Leverkusen, Germany-A new coatings ingredient from Bayer MaterialScience is helping coatings manufacturers develop formulations for high-performance polyurethane coatings which meet the latest regulations on solvent content and emissions, said the group in a 3 April statement. Emphasis has shifted towards environmentally compatible coatings with lower volatile organic compounds (VOC) content recently, said BMS, adding that its new low-VOC offering, Bayhydrol XP 2592, is a cosolvent-free, waterborne polyester-polyurethane dispersion. The material helps users meet the requirements of the VOC Directive without costly, complex waste air purification, BMS said. Typical uses of these coatings are for metal industrial goods such as shock absorbers, axles and agricultural machinery."What distinguishes Bayhydrol XP 2592 is its extreme versatility," said Dr Ulrich Freudenberg, an expert on polyurethane industrial coatings at Bayer MaterialScience, in the company press release. BMS's new binder can be used in primers and single-layer coatings offering very good corrosion protection. It can also be used in high-gloss topcoats for good chemical and weathering resistance, or even effect coatings. The material is also versatile in application, which can be by spray, dip, flow and roller.Although the binder was originally developed for air drying and forced drying-with atmospheric oxygen driving crosslinking-BMS points out that its hydroxyl functionality also allows it to be used in baking coatings, with amino resin crosslinking, and in two-component coatings, with polyisocyanate crosslinking.
