CHINA Hydroxypropyl Methylcellulose Manufacturer

China HPMC Manufacturer & supplier - keyong

Wall putty, also known as a skim coat, is the essential preparatory layer before painting—composed of fine white cement-based powder. Incorporating high-quality HPMC additive from Keyong significantly enhances your wall putty’s durability, reducing cracking and aging, and ensuring a smooth, long-lasting finish.

At Keyong, we are a manufacturer-first HPMC producer, offering both standard and tailor-made grades to suit all your formulation needs.

Our production systems are underpinned by SGS and ISO 9001 certification, affirming our reliable quality systems and consistent excellence in product performance.

Behind every order is our dedicated R&D and customer support team—ready to help with grade selection, application advice, or formulation troubleshooting to ensure you get the precise solution you need.

Keyong HPMC – Enhance Your Construction Performance

  1. Superior Water Retention
    Keyong HPMC significantly improves water retention in your construction materials. It prevents rapid drying and poor hardening in cement and gypsum-based products, reducing the risk of cracks and extending open time for better workability.

  2. Effective Thickening
    Our HPMC enhances the viscosity of your formulations, ensuring optimal consistency and stability. This helps maintain high-quality performance throughout the application process.

  3. Anti-Slip Performance
    The thickening effect of HPMC prevents slippage during construction, providing a secure bond between mortar and the applied surfaces. Your projects stay safe and reliable.

  4. Improved Lubrication & Workability
    Keyong HPMC improves the workability and processability of cement-based materials, making application smoother and more efficient.

Customized HPMC Solutions
We offer tailored modified HPMC products to meet your specific project requirements. Our advanced laboratories and expert team are ready to develop customized formulas, helping you achieve the best results for every construction application.

HPMC Production Equipment Highlights

Advanced Etherification Reactors with DCS Control

Keyong’s production facility features multiple stainless-steel etherification reactors equipped with Distributed Control System (DCS) monitoring. This allows for precise control over reaction temperature, pressure, and duration—critical for achieving consistent viscosity and substitution levels in HPMC

Integrated Production Workflow (Crushing → Etherification → Refining → Mixing → Packaging)

Our plant follows an efficient, integrated workflow that includes raw material crushing, alkalization, etherification, powder refining, blending, and packaging. This streamlined process ensures uniform quality and high production throughput.

High-Precision Downstream Equipment: Filtration, Drying & Milling

After the chemical reaction, our HPMC slurry undergoes filtration (e.g., rotary pressure filters), controlled drying, and fine milling to produce homogeneous, powdery HPMC with minimal impurities—ideal for construction-grade and specialty applications

Keyong Hydroxypropyl Methylcellulose key application

Keyong HPMC excels as a thickener (enhancing viscosity), emulsifier/stabilizer, and film-forming agent across diverse sectors:

  • Construction: improves cohesion, water retention, and workability in wall putty, mortar, and tile adhesives;
  • Coatings & Paints: controls flow, prevents sagging, enhances stability;
  • Daily Chemicals & Oil Drilling: supports texture and suspension in personal care products and stabilizes drilling fluids.
