Introduction

COSPAR® CMC can be used for three processes during the paper making production: pulping, size press and coating.

COSPAR® used in the pulping process act as wet end additive that can help increase the strength of paper well.

COSPAR® used in size press and coating process act as retention agent and dispersing agent that can regulate the rheology during the coating process.

Functional Property

COSPAR® CMC can help control and adjust the rheology of coating and the dispersion of pigment to obtain coating with pseudoplasticity, enhance the water retention of the coating and have good film-forming property. Adding to the slurry: it can improve the refining efficiency, shorten the beating time, and improve the retention rate of various additives, fillers and fine fibers; applying on surface: it has good rheological and film-forming properties, so it can increase the brightness, glossiness, stiffness and smoothness of the paper and improve the surface strength and wear resistance of the paper. Compared with traditional sizing agent (PVA) and wet-end additive (PAM), it has the advantages of small dosage, suitable for all kinds of high, medium and low coating speed, stable paper quality, simple sewage treatment, environmental protection, etc.

Paper-making Grade CMC with Special Specification: Granular CMC, Ultra-low Viscosity CMC.
