Painting vs. Powder Coating

Paint booths are still popular despite the advent of powder booths. Powder coat beats the paint brush because of cheaper capital and running costs. The powder coat is tougher and resistant to abrasion. It also provides a relatively harder exterior than the paint film. Generally, It’s easier to provide the exact color and finish that you desire in a powder coat. The powder coat does not sag or run as the coat becomes thicker unlike in the case of the paint. Finally, wastage losses are almost zilch since the entire overspray can generally be recycled.

Thin paint films on the other hand are easier to apply, they are more stable under UV radiation and sometimes you get more color options than powder coats at a cheaper cost. The recycling of multi color overspray is not possible for powder coats. Finally, both paint and powder booths are popular in their own sphere of application.

Improving Product Value by Powder Coating

The relatively hard coating of a powder-coated product compared to a painted product and the production of the exact shade of the finish and color are some of the reasons of the popularity of the powder booth over the spray booth. Lower capital and running costs, wide range of thickness, extremely low volatile organic compounds and almost 100% utilization of the raw material are also the reasons why powder coating booths greatly improve product value.

Despite the fact that you can go in for a much thicker coat in the case of powder coating, there is no sagging or running which surely would have been true in the case of a normal paint coat.

A modern powder booth has a conveyor system that runs the products through the preparation section - involving blasting, washing, rinsing and drying. The prepared articles are powder-coated via an electrostatic mechanism and then baked in a conveyor oven.
