Multiphase Latex Leads the Way In Low-To Zero-VOC

摘要

Due to the higher polymer content of the paint film,there are greater performance demands for semi-gloss paints than for flat paints.These demands include gloss retention,block resistance and adhesion over previously painted glossy substrates.For exterior paints that are subjected to solar warming,block resistance performance is especially critical.As the regulations drive allowable VOC levels in paint formulations lower,these performance properties can become more difficult to achieve.In order to achieve low-VOC coatings,the paint formulator either uses latex with a low glass transition temperature(Tg),or one with high amounts of non-volatile film formers.
