Inside Kingmax Factory: How HPMC, MHEC, and RDP Are Made

1. Raw Material Selection: The Foundation of Quality

Every high-quality additive starts with carefully selected raw materials. Kingmax ensures:

• Consistent and high-purity cellulose sources

• Strict inspection and verification before production

• Controlled storage to prevent contamination or degradation

This foundation guarantees predictable performance and batch-to-batch consistency.

2. HPMC Production: Advanced Etherification

Hydroxypropyl Methylcellulose (HPMC) is produced through a controlled etherification process:

• Cellulose is reacted with methyl and hydroxypropyl groups under precise conditions

• Automated control systems maintain consistent substitution levels and viscosity

• The result is an HPMC that offers high water retention, smooth workability, and extended open time

Advanced monitoring ensures each batch meets strict performance specifications.

3. MHEC Production: Rheology and Stability

Methyl Hydroxyethyl Cellulose (MHEC) is designed to improve flow, viscosity, and stability in coatings and construction materials:

• Controlled etherification produces uniform molecular structure

• Precision drying and grinding ensure consistent particle size

• The final product dissolves easily and provides excellent anti-sagging and pigment stabilization

Kingmax MHEC supports smooth application and long-term coating performance.

4. RDP Production: Redispersible Polymer Powder

Redispersible Polymer Powder (RDP) enhances bond strength, flexibility, and durability in mortars:

• Polymers are polymerized and then spray-dried into fine powders

• RDP particles re-disperse easily in water to form a flexible polymer network

• This network improves adhesion, crack resistance, and cohesion in cementitious materials

The process ensures that RDP performs consistently in various construction applications.

5. Precision Drying, Grinding, and Blending

After the main reactions, additives undergo precision drying, grinding, and blending:

• Ensures uniform moisture content and particle size

• Guarantees easy dispersion in water and homogenous mixing

• Optimizes performance in tile adhesives, wall putty, mortars, and coatings

This step is crucial for application-ready, high-performance products.

6. Comprehensive Quality Control

Kingmax applies strict quality control at every stage:

• Laboratory testing for viscosity, water retention, and particle size

• Batch-to-batch consistency verification

• Compliance with international standards for construction materials

Only products meeting all specifications are released for global supply.

7. Packaging and Supply

Finished additives are carefully packaged to maintain quality during storage and transportation:

• Moisture-proof and secure packaging

• Ready for global shipping and industrial-scale applications

• Reliable supply for long-term projects

This ensures customers receive consistent, high-quality additives wherever they are.
