HEC for Water-based Latex Paint

1.Brief Introduction

HEC is produced from cellulose, which reacts with sodium hydroxide to form basic cellulose colloid. And then the ethylene oxide and other chemicals are added into the reaction to get etherification. By controlling the production parameters, the Hydroxyethyl cellulose is produced.

HEC is a white or light yellow powder, non-toxic, tasteless, can be quickly dissolved into hot or cool water, insoluble in general organic solvent, with excellent character of thickening, dispersing, emulsifying, adhesion, stabilizing, water retention and film forming. Also can be used as a protective colloid in some products. It can be widely used in oil drilling, coatings, food, textile, building and macromolecule polymerization, etc.

3.HEC for Water-based Latex Paint

HEC is the most commonly used thickener in latex coatings. In addition to thickening latex paint. At the same time, it can emulsify, disperse, stabilize and retain water. It is characterized by significant thickening effect, good color development, film-forming properties and storage stability.
HEC is a nonionic cellulose derivative that can be used in conjunction with other materials in the component (such as pigments, additives, fillers, and salts) within a wide pH range, and has good compatibility.
Coatings thickened with HEC have good rheology at various shear rates. And has pseudoplasticity. Construction methods such as brushing, spraying, and roller coating can be used. It has good workability, is not easy to drip, sag and splash, and has good leveling properties.
