Water-Based Paint & Coating Application

Recommended Additive:

• HEMC / MHEC (Hydroxyethyl Methyl Cellulose / Methyl Hydroxyethyl Cellulose)


Good Performance with HEMC for Water-Based Paints

Water-based paints and coatings are increasingly favored in today's environmentally conscious market. With low VOC emissions, non-toxic formulations, and easy cleanup, they offer a safer and more sustainable alternative to solvent-based systems. However, formulating high-performance water-based coatings requires advanced additives to ensure proper viscosity, pigment suspension, and application behavior.

Hehui Chemical's high-purity HEMC is specially developed to meet the demanding needs of modern water-based coating systems. As a highly efficient thickener, stabilizer, and flow modifier, our HEMC helps improve consistency, application performance, and long-term storage stability.

Why Use HEMC in Water-Based Paint & Coating?

Viscosity Control & Rheology Optimization

HEMC imparts excellent viscosity and flow control, improving the paint's brushability, rollability, and spray application while maintaining anti-sag properties.


Improved Pigment Suspension

Effectively prevents pigment settling and ensures uniform color distribution, enhancing gloss, hiding power, and color consistency.


Superior Film Formation

Supports smooth film build-up with minimal brush or roller marks. Ideal for both interior and exterior paints with enhanced surface finish.


Anti-Spatter & Anti-Splash

Reduces splattering during application, especially with rollers, contributing to cleaner work and higher efficiency.


Better Storage Stability

Maintains product consistency over time and under temperature variations, extending shelf life and minimizing viscosity drift.

Typical Applications

Hehui HEMC is suitable for a wide range of water-based coating systems:

Interior and exterior wall paints

Emulsion paints

Primers and sealers

Acrylic-based coatings
