the influence of cmc on paper coating properties

The Influence of CMC on Paper Coating Properties

Carboxymethyl cellulose (CMC) is the most widely used co-binder and rheology modifier in paper coating. This work presents an investigation on the effects of CMC on coating structure development by measuring viscosity of the coating colors and by characterizing properties of the dried coatings. The results showed that CMC addition increased coating color viscosity and impeded latex migration
