difficult development of container water paint

Container water paint with anticorrosion properties to achieve the same anti-corrosion coatings, technically difficult, because there are certain solvent-based coating with waterborne coatings in film forming mechanism of difference in the film properties differences. At present the main problem is: container raw speed unceasing enhancement, the fastest production tempo has reached every teu 3.5 min a, doubtless for container coatings of waterborne change an increased level of difficulty. Container water paint development needs to solve the anticorrosion properties, production line construction performance, coating higher cost three technical problems, and funds, management and so on a series of problems. At present, can completely meet the requirement of three coating production line of the whole container water paint manufacturers also are few in number. In a text editor last year was found in the technical literature difficult in technology implementation obtain a breakthrough, the paper say that by using with waterborne epoxy resin as anti-corrosion primer and water-based acrylic modified alkyd resin as topcoat supporting system, anti-corrosion performance reach container outer system technical requirements, Inner system with no weatherability requirements can adopt waterborne epoxy system. This product has successfully developed for container industry use water-based coatings have opened up a new roads, with a great market potential.
