Paint Booth and Reflow ovens

Powder coatings have a four-stage fundamental curing process (cure schedule):

  • Melt the powder.
  • Flow out the powder.
  • Crosslink and cure the powder.
  • Achieve adequate crosslinking.

Temperature, time at temperature, and, in some situations, the pace of temperature change all have a significant impact on these stages. These phases govern the majority of powder coating final qualities and are hence temperature sensitive. The disadvantage of the conventional approach of temperature monitoring of paint ovens and other furnaces is that the product temperature is approximated from the oven temperature. Thus, the impacts of the variables such as track speed, substrate thickness, and thermal uniformity of the oven on component heating rate are ignored.

These types of issues can be resolved by measuring the temperature profiling of the product via a suitable thermal profiling system developed by Tempsens instruments Pvt. Ltd.
