Product Description

HYDROXYETHYL CELLULOSE  HEC
Brief Introduction
HEC is a nonionic cellulose derivative that dissolves readily in water, either cold or hot. It is made from natural macromolecular material cellulose through a series of chemical processing. It is used to produce solutions having a wide range of viscosity. Such solutions are pseudoplastic, that is, they vary in viscosity depending upon the amount of stress applied.

HEC-E
Biostable grade HEC-E give powerful, stable thickening in both interior and exterior paints. A creamy in-can stability, excellent water resistance and a good rheology profile. At the same time, it serves as a protective colloid in emulsion polymerization. Also, it's produced with a special process that gives superior biostability to product and this process doesn't make any difference in the chemical and physical property.

Application Guide for Paint Industry

1. High Thickening Effects

Biostable grade HEC-E provides the latex paints especially high PVA paints with excellent coating performance. When the paint is thick paste, no flocculation will occur.
Biostable grade HEC-E has higher thickening effects, so can reduce the dosage, improve the cost-effectiveness of formulation, and enhance the washing resistance of paints.

1. Excellent Rheological Properties

The aqueous solution of HEC is a non-Newtonian system, and the properties of the solution are called thixotropy.
In the stationary state, after the product is completely dissolved, the coating system can maintain the best thickening condition and can-opening state.
In the dumping state, the system can keep a moderate viscosity, making products with excellent fluidity, and not spatter.
During brushing and roller coating, the product is easy to spread on the substrate, so convenient for construction, and meanwhile, has good spatter resistance.
Finally, after the coating of paint is completed, the viscosity of the system will immediately get restored, and the paint will immediately produce sagging property.

1. Dispersion and Solubility

HEC is all treated by the delayed dissolution, and in the case of adding dry powder, can effectively prevent caking and make sure hydration starts after the adequate dispersion of HEC powder. After a proper surface treatment, it can well regulate the dissolution rate and viscosity increase rate of the product.
