Binder modifies the properties of coating color ( e g rheology, water retention) or coating
Binder are either modified natural products ( I e starch or protein based) or synthetic polymers. They form a film, whose properties combine with those of the pigment to give the desired coated paper properties.
Is a secondary binder used along with primary binder to improve the rheological properties of the coating color.
Used as a Binder in the formulation.
Develops higher water retention to the coating color.
Improves the surface strength of the coated paper.
Reduction in coating slip cost.
Improvement in the stiffness of the coated paper/paper board.
Potato starch is preferred due its clear,stable and high binding power characteristic.
Better ink adsorbency(receptivity).
Compatible with all kinds of Latex.
Better rheology,less mottling, low odour and taste,less yellowing and stable viscosity.
Improves the water resistance and wet rub resistance of the adhesive for offset grades and when printing by water based inks.
