The Role of Hydroxyethyl Cellulose Hec in Latex Paint

Hydroxyethyl Cellulose HEC Introduction:

Hydroxyethyl cellulose (HEC) is a non-ionic cellulose ether made from cellulose, a polymer material, through a series of chemical processes. It is a white powder or granule, which can be dissolved in cold water to form a transparent viscous solution, and the dissolution is not affected by the pH value. It has thickening, binding, dispersing, emulsifying, film-forming, suspending, adsorbing, surface active, moisture-retaining and salt-resistant properties.

The role of hydroxyethyl cellulose HEC

High Thickening Effect

Hydroxyethyl cellulose provides excellent coating properties for latex coatings, especially high PVA coatings. No flocculation occurs when the paint is a thick build.

Hydroxyethylcellulose has a higher thickening effect. It can reduce the dosage, improve the economy of the formula, and improve the scrub resistance of the coating.

Excellent Rheological Properties

The aqueous solution of hydroxyethyl cellulose is a non-Newtonian system, and the property of its solution is called thixotropy.

At rest, the coating system remains thickened and open-can after complete dissolution of the product.

In the state of pouring, the system maintains a medium viscosity, so that the product has excellent fluidity and will not splash.

The product spreads easily over the substrate when applied by brush and roller. It is convenient for construction. At the same time, it has good splash resistance.

When the coating is finished, the viscosity of the system recovers immediately, and the coating immediately sags.

Dispersibility and Solubility

Hydroxyethyl cellulose is treated with delayed dissolution, which can effectively prevent agglomeration in the case of dry powder addition. After ensuring that the HEC powder is well dispersed, start hydration.

Hydroxyethyl cellulose with proper surface treatment can well adjust the dissolution rate and viscosity increase rate of the product.

Storage Stability

Hydroxyethyl cellulose has good anti-mildew properties and provides sufficient paint storage time. Effective prevention of pigment and filler settling.
