Hydroxyethyl Methyl Cellulose HPMC For Construction
Hydroxy Propyl Methyl Cellulose HPMC Used for Wall Putty
Building Material/Adhesive HPMC Hydroxypropyl Methyl Cellulose Ether
HPMC - Hydroxypropyl methyl cellulose
HS Code: 3912, 3900
HPMC Hydroxypropyl MethylCellulose has thermal gelation properties, so after heating the aqueous solution will precipitate and form gels, and dissolve again after cooling. Products of different specifications have different gelling temperatures. Its solubility varies with the viscosity, and the lower the viscosity is, the greater the solubility will be. There are some differences in the properties of Hydroxypropyl MethylCellulose of different specifications. The dissolution of HPMC Hydroxypropyl MethylCellulose in water is not affected by the pH value.
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 ):
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.
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
Excellent workability for ceramic molding due to lubricity and plasticity
Compact texture and smooth surface of ceramic product due to negligible ash content
