Looking at the historical development of water-based resins, it has generally gone through the following three important stages: The first stage: external emulsification, which involves using external emulsifiers to achieve mechanical dispersion and thus make the resin water-based. Features: It has been made water-based, but the resin is very unstable and has poor performance. Second: The self-emulsification method, which achieves the water-based nature of the resin by introducing hydrophilic groups during resin synthesis. Features: The resin has good stability, but hydrophilic groups remain in the film after film formation; as a result, it has poor water resistance and its performance is average. Third: The self-crosslinking method, which achieves the water-based nature of the resin by introducing hydrophilic self-crosslinking functional groups during resin synthesis. Feature: The resin contains hydrophilic self-crosslinking functional groups, allowing it to disperse and dissolve easily in water, which facilitates application ； However, this hydrophilic self-crosslinking functional group crosslinks on its own as the resin dries and forms a film, undergoing self-reaction to create a dense protective network and a three-dimensional structure; as a result, it offers excellent water resistance, good adhesion, high gloss, and very comprehensive overall performance. Currently, the technically mature type among self-crosslinking water-based resins is self-crosslinking water-based acrylic resins
