Hydroxyethyl Cellulose (HEC)
Exceptional Water Retention: Possesses water-retention capabilities twice that of methylcellulose (MC), significantly reducing water loss, cracking, and hollowing in mortars and putties.
Thickening and Stabilization: Non-ionic in nature; exhibits excellent resistance to salts and pH variations (2–12), maintaining stable viscosity even in high-salinity environments. Highly compatible with HPMC, PVA, and starch ethers.
Flexible Film Formation: Forms a transparent, flexible, and water-resistant film, thereby enhancing bonding strength and crack resistance.
Mold Resistance and Durability: A natural cellulose ether that resists microbial degradation, ensuring a long shelf life.

Interior & Exterior Wall Putty / Leveling Mortar: Provides thickening, water retention, crack resistance, and anti-powdering properties; ensures smooth application and excellent sandability; dosage: 0.3–0.8%.
Tile Adhesives / Grouts: Enhances bond strength, slip resistance, and water retention; minimizes hollowing and detachment; dosage: 0.2–0.5%.
Gypsum-based Products (Paired with Retarders): Offers retardation, water retention, and increased flexibility; improves workability and prevents cracking; yields optimal results when compounded with gypsum retarders.
Thermal Insulation Mortar / Interface Agents: Provides thickening and water retention; enhances workability and adhesion.
Latex Paints / Water-based Coatings: Provides thickening, leveling, and anti-settling properties; stabilizes emulsions and improves "open-can" appearance.
Packaging:25 kg/bag
Note： HEC should be stored in a dry, well-ventilated area, sheltered from direct sunlight and moisture, with attention required during transportation to protect it from rain and other weather elements.
