工业涂料用水性树脂的新进展

New Developments in Water borne Resins for Industrial Coatings

减少有机挥发物的含量已成为涂料研究的重要课题，因此，水性涂料将是涂料工业今后发展的主要方向之一。近年来工业涂料用水性树脂获得迅速发展。水性双组分聚氨酯金属涂料和溶性型涂料一样都具有相当好的柔韧性和附着力；醇酸乳液和新型丙烯酸分散体的产生为配制极低挥发份的木器涂料提供了可能性。

Reduction of volatile organic compounds has been the main objective of coatings research. Therefore, water borne coating will be one of the most important coatings in the future.Water borne Resins for Industrial Coatings have developed rapidly in recent years.Water borne two back polyurethane coatings for metal substrates have comparable flexibility and adhesion as solvent borne coatings.Alkyd emulsions and new acrylic dispersions offer the possibility to formulate coatings for wood with very low VOC contents.
