To reduce the VOCs used in PU-based coatings, Yantai Wanhua Polyurethanes Co. Ltd. developed waterborne technologies including PUD, PUA and waterborne 2K.
After an inauspicious introduction more than a half-century ago, vinyl acetate-ethylene technology finally appears poised to go mainstream in the coatings market.
This article highlights a new cobalt-free catalyst that helps to achieve the necessary cure time as well as improve properties associated with water-based, high solids alkyds and alkyd-modified resins.
This study demonstrates that 2K waterborne polyurethane clearcoats can be a technology of choice in automotive clearcoat applications in order to combine high-demanding requirements and sustainability development concerns.
