Product Description
HPMC for Construction Industry
Hydroxypropyl methylcellulose (HPMC) is a versatile cellulose derivative widely used in construction materials. Its excellent water retention, thickening, bonding, and thixotropic properties enhance performance across various building applications.
Key Benefits
- Delays drying time for extended workability
- Prevents cracking in cementitious materials
- Reduces water seepage and improves water retention
- Enhances bond strength and workability
Primary Applications
Construction Materials
- Tile Adhesives & Putty (Grades: K100M, E15) - High water retention extends open time and enhances bond strength
- Cement Mortars (Grades: E5, E15) - Reduces cracking and improves fluidity/pumpability
- Self-Leveling Compounds (Grade: E5) - Low viscosity ensures superior flow and minimizes segregation
Core Application Scenarios
- Putty Powder (Interior/Exterior Walls)
- Various Cement Mortars
- Tile Adhesive (Tile Glue)
- Grout/Seam Grout
- Gypsum-based products
Quality Standards
Complies with Chinese Pharmacopoeia CP Edition specifications:
- Appearance: White or off-white powder, free of visible impurities
- Identification: Verified by TLC or UV spectroscopy
- Content Assay: Specific ratio of methyl and hydroxypropyl groups verified by GC or HPLC
- Moisture Content: Below 5% for storage stability
- pH: 6.0-8.0 for solution stability
- Viscosity: Specific range at 2% aqueous solution (25°C)
- Heavy Metal Content: ≤20 ppm (as lead)
