Coating Binder Migration and its Affected Parameters: Influence of Coating Color on Binder Migration

Article Preview

Abstract:

The Paper studied the effects of coating color on binder migration and affected factors. The z-direction distribution of the coating binder which was tagged with Br in coating layer and its concentration in coating surface were examined quantitatively by using SEM-EDXA and ESCA analysis. In coating colors the coating solid content, the binder dosage and type affects the binder migration. The mechanism of coating color on binder migration was also studied. The results indicated that the degree of binder migration was increased with reduced the coating solid content or added more dosage of coating binder. In low dying temperature the SB-latex was prone to migrated to coating layer surface than starch, the opposite is true in high dying temperature.
