LANDERCOLL HEC helps water-based coating manufacturers improve thickening efficiency, viscosity stability, pigment and filler suspension, application performance, and storage stability across interior, exterior, primer, and decorative coating formulations.
HEC (Hydroxyethyl Cellulose) is the primary cellulose ether used in water-based coatings. It functions as a water-phase thickener and rheology modifier that controls viscosity, supports pigment and filler suspension, improves brush and roller application, helps reduce sagging, and maintains stable in-can consistency throughout storage.
Water-Based Coatings · HEC
Viscosity control and pigment suspension for consistent brush and roller application.
Emulsion · Pigment · RheologyWater-based coatings are coating systems in which water serves as the primary liquid phase and dispersion medium. They incorporate polymer emulsions, pigments, fillers, additives, and functional modifiers to deliver decoration, surface protection, color, smoothness, or specialized performance across a wide range of substrates and environments.
Typical water-based coating products include interior wall paint, exterior wall paint, latex paint, emulsion paint, primers, texture coatings, façade coatings, waterproof coatings, protective coatings, and selected industrial coatings. The shift toward water-based systems continues to grow as formulators seek lower VOC content and improved environmental compliance.
A typical water-based coating formulation includes polymer emulsion, titanium dioxide, pigments, fillers, water, dispersants, wetting agents, defoamers, preservatives, pH modifiers, coalescing agents, rheology modifiers, and cellulose ether.
Cellulóz-éter — specifically HEC (hidroxietil-cellulóz) — is used as the primary water-phase thickener and rheology modifier. It controls viscosity, supports pigment and filler suspension, improves brush and roller application behavior, helps reduce sagging on vertical surfaces, and maintains stable in-can consistency during storage and distribution.

HEC is the primary LANDERCOLL cellulose ether product for water-based coating applications — delivering reliable thickening, viscosity stability, pigment suspension, and flow control in polymer emulsion systems.
HEC is widely used across interior wall coatings, exterior wall coatings, latex paints, emulsion paints, primers, decorative coatings, and selected industrial water-based coatings. It is a non-ionic, water-soluble cellulose ether with broad compatibility with anionic dispersants, surfactants, and polymer emulsions commonly used in water-based systems.
HEC hydrates readily in water and builds viscosity efficiently, providing consistent thickening performance across a range of coating types and pigment volume concentrations.
Water-based coating formulations vary by binder type, pigment and filler loading, target viscosity, application method, substrate, and market performance requirements.

Improve viscosity stability through grade selection.
Understanding the variables that influence HEC behavior in water-based coatings helps formulators make better grade selections, optimize dosage, and avoid common production and stability problems.
Different polymer emulsions — acrylic, VAE, styrene-acrylic, pure acrylic — affect viscosity response, compatibility, and film formation. HEC grade selection should be evaluated with the specific binder system.
TiO₂, calcium carbonate, kaolin, talc, silica, and colored pigments influence viscosity demand, suspension stability, and opacity. Higher filler loading increases thickening demand on HEC.
High pigment volume concentration systems typically require stronger suspension support and greater coating body control, often benefiting from medium to high viscosity HEC at upper dosage ranges.

Defoamers and preservatives may influence coating stability, viscosity, and application behavior. Compatibility with HEC should be evaluated during formulation testing.
HEC must be properly dispersed and fully hydrated to deliver target viscosity. Poor hydration may cause lumps, delayed viscosity development, or unstable viscosity.
Mixing speed, addition sequence, hydration time, temperature, and shear conditions can all affect final viscosity and coating stability.
Too little HEC may not provide sufficient thickening or suspension. Too much may reduce leveling, increase brush drag, or produce excessive application resistance.
Choosing the right HEC grade requires balancing viscosity target, rheology profile, pigment suspension needs, application method, leveling requirements, anti-sag support, and storage stability.
