About LANDU Hydroxyethyl Cellulose (HEC)
Hydroxyethyl Cellulose (HEC) is a non-ionic, water-soluble polymer derived from cellulose, a natural component of plant cell walls. Think of it as a microscopic network builder. It’s created by modifying cellulose with ethylene oxide, resulting in hydroxyethyl ether groups attached to the cellulose backbone. This modification gives HEC its unique properties, especially its ability to thicken water-based solutions like emulsion paint. But what is the magic of HEC? Imagine building a tiny jungle gym of molecules within the paint. These act like the supporting structure of playground equipment, which is responsible to hold the weight from all directions.
HEC plays varying roles based on the quality and intended use of the paint:
In these paints, HEC primarily functions as a cost-effective thickener and stabilizer, preventing pigment settling and providing basic application properties.
HEC provides improved viscosity control, leading to better hiding power, leveling, and sag resistance compared to economy paints.
Here, HEC works in synergy with other additives to create a high-performance paint with exceptional application properties, durability, and color retention. It ensures smooth flow, excellent coverage, and long-lasting protection.
Increase shelf life and maintain quality over time.
Prevent premature drying for a smoother finish.

| Condition | Paint Type | LANDERCOLL Recommendation |
|---|---|---|
| Interior, Economy | Latex Paint | LANDERCOLL HE30M |
| Interior, Standard | Acrylic Paint | LANDERCOLL HE60M |
| Exterior, Premium | Elastomeric Coating | LANDERCOLL HE100M |
| High Humidity | Interior/Exterior | LANDERCOLL MEB30M or MEB60M |
| Delayed Thickening Desired | Tint Bases | LANDERCOLL MHE500 |
| Problem | Solution |
|---|---|
| Pigment settling during storage | Use a higher viscosity LANDERCOLL grade (e.g., switch from HE30M to HE60M) to improve pigment suspension. |
| Paint drips or sags after application | Increase the HEC concentration or use a higher viscosity grade (e.g., switch from HE60M to HE100M) to enhance sag resistance. |
| Poor leveling and brush marks | Use a lower viscosity LANDERCOLL grade (e.g., switch from HE60M to LR) to improve flow and leveling properties. |
Slowly add LANDERCOLL HEC to water with vigorous agitation to prevent lumping. Using warm water can accelerate the process.
Continue mixing until the HEC is fully dissolved and the solution is clear and homogeneous.
Add the HEC solution to the paint formulation during the let-down phase.
Adjust the HEC concentration as needed to achieve the desired viscosity and performance characteristics.
