Thickeners coating color

Anionic starches are obtained by reaction with phosphoric acid and alkali metal phosphates or by derivatization with carboxymethyl groups.30,31 This modification is primarily used to introduce amphoteric properties into cationic com starch for application on the wet end of the paper machine. Anionic starches with carboxymethyl substitution are used as thickeners in coating colors or as binders in coatings for specialty paper grades. Oxidized starches are inherently anionic but without thickening action. Potato starch already carries sufficient natural anionic charge to provide amphoteric properties after cationization.32...

The interaction between the polymer and water has a pronounced effect on the viscosity of the aqueous phase as weU as on the water retention of the coating color. Like aU hydrocoUoids, synthetic thickeners bind a large number of water molecules along their polymer chains, with the result that their diameter and volume increase and they occupy a greater space in the aqueous phase (Fig. 3.14). Apart from...

Protein produced from solvent-extracted meal has been used as a thickening agent in soups, baby foods, high-protein foods, instimtional meals, and meat products. Groundnut proteins have also been used to manufacture a soft, wool-like, cream-colored fiber, adhesive products such as plywood glue and wettable glue, and for paper coating.
