The formation of coating film of the weather-resistant pearlescent pigments was studied. The surface treatment mechanism of weather-resistant pearlescent pigment was studied by analysing the properties and structure of weather-resistant coating film and mica pearlescent pigments. The SEM and X-ray diffraction analysis were used.展开更多
