Wanzhao Chemical has developed a unique process to prepare high-quality waterborne coating reinforcing agent, which can greatly increase the tensile and tear resistance of nano-film coatings by 20-50%, in addition, it can also improve the yellowing resistance and mildew resistance of waterborne coatings. This material is widely used in waterborne systems such as architectural waterborne coatings, outer packaging coatings and film coatings that need to improve the tensile strength.
