The organosilicon additives used in water-based coating systems are divided into two main categories: silane and silicone oil, as shown in Figure 1. Silane is mainly a small molecule compound, usually containing a silicon atom in its structure. It is mainly used as an adhesion promoter, diplomatic agent, dispersant, etc. in water-based coatings; the main components of silicone oil additives for water-based coating systems are It is some modified silicone oil. By adjusting the molecular weight of the auxiliary agent, the type and content of the modified group, and the type of the functional group of the end group, various auxiliary agents can be obtained.
