In the coating field, after adding it, a dense protective layer can be formed on the surface of the coating, significantly enhancing the scratch resistance of the coating, effectively resisting daily friction and scratches; in the ink industry, the micronized linear low molecular weight polymer can improve the film-forming performance of the ink, not only greatly improving the wear resistance of the printed pattern, making the color last bright, but also optimizing the coating touch, bringing a delicate, smooth unique feel. With these excellent properties, this series of products has become a key material for improving product quality and enhancing market competitiveness in industries such as coatings and inks, and is highly favored by the industry.
