Hydroxypropyl Methylcellulose

Overview of Hydroxypropyl Methylcellulose

Concreteandmore’s Hydroxypropyl Methylcellulose (HPMC) is a high-performance non-ionic cellulose ether, specially processed from natural plant cellulose. It is widely used as a key additive in concrete and mortar, with excellent thickening, water-retention, film-forming and rheological properties. Our HPMC effectively solves the problems of poor water retention, easy segregation and low workability of cement-based materials, improves the bond strength and durability of concrete/mortar, and ensures smooth construction, suitable for various construction scenarios and climate conditions around the world.

Features of Hydroxypropyl Methylcellulose

• Excellent Water Retention: Effectively locks water in concrete/mortar, reduces water loss, prevents surface cracking and improves the strength of hardened materials.
• Strong Thickening & Rheological Control: Significantly improves the viscosity of cement paste, enhances cohesion, prevents segregation and bleeding, and optimizes construction workability.
• Good Film-Forming Property: Forms a uniform and tough film on the surface of concrete/mortar, improving impermeability, weather resistance and bond strength.
• Non-Ionic & Good Compatibility: Non-ionic structure, compatible with various cement types, water reducers, defoamers and other admixtures, no adverse reactions.
• High Purity & Stability: High cellulose content, low impurity, stable performance in a wide pH range (3-11), non-toxic, odorless and environmentally friendly.

Applications of Hydroxypropyl Methylcellulose

Concreteandmore’s Hydroxypropyl Methylcellulose (HPMC) is widely used in cement-based materials and construction projects, focusing on water retention, thickening and bond enhancement:

• Building Mortar: Used in tile adhesive, wall putty, waterproof mortar and masonry mortar, improving water retention, bond strength and workability.
• Concrete: Applied to self-leveling concrete, ready-mix concrete and shotcrete, preventing segregation, improving cohesion and construction performance.
• Gypsum Products: Used in gypsum board, gypsum putty and gypsum mortar, enhancing water retention and preventing cracking.
• Waterproof Coating: As a thickener and stabilizer in waterproof coatings, improving film-forming property and impermeability.
• Other Cement-Based Materials: Suitable for grouting materials, repair mortar and thermal insulation mortar, ensuring product stability and construction effect.

FAQs of Hydroxypropyl Methylcellulose

1.What is the role of HPMC in concrete?

It provides water retention, thickening and cohesion, prevents water loss and segregation, improves workability and bond strength of concrete/mortar.

2.How to choose the right viscosity of HPMC?

High viscosity (≥100000 mPa·s) for putty/waterproof mortar; medium viscosity (10000-50000 mPa·s) for tile adhesive; low viscosity for concrete.

3.How to use HPMC in construction?

Mix HPMC powder evenly with cement, sand and other dry materials first, then add water and stir thoroughly to ensure uniform dispersion.

4.Will HPMC affect concrete setting time?

Proper dosage will not significantly affect setting time; excessive dosage may slightly delay setting, which can be adjusted by dosage control.

5.Do you provide global supply and technical support?

Yes, we supply HPMC worldwide, with complete TDS and professional guidance to help you choose the right model and dosage.
