Hydroxyethyl Cellulose (HEC)

HEC (Hydroxyethyl Cellulose)
Chinacel HEC (Hydroxy Ethyl Cellulose) is non-ionic cellulose ether, easily dispersed and dissolved in water. It provides thickening, colloid protection, construction property improvement, wetting and stability to final product to ensure high quality. It has high and even degree of substitution and excellent bio-stability, thus can be widely used in stone-like paints, latex paints, oil-drilling additives, detergent, toothpaste and etc

Product Details

Product Description

Hydroxyethyl cellulose is a gelling and thickening agent derived from cellulose. It is widely used in cosmetics, cleaning solutions, and other household products.[1] Hydroxyethyl cellulose and methyl cellulose are frequently used with hydrophobic drugs in capsule formulations, to improve the drugs' dissolution in the gastrointestinal fluids. This process is known as hydrophilization.[2]

Hydroxyethyl cellulose is also used extensively in the oil and gas industry as a drilling mud additive under the name HEC as well in industrial applications, paint and coatings, ceramics, adhesives, emulsion polymerization, inks, construction, welding rods, pencils and joint fillers.

Hydroxyethyl cellulose can be one of the main ingredients in water-based personal lubricants. It is also a key ingredient in the formation of large bubbles as it possesses the ability to dissolve in water but also provide structural strength to the soap bubble. Among other similar chemicals, it is often used as slime (and gunge, in the UK).

Hydroxyethyl cellulose (HEC) is a commonly used thickener in paint & coating formulations. HEC thickeners are used in paint & coating formulations to increase the viscosity of the paint and to improve its flow and leveling properties.[3]

HEC Application 

Chinacel HEC (Hydroxy Ethyl Cellulose) is non-ionic cellulose ether, easily dispersed and dissolved in water. It provides thickening, colloid protection, construction property improvement, wetting and stability to final product to ensure high quality. It has high and even degree of substitution and excellent bio-stability, thus can be widely used in stone-like paints, latex paints, oil-drilling additives, detergent, toothpaste and etc.

Dissolve Hydroxyethy Cellulose in water
Retarded Hydroxyethy Cellulose can be directly added into paint formulation, will form homogeneous, glazed solution. Period from powder wetted till dissolution completed call hydration time. During this process, solution build up thickening ability.

Temperature and PH has effect on hydration time. Increase PH to 8.0-10.0, will shorten the time 40-60%; temperature increase will shorten this time as well.

Normally, we suggest to add Hydroxyethy Cellulose at room temperature and neutural situation, hydration time is around 25 minutes.

Application Guide for Paint Industry
High Thickening Effects

ChinaCel Hydroxyethy Cellulose provides the latex paints especially high PVA paints with excellent coating performance. When the paint is thick paste, no flocculation will occur.
ChinaCel Hydroxyethy Cellulose has higher thickening effects, so can reduce the dosage, improve the cost-effectiveness of formulation, and enhance the washing resistance of paints.
Excellent Rheological Properties
The aqueous solution of SidleyCel Hydroxyethy Cellulose 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.
Dispersion and Solubility
SidleyCel Hydroxyethy Cellulose 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.
The SidleyCel Hydroxyethy Cellulose after a proper surface treatment can well regulate the dissolution rate and viscosity increase rate of the product.
Storage Stability
ChinaCel Hydroxyethy Cellulose has good mildew-resistant performance, provides enough storage time for paints, and effectively prevent settlement of pigments and fillers.
