Coating Grade CMC

YUCMC® Coating Grade CMC as one kind of protective colloid, It will enhance the stability of emulsion polymerization system to evenly scatter the additive of pigment, filler, etc. into painting so as to impart it with good pigment adhesion effect.

INTRODUCTION

CMC is macromolecule compound with multichain, and the linear chain will open, spread, interact and form the network collide after the water swelling. Meanwhile, the macromolecule chain with oxhydryl has hydration with water and twine with each other, and then increase the water phase viscosity. It has the excellent compatibility in water or in organic solvent, as well as the pigment. It used as thickener, dispersant and stabilizer in coating industry.

FUNCTIONS

1. The macromolecular chain with the hydroxyl group of CMC is wound by hydration with water, which increases the viscosity of the product and has good solubility in water or organic solvents;

2. Excellent thickening effect, can prevent the coating separation due to temperature change, can also ensure that the coating does not precipitate in storage;

3. Good compatibility of pigments, greatly improving the rheological properties and viscosity of coatings;

4. Make full use of the good hydrophilicity of CMC, which can make good durability after coating.

5. It is often used as thickening agent, dispersant and stabilizer in coating industry.
