PCI recently traveled to the Powder Coating Summit in Lombard, Illinois, where low-temperature-cure powder coatings were a hot topic. PCI asked Dr. Robert Duan, ChemQuest president, and his colleague, Kevin Biller, to provide some background on the new trends, developments, and drivers pushing this topic to the forefront of the powder coatings industry.

The adhesion/corrosion balance of the previous study yielded significant new insights into resin design. Polymers with good wet adhesion and good corrosion resistance could be isolated, and those properties correlated back to their monomer compositions and particle morphologies.

The present study shows that the reactive diluent Tolonate X FLO 100, used in blend with conventional HDI-based polyisocyanates, can bring significant advantages to 2K polyaspartic systems.

Architectural low-VOC coatings can be formulated with dibenzoate glycol esters to have increased hardness, block resistance, gloss and scrub resistance.

This study utilized multiple hardness and tack testing procedures in order to fully understand the hardness profile of architectural paints.

In order to affect true change, we must develop products that touch on several of the change drivers, including regulatory issues, total cost of painting and performance
