BINDER COMPOSITION AND PAINT FORMULATION MADE THEREOF

摘要

Provided is a binder composition comprising a first binder comprising by dry weight based on total dry weight of the first binder, from 5%to 98%of polymer particles, from 0.3%to 10%of a first polysaccharide, from 0.01%to 5%of a crosslinker, from 0.3%to 6%of a water-soluble metal cation, and from 0.05%to 3%of a cationic polyelectrolyte. The binder composition may further comprise a second binder comprising by dry weight based on total dry weight of the second binder, from 0.3%to 20%of the first polysaccharide, from 0.5%to 20%of a second polysaccharide. And in that case, the wet weight ratio of the first binder to the second binder is from 1:20 to 20:1. A paint formulation comprising the binder composition is also provided.
