Overview
Self-leveling mortar is a specialized cementitious product designed to flow and spread easily, forming a smooth, level surface without the need for extensive troweling. It’s commonly used to prepare subfloors before installing tiles, vinyl, or other floor coverings. To achieve the right balance of flowability, setting time, and surface strength, modern formulations depend on high-quality cellulose ethers such as HPMC and MHEC.
At Hehui Chemical, we offer high-performance HPMC and MHEC tailored for self-leveling compounds. Our cellulose ethers are engineered to provide excellent water retention, flow control, anti-segregation properties, and surface smoothness — making them ideal for both manual and pump-applied systems.
Water Retention
Prevents rapid moisture loss, ensures full hydration of cement, and helps avoid cracks or surface dusting.
Rheology & Flow Control
Provides consistent viscosity and thixotropic behavior, allowing the mortar to self-spread smoothly while preventing bleeding and segregation.
Open Time & Workability
Extends working time, enabling larger areas to be leveled efficiently without cold joints or uneven sections.
Improved Surface Finish
Reduces air entrainment and enhances surface density, delivering a smooth, defect-free finish ideal for further flooring applications.
Anti-Shrinkage and Durability
Enhances dimensional stability, minimizes shrinkage during drying, and improves long-term durability of the subfloor layer.
Excellent viscosity stability and dispersion in water
Designed for rapid mixing and smooth flow performance
Compatible with all types of cement and gypsum-based systems
Reduces dusting and improves surface integrity
Produced in ISO-certified facilities with strict quality standards
Packaging: 25kg kraft bags with PE inner lining
Shelf Life: 2 years in dry, sealed conditions
Storage: Keep away from moisture and store in a cool, dry place
