Cellulose ether

Hydroxypropyl Methy Cellulose HPMC Tile Cement Adhesive
High Viscosity Cellulose Ether HPMC From China Factory
Cellulose Ether HPMC for Construction Mortar
Cellulose ether HPMC is a non-ionic, water soluble white powder. It can be used as an agent of water retention, thickening, adhesive and dispersing, and also plays a role of protective colloid, stabilizer,suspension and film forming.
cellulose ether HPMC is widely used in tile adhesives, wall putty/skim coat, plaster/render mortars, EIFS, tile grouts, joint filler, self leveling compounds, detergents, ready to use paints and coatings, etc.
Hydroxy Propyl Methyl Cellulose  ( HPMC ) 
CAS No.: 9004-65-3
1. water-soluble, non-ionic cellulose cellulose ether
2. odorless, tasteless, non-toxic, white powder
3. dissolved in cold water, forming a clear or slightly solution
4.properties of thickening, binding, dispersing, emulsifying, film-forming, suspension, adsorption,       gel, surface activity, water retention and protective colloid.
* Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh.
* Charring temperature: 280-300ºC.
* Bulk density: 0.25-0.70 g/cm3 (Usually around 0.5 g/cm3 )
* Real specific gravity: 1.26-1.31.
* Browning temperature: 190-200ºC.
* 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%.

Cellulose ether Application: 

Tile Adhesive:
1 Good water retention: it can prolonged opening time , to make tiling more efficient 2 Improved adhesion and sliding resistance especially for heavy tiles
3 Better work-ability: lubricity and plasticity of plaster is ensured, mortar can be applied easier and quicker
Cement Based Plaster:
Easy dry mix formulation due to cold water solubility: lump formation can be easily avoided, ideal for heavy tiles.
Good water retention: prevention of fluid loss to the substrates, the appropriate water content is kept in mixture which guarantees longer concreting time
Increased water demand: increased open time, expanded spry area and more economical formulation
Easier spreading and improved sagging resistance due to improved consistency
Exterior Heat Insulation System ( EIFS ):
Improved adhesion
Good wetting ability for EPS board and substrate 3 Reduced air entrainment and water uptake.
Protection from water exudation and material sedimentation
No effect on slurry fluidity with low viscosity HPMC, while its water retention characteristics improve the finish performance on the surface.  
Crack Filler:
1 Better workability: proper thickness and plasticity 2 Water retention ensures prolonged work time
2. Sag resistance: improved mortar bonding ability
Gypsum Based Plaster:
Water retention: maximized water content in slurry ensures complete gypsum concretion.
      2.Anti-sagging: when spreading a thicker coat corrugation can be avoided ( careful when air is entrained )
      3.Increased mortar yield: depending on the weight of the dry mixture and appropriate formulation HPMC can increase the mortar
Ceramic Extrusion:
Excellent workability for ceramic molding due to lubricity and plasticity
Compact texture and smooth surface of ceramic product due to negligible ash content
