Research Progress in Zero VOC Acrylic Coatings

On the basis of analyzing the major source of VOC in water-based coatings,ways used to eliminate VOC were introduced from preparing emulsions and selecting additives. The techniques, such as polymerizing core-shell emulsion,adding functional monomers and blending soft-hard latex coatings, which have been used to solve the inconsistent relations between the high glass transition temperature and the low minimum film forming temperature of emulsions,were discussed in detail. The preparation of acrylic paint and its modification was focused on. Zero-VOC coatings can adapt to future environmental requirements.
