Cellulose Ether for Texture CoatingsHEC for body, filler suspension, anti-sag behavior, and texture retention in water-based decorative coating formulations.

HEC (Hydroxyethyl Cellulose) is the most widely used cellulose ether in water-based texture coatings. It improves thickening, filler and aggregate suspension, rheology control, anti-sag behavior, texture retention, and storage stability across fine texture coatings, sand texture coatings, stone-effect coatings, relief coatings, and spray-applied texture systems.

HEC builds viscosity and coating body, suspends heavy fillers and aggregates to reduce settling, controls rheology during application, supports texture retention after placement, reduces sagging on vertical surfaces, and maintains stable in-can consistency during storage. It is a non-ionic thickener compatible with the anionic dispersants and polymer emulsions used in water-based texture coating systems.

Texture coatings contain higher filler loading, coarser particles, and heavier aggregates than standard wall paints. These heavier components require stronger viscosity and suspension support to prevent settling during storage, maintain texture pattern after application, and resist sagging on vertical surfaces.

Yes. Suitable HEC grades improve coating body and internal structural stability in the wet film, which supports better texture retention after application. However, final texture retention also depends on binder type, filler system, aggregate size, application method, and film thickness.

A common reference dosage range is 0.2%–1.3% by weight, depending on texture type, filler and aggregate loading, particle size, application method, and target viscosity. Stone-effect and relief coatings typically require 0.5%–1.3%, while fine texture and spray coatings may use 0.2%–0.8%. Final dosage must be confirmed through testing.

Yes. HEC improves coating body and structural recovery after application, which helps reduce sagging and running on vertical wall surfaces. The anti-sag effect depends on HEC grade selection, dosage level, filler loading, film thickness, and the complete formulation system.

Settling is typically caused by insufficient viscosity, weak suspension support, heavy aggregate density, poor dispersion during production, unsuitable HEC grade selection, incorrect dosage, or unbalanced formulation design. Increasing HEC dosage, selecting a higher viscosity grade, or improving the dispersion process can help reduce settling risk.

Start by defining your texture coating type, target viscosity, filler and aggregate system, particle size and density, application method, anti-sag requirement, and storage stability target. Then contact LANDERCOLL with these parameters — our technical team can recommend suitable HEC grades and provide samples for formulation evaluation.
