The special series of functional coating wollastonite fibers have good reinforcement properties, which can improve the toughness and durability of the coating, maintain the surface smoothness and good glossiness of the coating, and improve the anti washing and anti weathering performance of the coating, reduce the oil absorption of the coating and ink, and maintain alkalinity, with strong corrosion resistance. The coating not only has bright color, good uniformity and anti-aging performance, but also can enhance the mechanical strength, durability, adhesion and corrosion resistance of the coating.
