Product Description

HPMC is odorless, tasteless,non-toxic cellulose ethers produce from natural high molecula and protective colloid properties of surface activity and maintain moisture function properties ect.cellulose through series of chemical processing and achieved.It is white powder with good water solubility.It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel.

PHYSICAL AND CHEMICAL PROPERTIES:
1. Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh.
2. Charring temperature: 280-300ºC.
3. Bulk density: 0.25-0.70 g/cm3 (Usually around 0.5 g/cm3 )
4.Real specific gravity: 1.26-1.31.
5. Browning temperature: 190-200ºC.
6. Surface tension: (2% water solution) 42-56dyn.cm.
7. 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%.

Application:
1.HPMC For Wall Putty
Skim coat (also named by Wall Putty) is a decorative and functional trowelling plaster material for interior or external wall construction. It's function is to remove uneven defects on the surface of the base materials of wall, and eliminate the stress between different coating layers.
2.HPMC For EIFS
ETIFS/ETICS is a kind of thermal insulation structure which is installed on the surface of exterior wall. It can reduce the
influence of thermal bridge and deformation stress on the base wall. Senko products can give effectively improvement on the water retention, anti-stress cracking, open time, sag resistance, workability of the ETICS mortars.
3.HPMC for Tile Adhesive
The tile adhesive is physically mixed by cement, sand and accessories, and it is formulated differently in different countries or regions. There are various types of tiles and substrates, also the environment and trowel methods differ from one place to another , thus the performance requirements of cement tile adhesive are different.
4.HPMC for Self-leveling Mortar
Senko products gives the rheology and workability of the full range of flooring formulations. Improves ease of on-site application and ensuring exceptionally smooth, defect-free surfaces.
