* Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh. * Charring temperature: 280-300℃. * Bulk density: 0.25-0.70 g/cm3 (Usually around 0.5 g/cm3 ) * Real specific gravity: 1.26-1.31. * Browning temperature: 190-200℃. * Surface tension: (2% water solution) 42-56dyn.cm. * Properties: Dissolved in water and some organic solvent such as ethanol. propyl alcohol. ethylene chloride, the water solution is of surface activity. It is a nonionic surface active agent. Gelation temperature is different for different grades. For example, among 60RT Hydroxypropyl Methylcellulose, 60 is gelation temperature, Namely, 2% water solution will form gelation at 60%.

Performance in joint cover: In joint cover, the addition amount of HPMC is very low, only 0.1%-1%, but it plays an irreplaceable role and can significantly improve the water retention, fluidity and lubricity of building materials. Building materials added with HPMC are easier to mix and use, improve the work efficiency of construction workers, extend the open time, improve the bonding strength, and form a smooth and delicate surface coating. Joint filler application guide • Increase the bonding strength of wet mortar • Good water retention can make sure the cement and other additives fully hydrated which can increase the woking time and reduce the risk of cracking.Packaging and storage: 25 kg/bag Note: The Joint filler HPMC is packaged in polypropylene woven bags, each with a net weight of 25kg. When storing, place in a ventilated and dry place indoors, pay attention to moisture. Pay attention to rain and sun protection during transportation.● Packaging for products over 1 tonne 25kg /paper bags with PE inner. Cellulose ethers (HPMC, HEMC): 20'FCL:10 tons with pallets or 12 tons without pallets. 40'FCL:20 tons with pallets or 24 tons without pallets.● Sample packaging 500g sample in airtight plastic bag and then packed in a sealed aluminium foil bag
