HPMC Used In Self-leveling Materials In Construction Industry
Product Description
Hydroxypropyl methylcellulose (HPMC) is used in self-leveling materials in construction industry
Product use
- Tile Adhesives & Putty (Grades: K100M, E15) - High water retention extends open time and enhances workability/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
Quality Standards (Chinese Pharmacopoeia CP Edition)
- Appearance: White or off-white powder with no odor or slight odor, 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)
Additional Applications
- Cosmetics & Coatings: Water-based paints (Grade E15) for uniform film formation; shampoo/toothpaste (Grade E5) for suspension enhancement
