Powder Coatings Reduce Emissions

Many of our customers in the coatings industry rely on low-emission products. Thus, water-based systems are now the center of interest rather than conventional solventbased systems. We support this trend with our additives and pigments for water-based coatings.

Powder coatings are being used increasingly in industrial applications, particularly on metallic substrates. When they are processed, less waste is produced because the powder almost completely melts into the coating.

Thanks to new developments in recent years, we have been able to reduce the energy needed for application of powder coatings. As a consequence, the climate-relevant CO2 emissions of powder coatings can be reduced by 25 to 60 percent, depending on the thickness of the coating layer, compared to solvent-based systems, according to a new study in the Netherlands.

Our companies support this trend. In addition to special aluminum- and pearlescent-based effect pigments, ECKART also offers a so-called bonding service at its Hartenstein and Painesville sites. With the service, our customers’ basic powder coating products are processed with effect pigments.

BYK has a diversified additives portfolio that meets virtually all requirements when it comes to optimizing powder coating products and processes. It consists of wetting, dispersing, rheology, and surface additives that improve gloss and scratch resistance. In the U.S. and Europe, a number of these additives have been approved to come into contact with foods.
