Core Functions in Coatings
Rheology Modification (Thickening & Anti-sagging)
Provides pseudoplasticity (shear thinning): viscosity decreases during brushing or spraying for easy construction; viscosity recovers at rest to prevent sagging.
Controls coating consistency, enhances leveling and reduces brush marks.
Water Retention & Prolonging Open Time
Water retention rate ≥95%, delaying water evaporation and extending the operable time.
Prevents cracking and peeling caused by rapid drying of coatings.
Stabilization of Pigments and Fillers
Excellent suspension and dispersion properties to prevent pigment sedimentation and delamination.
Avoids floating color and flooding, ensuring uniform color.
Improving Coating Film Performance
Assists film formation, making the coating film continuous, smooth and dense.
Enhances adhesion, scrub resistance and durability.
Construction-friendliness
Reduces splashing and dripping during brushing.
Lowers construction resistance for a smooth application feel.
Main Application Fields
Interior and exterior wall latex paints (mainstream application)
Water-based wood paints and industrial water-based paints
Thick-bodied coatings, texture coatings and real stone paints
Water-resistant putties, lime-based coatings (advantage in alkaline systems)
Waterproof coatings and roof coatings
Dosage and Application Suggestions
Dosage: 0.2%~0.5% (based on total coating mass)
Viscosity Selection:
Ordinary latex paints: low to medium viscosity (30,000~50,000 mPa·s)
Thick-bodied/texture coatings: medium to high viscosity (80,000~100,000 mPa·s)
Dissolution Method: Premix with powder before adding water, or slowly sprinkle under high-speed stirring to avoid caking.
Product Advantages
HEMC is the preferred cellulose ether for high-performance water-based coatings, especially suitable for high-temperature, dry and high-alkaline environments. It delivers balanced performance in water retention, anti-sagging, leveling and stabilization, effectively improving coating quality and reducing rework rates.
