Hydroxyethylcellulose is a valuable coating ingredient derived from cellulose, an abundant natural polymer found everywhere on Earth.
By treating cellulose with ethylene oxide, its structure is altered to accommodate the introduction of hydroxyethyl groups.
These groups, in turn, impart solubility and compatibility with a wide range of solvents, giving HEC its high functionality.
One of the essential tasks of hydroxyethylcellulose as a coating thickener is to control the rheology of the coating formulation.
By increasing the viscosity of the coating, hydroxyethylcellulose allows for precise control during application and guarantees the stability of the coating in the container.
As a result, a smooth, uniform surface effect can be achieved. In addition, HEC has the thickening effect required for coatings,
which can be fine-tuned by varying the concentration of the molecule in the coating formulation.
In addition to its thickening ability, hydroxyethylcellulose for architectural coatings enhances the overall performance of the paint by enhancing several indispensable properties.
Notably, water retention is very important, especially in waterborne coatings applied to porous substrates such as concrete, masonry and plaster.
By retaining water, HEC ensures that the paint film remains wet for a long time, thus promoting proper leveling and stable adhesion.
In addition, HEC brings excellent film-forming properties to coating formulations, making the coatings strong and durable enough to withstand rigorous environmental conditions.
Hydroxyethylcellulose promotes the formation of a continuous film, which enhances the barrier properties of the coating, protecting the substrate from moisture,
chemicals and other environmental factors.
