Reducing reworking and powder consumption
The systematic measurement of powder coatings to keep their thickness to a minimum is a simple way of achieving major environmental benefits. Hand-held ultrasonic devices are the ideal solution for making non-contact coating measurements of this kind.
For around 20 years it has been possible to carry out non-contact measurements of uncured powder coatings using hand-held ultrasonic gauges to determine the coating thickness before the coating is cured in the oven. The result is that reworking and unnecessary powder consumption in many cases could become things of the past. Annual savings of 100,000 to 200,000 tonnes of powder could be achieved worldwide. This corresponds to emissions of 380,000 to 760,000 tonnes of CO2, which is the equivalent of a car travelling 2.2 to 4.4 billion kilometres (Euro 6)1. Despite the huge potential savings, many small and medium-sized powder coating companies are not yet using these measuring devices.
