Description

Hydroxyethyl Cellulose (HEC) is a non-ionic water soluble polymer obtained through a series of chemical processes from cotton linter (or wooden pulp).  Hydroxyethyl Cellulose (HEC) has long been used as rheology modifier, water retaining and stabilizer for latex paints. 

 

HEC can be used in all types of latex paints from low to high PVC. It suitable for all types of interior and exterior paints.

 

Introduction

Name: Hydroxyethyl cellulose

Abbreviation: HEC

Molecular formula: [C6H7O2(OH)3-x〖OCH(OH)CH3〗x]n

Characteristics:

Hydroxyethyl cellulose (HEC) is a non-ionic, water-soluble polymer derived from cellulose through a series of chemical and physical processes.

HEC is a white to light yellowish, oderless and tastless powder, readily soluble in hot or cold water to form a viscous gel solution. When pH in solution is within 2 to 12, the solution is quite stable. Since HEC group is nonionic one in water solution, it won’t be reacted with other anions or cations and insensitive to the salts. HEC also has good film-forming ability and surface activity.
