Pearlescent pigments are widely used in coatings, typically for additional color modifications such as automotive topcoats, automotive components, building materials, and household appliances, while achieving a certain degree of protection. The proportion of pearlescent pigments added to the coating depends on the desired effect, usually between 10-25%. When dispersed in the coating, pearlescent pigments can only be dispersed under relatively small shear forces, Mechanical energy can damage the crystalline state of pigments, causing loss of gloss. Only a short mixing time is allowed. It is recommended to apply equal mixing time and speed under the same conditions to manufacture the same batch of coatings.
