LANDERCOLL provides paint-grade HEC, HPMC, and selected cellulose ether products for interior wall paint, exterior wall paint, latex paint, emulsion paint, water-based coatings, texture coatings, architectural coatings, and selected industrial coatings.
Choosing the right cellulose ether depends on formulation type, target viscosity, thickening efficiency, emulsion compatibility, pigment and filler loading, pH conditions, storage stability requirements, application method, and final paint performance targets.
Cellulose ether builds viscosity in the water phase, supports pigment and filler suspension, controls rheology for roller, brush, and spray application, and helps maintain formulation uniformity throughout the product shelf life — typically at dosage levels between 0.2% and 1.0% by formulation weight.
Cellulose ether is used in water-based paint systems to improve viscosity, rheology, suspension stability, and application consistency. It helps paint remain uniform and processable throughout the entire product lifecycle — from the mixing tank through storage and transportation to the final application on the substrate. Without a suitable cellulose ether, paint may show poor viscosity stability, pigment settling, water separation, weak roller behavior, excessive splashing, sagging, poor leveling, or inconsistent batch performance.

Primary Thickener
Widely used in latex, emulsion, and water-based paint systems
Hydroxyethyl Cellulose (HEC) is the most commonly used cellulose ether in paint and coating formulations. It provides efficient thickening, clean water solubility, stable viscosity control, pigment and filler suspension support, and storage stability for interior wall paint, exterior wall paint, latex paint, emulsion paint, and general water-based coatings.
Selected Systems
Viscosity control, body, and rheology in specific coatings
Hydroxypropyl Methylcellulose (HPMC) may be used in selected paint and coating systems where water-based thickening, body, and rheology control are required — particularly in texture coatings and construction-related coating systems. Suitability in standard latex paint should be confirmed through compatibility testing.

Cellulose ether supports multiple formulation functions in water-based paint — from viscosity development in the mixing tank to application feel on the substrate.



Builds and maintains suitable viscosity for production, filling, storage, and application — supporting stable viscosity development during dissolution and consistent shelf-life performance.
Balances high-shear flow during roller, brush, spray, or airless spray application with low-shear structure during storage — reducing sagging, splashing, and poor leveling.
Helps titanium dioxide, mineral fillers, extenders, and functional pigments remain uniformly distributed — particularly in high-PVC formulations with significant filler loading.
Supports viscosity stability and formulation uniformity over months of storage — reducing thickener degradation, phase separation, and viscosity drift.
Contributes to application feel — reducing roller splash, improving brush drag behavior, supporting smooth leveling, and maintaining anti-sag performance on vertical surfaces.
LANDERCOLL can discuss viscosity targets, thickening efficiency, and grade options based on your paint type and emulsion system.

Cellulose ether performance in water-based paint is influenced by the complete formulation environment — not just the thickener grade alone.
The polymer emulsion — acrylic, styrene-acrylic, VAE, PVA, or other types — influences how cellulose ether behaves. Compatibility between the grade and emulsion system must be confirmed through testing.
Most cellulose ether grades perform within defined pH ranges. pH drift during storage — from additives, preservatives, or CO₂ absorption — can affect viscosity stability. Formulation pH should be characterized and controlled.
Dispersants and surfactants for pigment and filler dispersion can interact with cellulose ether, affecting viscosity development, thickening efficiency, and storage stability. The complete additive package should be evaluated together.
Higher PVC formulations with significant filler loading place greater demands on suspension stability and viscosity. Grade and dosage should be evaluated at the actual PVC level of the formulation.
Biocides and preservatives can interact with cellulose ether. Compatibility between the preservative system and the cellulose ether grade should be confirmed — particularly for long shelf-life products.
Cellulose ether must be properly dissolved and hydrated during manufacturing. Addition sequence, mixing speed, water temperature, and hydration time all affect final viscosity development and batch consistency.
Temperature fluctuations during storage and transportation can affect viscosity stability. Grade selection should consider the expected storage temperature range for the target market.
Before selecting a cellulose ether grade for production, paint manufacturers should evaluate it in their own formulation and under their own process conditions. Performance in a standard reference test may differ from performance in a specific production system with a particular emulsion, dispersant, and preservative combination.
Define the paint type and identify primary performance targets — viscosity level, thickening efficiency, storage stability, application behavior, or suspension performance.
Select a grade direction — HEC or selected HPMC — based on paint type and compatibility requirements.
Evaluate dissolution and hydration behavior in actual process water at the planned addition point in the manufacturing sequence.
Test viscosity development after mixing and confirm target viscosity at the planned dosage.
Check pigment and filler suspension stability after storage at ambient and elevated temperatures.
Evaluate application behavior — roller, brush, or spray — and assess splashing, leveling, and sag resistance.
Conduct storage stability testing over the target shelf life period and confirm viscosity retention.
Confirm compatibility with emulsion, dispersant, defoamer, and preservative system before production scale-up.
Paint manufacturers often ask when to use HEC and when to use HPMC. HEC is the primary cellulose ether for most water-based paint systems; selected HPMC grades support specific coating types where higher body and structure are required.
Hydroxyethyl Cellulose (HEC) is the most commonly used cellulose ether in water-based paint, latex paint, emulsion paint, interior wall paint, exterior wall paint, and general water-based coating formulations. It provides efficient thickening, clean water solubility, stable viscosity control, pigment and filler suspension support, and broad compatibility with emulsions, dispersants, and other paint additives. Final selection should be confirmed through formulation testing in the specific paint system.
Hydroxypropyl Methylcellulose (HPMC) may be used in selected water-based coating, texture coating, and construction coating systems where viscosity control, body, and rheology support are needed. HPMC can offer higher structure and anti-sag behavior in texture coatings. Its use in standard latex or emulsion paint should be confirmed through compatibility testing with the specific emulsion, dispersant, defoamer, and preservative system.

HEC is the most commonly used cellulose ether in water-based paint, latex paint, and emulsion paint. It provides efficient thickening, stable viscosity control, pigment suspension support, and broad compatibility with emulsions and other paint additives. Selected HPMC grades may also be used in texture coatings and construction coating systems.
HEC helps improve viscosity control, rheology behavior, pigment and filler suspension, storage stability, and application performance in water-based paint formulations. It dissolves cleanly in water and is compatible with most emulsion types, dispersants, and other paint additives commonly used in latex and emulsion paint systems.
HPMC can be used in selected water-based coating, texture coating, and construction coating systems where viscosity control, body, and rheology support are needed. Its use in standard latex or emulsion paint should be confirmed through compatibility testing with the specific emulsion, dispersant, and additive system.
A common reference dosage range is approximately 0.2%–1.0% by formulation weight, depending on paint type, target viscosity, thickening system design, solids content, and application requirements. Texture coatings typically require higher dosages. Final dosage must be confirmed through viscosity testing and formulation evaluation.
Viscosity changes during storage may be caused by thickener incompatibility with other additives, pH drift, poor initial dispersion, microbial degradation of the thickener, temperature fluctuations, or an unsuitable cellulose ether grade for the specific formulation. Suitable grade selection combined with proper pH control and preservative system can support better viscosity stability.
Cellulose ether can help improve viscosity and suspension stability, which supports pigment and filler distribution during storage. Final settling resistance depends on the complete formulation, pigment and filler particle size, dispersant system, and storage conditions. Cellulose ether is typically one component of a broader suspension management approach.
