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.

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.
Selulosa eter — specifically HEC (Hidroksietil Selulosa) — 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.

In water-based coating formulations, HEC supports thickening, rheology control, pigment and filler suspension, brush and roller application, leveling, anti-sag behavior, and storage stability — the properties formulators and end users evaluate most directly.
HEC builds viscosity in the water phase of coating formulations. Proper thickening improves in-can appearance, application control, coating body, suspension stability, and overall formulation consistency. At typical dosage levels of 0.2%–1.0%, HEC can build a wide range of target viscosities depending on grade selection and formulation conditions.
Water-based coatings require carefully balanced flow behavior. They must remain stable in the container, flow smoothly during brush or roller application, and recover sufficient body to resist sagging on vertical surfaces. HEC contributes to this rheological balance by providing water-phase structure that responds appropriately to shear forces during application.
Titanium dioxide, calcium carbonate, kaolin, talc, silica, and colored pigments must remain evenly distributed during storage. HEC increases water-phase viscosity and structure, reducing the rate of pigment and filler settling and supporting more consistent color, opacity, and texture.
HEC supports smoother application by improving coating consistency, transfer efficiency, spreading behavior, and application feel during brushing and rolling. A well-thickened coating picks up and releases from the brush or roller more consistently, reducing uneven application.
Good leveling helps reduce visible brush marks, roller marks, and uneven film appearance in the dried coating. HEC supports flow balance when properly selected and dosed within the complete formulation system.
For vertical wall coatings and thicker applications, HEC helps improve coating body and structural recovery after application, reducing the risk of sagging or running on vertical surfaces before the film dries.
HEC helps maintain viscosity and suspension stability during storage. This reduces pigment and filler settling, prevents hard sediment formation, and supports more consistent coating performance after extended shelf aging or temperature variation during distribution.
Many water-based coating stability and application problems are related to viscosity, rheology, and suspension — areas where HEC grade and dosage selection directly affect performance.

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.

HEC (Hydroxyethyl Cellulose) is the most widely used cellulose ether in water-based coatings. It improves thickening, viscosity control, pigment and filler suspension, rheology behavior, brush and roller application performance, and storage stability across interior wall coatings, exterior wall coatings, latex paints, emulsion paints, primers, and decorative coatings.
HEC builds viscosity in the water phase, stabilizes pigments and fillers against settling, improves brush and roller application consistency, supports leveling, helps reduce sagging on vertical surfaces, and maintains stable in-can viscosity during storage. It is a non-ionic thickener compatible with anionic dispersants and polymer emulsions.
Thickening helps coatings maintain product body, reduce pigment and filler settling during storage, improve application control during brushing and rolling, reduce sagging on vertical surfaces, and support uniform coating appearance in the dried film. Without adequate thickening, coatings become watery, unstable, and difficult to apply consistently.
A common reference dosage range is 0.1%–1.0% by weight, depending on coating type, target viscosity, pigment and filler loading, PVC level, and formulation design. Interior coatings typically use 0.2%–0.7%, while high-PVC decorative coatings may require up to 1.0%. Final dosage must be confirmed through viscosity testing and stability evaluation.
