HEMC Yüksek Performanslı Selüloz Eterleri Fayans Yapıştırıcıları, Harçlar ve Sıvalar için
Meeting the Demands of Next-Generation Building Materials
In today's fast-paced construction environment, the expectation for building materials has evolved far beyond traditional standards. Contractors, manufacturers, and developers alike are demanding products that deliver not only strength and durability but also enhanced workability, improved performance under diverse climate conditions, and compliance with increasingly strict environmental regulations.
Landercoll® Hydroxyethyl Methyl Cellulose (HEMC/MHEC) was engineered to answer these demands. When integrated into construction products, Landercoll® HEMC transforms performance — extending open time, increasing water retention, and enhancing bonding strength — all critical parameters for professionals who refuse to compromise on quality.
Premium HEMC Product
High-performance cellulose ether for construction
Understanding Hydroxyethyl Methyl Cellulose (HEMC/MHEC)
Hydroxyethyl Methyl Cellulose is a non-ionic cellulose ether derived from refined cotton and wood pulp. The hydroxyethyl and methyl groups introduced during etherification create a polymer that interacts predictably with water, cement, gypsum, and other binder systems. As a non-ionic polymer, Landercoll® HEMC is chemically stable across a wide pH range, making it suitable for various construction applications without risk of premature degradation.
Key Advantages for Construction Applications
Superior Water Retention
Molecular structure slows water evaporation, maintaining optimal hydration for cement and gypsum systems, preventing premature drying.
Enhanced Workability
Modifies viscosity and thixotropic behavior, allowing for smoother troweling, easier spreading, and consistent layer formation.
Extended Open Time
Longer open time enables workers to adjust tiles or smooth surfaces without rushing, reducing error rates and material wastage.
Improved Bonding Strength
Better hydration and adhesion promotion result in finished surfaces with superior tensile and shear strength performance.
Eco-Friendly & Safe
Odorless and non-toxic, supporting healthier working conditions and reducing environmental impact through renewable materials.
