Overview

Description

Hydroxyethylcellulose (HEC) is a non-particulate, water-soluble polymer that is a white, free-flowing granular powder. Hydroxyethylcellulose solution is a pseudoplastic fluid or shear thinning fluid, showing high transparency with different viscosities. In addition, low to medium molecular weight hydroxyethyl cellulose is completely soluble in glycerol and has good solubility in water-ethanol systems (up to 60% ethanol). Hydroxyethyl cellulose is used as a binder, adhesion aid, filling cement admixture, paint and optical brightener aid, coating polymer, filtration control additive, wet strength enhancer, protective colloid, rebound and slip reducing agents, rheology control modifiers, lubricity and operability enhancers, suspension stabilizers, shape retention enhancers and thickeners. Hydroxyethylcellulose can be used in multiple markets including adhesives and sealants, advanced ceramics, building and construction, ceramics, ceramics, commercial and institutional, oil and gas technology, metal casting and foundry, paints and coatings, personal care products, pharmaceuticals and paper and pulp.

Features

Fast hydration; Strong water-based adhesion; Insensitive to ions and pH; High salt tolerance; Surfactant Compatibility

Application
