ABSTRACT:
Tannin block properties in surface coating compositions are increased by admixing a sol or gel containing one or more salts with a polymer and a surface coating paste stock. A novel surface coating composition containing a polymer and salt homogeneously distributed in the composition is prepared from the sol or gel and has increased tannin block properties compared to a composition without the admixed sol or gel.
