Using waterborne PU dispersion chemistry to coat glass containers boosts design freedom, durability

Dr. Raymond Stewart, senior R&D scientist, Bayer MaterialScience LLC, recently presented "Glass Coatings Technologies (Industrial Coatings Example),” at the Pittsburgh Society for Coatings Technology's September meeting. He discussed new coatings advances, with attention to polymer design and paint formulation for one component polyurethane coatings for the industrial coatings market, with an emphasis on glass containers. He also highlighted the benefits of using waterborne PUD chemistry, including improved design freedom, the ability to achieve a frost effect without acid etching, low VOCs, improved durability and reduced glass wall thickness. In addition, he described the superior performance of one component polyurethane coatings for various glass container market segments, including returnable bottles, decorative tableware, perfume bottles, decorative flatglass and non-returnable bottles. "Today's formulator is seeking new tools to develop coatings to meet customer needs," said Dr. Stewart. "Waterborne PUD chemistry is considered a benchmark for coatings performance and, as such, offers an excellent combination of properties for the demanding industrial coatings market."
