【Abstract】 Titanium white is an excellent and expensive pigment, but usually effloresces under the ultraviolet light. The wollastonite pigment, which is ultra fined and modified in advance, was used in PVA coating. Tests of the properties of coatings with different formulas shows that the coverage of Ti modified wollastonite coating decreases slightly, but their other properties, such as anti ultraviolet ray and anti abrasion, increase greatly.更多还原
