MIKUR supplies Hydroxypropyl Methylcellulose (HPMC), a high-performance non-ionic cellulose ether made primarily from high-quality natural plant fiber (refined cotton) using advanced manufacturing processes. HPMC is typically a white or off-white powder with good water solubility, stability, compatibility and water-retention properties. It is widely used in building materials and various water-based formulations.
HPMC powder can disperse and dissolve rapidly in water and provides thickening, water retention, rheology control, suspension and stabilization in different formulations. An appropriate dosage can improve workability, water retention, sag resistance, open time and formulation stability, helping enhance overall product performance.
In building materials, hydroxypropyl methylcellulose is widely used in tile adhesives, wall putty, plastering mortars, dry-mix mortars, self-leveling mortars, tile grouts, and other cement-based and gypsum-based materials. In tile adhesives, HPMC helps improve water retention, workability and bonding performance; in putty and plastering mortars, it improves workability, water retention and sag resistance; in self-leveling products, it can be selected to adjust rheology and formulation stability according to application requirements.
Beyond building materials, HPMC can also be used in water-based coatings, adhesives, daily chemical products and other water-based systems. With its effective thickening, rheology-control and stabilizing properties, HPMC helps meet different requirements for viscosity control, formulation stability and application performance.
Different HPMC grades and viscosity levels are suited to different applications. MIKUR can recommend suitable HPMC products according to the application, formulation system, substrate and target performance, helping customers meet requirements for viscosity, water retention, workability, open time, sag resistance and formulation stability.
As a professional HPMC manufacturer and supplier, MIKUR provides not only hydroxypropyl methylcellulose products but also product samples, application testing and formulation support. Customers can select an appropriate HPMC grade for their specific product system and determine the suitable specification and dosage through practical testing.
Whether for tile adhesives, wall putty, plastering mortars, dry-mix mortars, self-leveling mortars, water-based coatings or adhesives, selecting the right HPMC requires consideration of the formulation, application requirements and target performance. MIKUR provides professional HPMC cellulose ether solutions for different applications.

Retention for Improved Workability
Water Retention and Thickening for Improved Mortar Performance
MIKUR Hydroxypropyl Methylcellulose (HPMC) is a high-performance non-ionic cellulose ether widely used in cement-based and gypsum-based building materials. When dissolved in water, HPMC forms a viscous colloidal system. Through water retention, thickening and rheology control, it slows rapid water loss, provides a suitable moisture environment for cement and gypsum hydration, and improves mortar workability and formulation stability.
Key Advantages
Stable Water Retention and Improved Sag Resistance
For applications in tropical monsoon and hot, humid conditions, MIKUR selects HPMC grades with suitable viscosity, substitution characteristics and gel temperature to help cement-based and gypsum-based materials maintain stable water retention, thickening and rheological performance.

| 建议剂量 | 0.25%–0.40% |
| Key Performance | Water Retention, Thickening, Sag Resistance, Application Stability |
Key Advantages
Scientific Formulation: Balancing Water Retention, Sag Resistance, Workability and Water Resistance
MIKUR HPMC formulation solutions combine HPMC with starch ether, water-repellent agents, bentonite and other functional additives. Formulations are adjusted according to the mortar system and target performance.
Through synergy between functional components, the formulation can maintain water retention while further improving sag resistance, workability, water resistance and formulation stability. It is suitable for tile adhesives, wall putty, plastering mortars, waterproof mortars, repair mortars and other building materials.
By controlling the ratio of each component, the formulation avoids relying solely on higher HPMC viscosity or dosage and achieves a more practical balance between water retention, workability, sag resistance, water resistance and cost.
Different mortar products have different requirements for HPMC and functional additives. MIKUR can provide product selection, sample testing and formulation optimization based on the product type, raw materials, application method and target performance.

HPMC (Hydroxypropyl Methylcellulose) is widely used in wall putty, tile adhesives, insulation mortars, plastering mortars, dry-mix mortars and gypsum-based materials. It mainly provides water retention, thickening and rheology control to optimize mortar workability and formulation stability.
Excellent Water Retention and Reduced Moisture Loss
HPMC slows rapid water loss, providing a stable moisture environment for cement and gypsum hydration. Typical reference viscosity is 150,000–200,000 mPa·s, with a dosage of approximately 0.25%–0.40%, subject to formulation adjustment.
Thickening and Sag Resistance for Better Application
HPMC improves mortar cohesion and structural stability, making putty, plastering mortars and tile adhesives easier to apply. For systems requiring stronger sag resistance, HPMC can be combined with starch ether; a reference ratio is HPMC : starch ether ≈ 10:1.
Formulation Synergy for Optimized Performance
Depending on product requirements, HPMC can be combined with starch ether, powdered silane water-repellent agents, bentonite and other functional additives to improve thixotropy, sag resistance, water resistance and formulation stability.
HPMC (hydroxypropyl methylcellulose) is mainly used to improve water retention, thickening, rheology, sag resistance and workability in building materials. It is widely used in tile adhesives, wall putty, plastering mortars, insulation mortars and gypsum-based materials.
Not necessarily. Higher-viscosity HPMC generally provides stronger thickening and water retention, but excessive viscosity may affect mortar flow and application feel. Select viscosity according to the product type, formulation system and application requirements.
Dosage depends on mortar type, binder content, aggregate grading and target performance. For some building mortars, 0.25%–0.40% can be used as a reference range; the actual dosage should be optimized through formulation testing.
Consider water retention, thickening and workability together. For some mortars requiring stronger water retention and thickening, viscosity levels such as 150,000–200,000 mPa·s may be considered; final selection should be based on practical testing.
HPMC can improve water retention, application feel, open time, cohesion and slip resistance in tile adhesives, helping provide more stable installation performance.
