Low viscosity HPMC is widely used for self-leveling. Self-levelling is a very advanced construction technology. Due to the natural leveling of the entire floor with minimal interference from the construction personnel, the leveling and construction speed are greatly improved compared to the previous manual leveling process. In self-leveling, the dry-mixing time makes use of the excellent water retention capacity of hydroxypropyl methylcellulose. Since self-leveling requires a well-mixed mortar to be automatically leveled on the ground, the use of water-based materials is relatively large. Adding hydroxypropyl methylcellulose can control the water retention of the ground after pouring, water seepage is not obvious, and the dry ground has high strength and low shrinkage, thus greatly reducing cracks.
The chemical structure of MHEC mirrors that of HPMC. It encompasses hydroxyethyl groups linked to the hydroxyl groups within cellulose. The degree of substitution (DS) governs the quantity of hydroxyethyl groups incorporated, influencing MHEC's solubility, viscosity, and other intrinsic traits. MHEC remains stable under standard conditions and exhibits resistance to microbial degradation.
