Paint manufacturers constantly seek innovative additives that improve product performance while maintaining cost efficiency. Landercoll® HEC (Hydroxyethyl Cellulose) stands out as a versatile, non-ionic thickener and rheology modifier. It’s widely recognized for enhancing viscosity, stability, and application properties in water-based and emulsion paints.
Landercoll® HEC is a cellulose derivative known for its water solubility and excellent thickening properties. It stabilizes formulations, ensuring pigments are evenly distributed and preventing sedimentation or delamination. Its key roles in paints include:
•Enhancing viscosity for better application control.
•Acting as a stabilizer to prevent pigment settling.
•Improving flow and leveling properties for smoother finishes.
•Preventing sagging during vertical applications.
1.Rheology Modification:
Landercoll® HEC enhances the paint’s rheological properties, ensuring smooth application and leveling. It minimizes the risk of brush marks or roller streaks.
2.Improved Stability:
By preventing phase separation, Landercoll® HEC ensures the paint remains uniform over time, extending shelf life.
3.Wide Compatibility:
This additive works seamlessly with a variety of paint systems, including latex paints and waterborne architectural coatings.
4.Environmental Benefits:
Being water-soluble, it aligns with eco-friendly formulations, reducing reliance on volatile organic compounds (VOCs).

1.Water-Based Paints:
Landercoll® HEC is highly effective in waterborne systems, ensuring smooth texture, excellent pigment dispersion, and long-term stability.
2. Latex Paints:
In latex paints, it provides superior thickening and sag resistance, making it easier to apply on vertical surfaces.
3.Emulsion Paints:
It prevents phase separation and ensures uniform pigment distribution, resulting in consistent color and finish.
4.Silicone Resin Paints:
For high-performance coatings like silicone resin paints, Landercoll® HEC ensures stability under extreme conditions.
Landercoll® HEC is often compared to thickeners like Natrosol® or HPMC. Its unique benefits include:
•Superior water retention, reducing shrinkage during drying.
•Better compatibility with diverse paint systems.
•Higher efficiency at lower concentrations, making it cost-effective.
