Building materials grade HPMC is specifically designed for building material formulations such as dry-mixed mortar, putty powder, tile adhesive, and gypsum products. It is a non-ionic water-soluble polymer. It has excellent water retention, thickening, workability, and adhesion properties, and can effectively improve the workability and stability of inorganic cementitious systems, adapting to different climates and construction conditions.

Key Features and Performance

• Strong water retention: Prevents the substrate from losing water too quickly, avoiding problems such as drying cracks and powdering.

• Improved workability: Improves the lubricity and workability of mortar, reducing construction fatigue.

• Enhanced bonding strength: Improves bonding strength in systems such as tile adhesives and exterior wall insulation.

• Good alkali resistance: Performs stably in alkaline systems such as cement and gypsum.

• Strong climate adaptability: Suitable for use in different environments such as high temperatures, dryness, or humidity.

Main Functionsfont

• Extend workability time

• Improve mortar water retention and uniformity

• Enhance bond strength and resistance to sagging

• Improve surface smoothness of the finished product

Usage Recommendations

• Viscosity selection: 40,000–100,000 (depending on formulation requirements)

• Addition rate: 0.2%–0.6% (based on dry powder weight)

Packaging and Storage/Transportation Precautions

Coated polypropylene woven bags, net weight per bag: 25 kg. Protect from direct sunlight, rain, and moisture during storage and transportation.

Construction-grade hydroxypropyl methylcellulose is an indispensable high-performance additive in modern building materials, significantly improving construction performance and finished product quality.

• Tile adhesive/grout

Enhances bonding strength, prevents tile detachment and hollow sounds, and improves construction smoothness.

• Putty powder/gypsum-based products

Improves application feel, prevents sagging, and enhances surface flatness.

• Dry-mixed mortar (plastering, masonry, insulation, etc.)

Extends workability time, ensures mortar uniformity, and improves construction efficiency.

• External wall insulation systems

Enhances bonding strength between insulation boards and mortar layers, and improves system stability.

• Waterproof mortar

Improves density and durability, and reduces the risk of water penetration.
