Application
• HEMC / MHEC (Hydroxyethyl Methyl Cellulose / Methyl Hydroxyethyl Cellulose)
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.
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.
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
Industrial waterborne coatings
Decorative and textured finishes
