Problems solved by technology

[0002] All coatings that use water as a solvent or as a dispersion medium can be called water-based coatings. Most of the water-based coatings used on the market use resin as a base material and are synthesized from various pigments, fillers and additives. The main disadvantages of current water-based coatings are: The mechanical properties are poor, the adhesion cannot meet the requirements, and the scrub resistance and shelf life cannot meet the requirements, resulting in cracking and falling off of the wall surface, which not only affects the appearance of the building, but also cracks the wall surface, resulting in water leakage on the wall surface
