About LANDU Hydroxyethyl Cellulose (HEC)
Absolutely! Hydroxyethyl Cellulose (HEC) is a non-ionic, water-soluble polymer derived from cellulose. Think of it as the “secret sauce” that gives textured paint its desired thickness and stability. Chemically, HEC is created by reacting ethylene oxide with alkali-cellulose. This process introduces hydroxyethyl groups onto the cellulose backbone, making the polymer water-soluble and capable of forming viscous solutions. As LANDU, we’ve seen firsthand how impactful this seemingly simple ingredient can be.
In cost-sensitive formulations, LANDU economy-grade HEC provides essential thickening and stabilization, preventing pigment settling and ensuring adequate application properties.
For most general-purpose textured paints, LANDU standard-grade HEC offers a balanced combination of viscosity control, water retention, and workability.
In high-end textured paints, LANDU premium-grade HEC contributes to exceptional crack resistance, enhanced durability, and superior aesthetic appeal. These paints often contain higher concentrations of HEC or our modified HEC grades.
HEC is not just a thickener; it’s a multi-functional additive that elevates the performance of textured paint. Here’s a closer look at its key advantages:
HEC forms a protective film that slows down water evaporation, prolonging the paint’s open time.
HEC prevents the paint from drying out too quickly, giving painters more time to achieve the desired texture.
HEC keeps pigments and aggregates evenly dispersed throughout the paint, preventing settling and ensuring consistent color and texture.
HEC enhances the paint’s flow and leveling properties, making it easier to apply and create desired textures.
At LANDU, we specialize in providing high-quality cellulose ethers for a wide range of applications, including textured paints. Our LANDERCOLL line of HEC products is engineered to deliver exceptional performance and consistency.

Trowel-applied textures often require higher viscosity HEC to prevent sagging.
In hot and dry climates, higher concentrations of HEC may be needed to improve water retention.
| Textured Paint Type | Application Method | Climate | Recommended LANDERCOLL Grade |
|---|---|---|---|
| Fine Texture | Spray | Moderate | HE30M |
| Medium Texture | Roller | Moderate | HE100M |
| Coarse Texture | Trowel | Moderate | MEB6000 |
| Heavy Texture | Trowel | Hot | MEB7000 |
| Fine Texture | Spray | Hot | MHE2000 |
| Problem | Solution |
|---|---|
| Paint is too thin and runny. | Increase the concentration of HEC or switch to a higher viscosity grade (e.g., from LANDERCOLL HE30M to HE60M). |
| Paint cracks after drying. | Increase the concentration of HEC to improve water retention and reduce premature drying. |
| Pigments settle out of the paint. | Use a higher viscosity grade of HEC to enhance suspension properties and prevent pigment settling. |
For best results, follow these guidelines:
Use deionized water for preparing the HEC solution to minimize the risk of contamination and ensure consistent performance.
Add HEC to water while stirring vigorously to prevent lumping.
Allow the HEC solution to hydrate for at least 20-30 minutes before adding it to the paint formulation.
Ensure the pH of the paint formulation is within the recommended range (typically 7-9) for optimal HEC performance.
