Fourth, the products are mainly used in the plastics action can improve the impact strength of products to enhance liquidity and improve the tensile strength, tensile strength and modulus of linear shrinkage. Having a good reinforcement in the paint, coatings can enhance the toughness and durability, and can keep the paint surface and smooth with good gloss. And improved resistance to washing and weathering performance, and can reduce oil absorption coatings and inks and maintain basic, with corrosion resistance. You can get high-quality brightly colored paint, and with good leveling and anti-aging properties. The coating can be better mechanical strength, increased durability, enhanced adhesion and corrosion resistance. There are good coverage, adhesion.
