin repair completed at 35 degrees may take as long as a week to fully cure.
What temperature does it need to be for epoxy to cure?
One of the most important factors to ensure your epoxy resin cures properly is temperature. The ideal temperature for both your ArtResin and your workspace is slightly warmer than room temperature: 75-85F or 24-30C.
How strong is West System epoxy?
| Compare Epoxy Physical Properties | ||
|---|---|---|

How long does West system take to cure?
6-8 hours
#205 Fast Hardener, mixed at a 5:1 ratio with #105 Resin, results in a pot life of 9-12 minutes at 72°F, with solid cure in 6-8 hours.
What is the best temperature to cure epoxy resin?
75-85F
One of the most important factors to ensure your epoxy resin cures properly is temperature. The ideal temperature for both your ArtResin and your workspace is slightly warmer than room temperature: 75-85F or 24-30C.
Does temperature affect epoxy curing?
The warmer the temperature of curing epoxy, the faster it cures (Figure 1). Heat speeds up epoxy chemsitry or the chemical reaction of epoxy components. Generally, epoxy cures faster when the air temperature is warmer. Exothermic heat is produced by the chemical reaction that cures epoxy.
How long does it take for West System epoxy to cure?
6 to 8 Hours

What happens if resin is too cold?
Resin prefers warm temperatures (not hot) and doesn’t like excess moisture. Resin that’s too cold is like molasses. Since part of the curing process is a chemical reaction causing heat, resin that’s too cold can have problems curing properly. Sometimes resin that cures soft and bendy cured at too cold a temperature.
