EPOXY’S BEST TEMPERATURE.
What temperature should epoxy be poured? To obtain the best results, we recommend to mix, pour and let the epoxy cure at 72F. Once the epoxy resin and hardener are mixed together, the chemical reaction will start. If the exothermic reaction is affected by cold ambient temperature after the epoxy is mixed, it may take longer for the epoxy to cure. On the other side, warmer temperature will speed up the process. This is why you want to avoid temperature changes. Keeping a steady room temperature of 72F (22C) throughout the process will assure better results.
Ambient temperature has a direct impact on the working or handling properties of epoxy. The viscosity of epoxy resin will be drastically affected by colder temperature. If the room temperature is below the recommended temperature, the viscosity will increase. If the epoxy is getting thicker, it might be harder to mix and pour and will reduce its ability to flow without creating bubbles.
What temperature should epoxy be poured? WORKING AREA TEMPERATURE:
What temperature should epoxy be poured? It is imperative to work at a temperature of 22 degrees C (72 degrees F) and keep this temperature for the entire job. Avoid lowering the temperature overnight. Also, the work area should be located away from exterior doors that open frequently during the fall and winter periods. Any exposure to cold will slow down the exothermic effect and at the same time, the polymerization time.
STORE THE PRODUCTS ON A SHELF AT A TEMPERATURE OF 22C/72F:
The colder the product, the more the exothermic reaction will be reduced and the polymerization time will slow down. In addition, the viscosity of parts A and B will increase and decrease the efficiency of the boiling. The higher the starting temperatures of parts A and B, the more the reactivity of the system will be accentuated, leading to yellowing, shrinkage and the possibility of cracks.
