Hpmc for construction

1. Hydroxypropyl Methyl Cellulose HPMC For Construction
Product properties
1.Water Retention: The water retention will be enhanced, which is helpful with such
problems as cement or gypsum construction material drying too fast and poor
hardening or cracking due to insufficient hydration.
2. Operationality: It can enhance the plasticity of mortar and improve the coating
efficiency in construction projects.
3. Adhesivity: It can make mortar attach to base material better since the plasticity
of mortar is enhanced.
4. Slip Resistance: It can prevent slipping problem between mortar and the base
material in construction project as a result of its thickening effect.
Application Performance :
(1)Water Solubility Soluble water in any proportion,the highest density depends on
viscosity,and solution does not be effected by PH value.
(2) Solubility in Organic solvent HPMC can dissolve in some organic solvents or
organic aqueous solutions such as ethylidene chloride,alcohol ones.
(3) Heat Gelling When their aqueous solutions are heated to a certain temperature,
reversible reaction may occur,but its fast gelling can be controlled.
(4)Non-ion Electric Charge HPMC is non-ion cellulose ether,does not complex with
metal ions or result in insoluble precipitations.
(5) Thickening Its water solution provides thickening effect whoich has to do with
viscosity,density and system.
(6) Water-holding HPMC or its solution can absorb and hold moisture.
(7) Film-forming HPMC can be made into smooth,tough and elastic film which offers
excellent oil resistance and antioxidancy.
(8) Anti-enzyme HPMC and its solution have good resistance to enzyme,and offer
good viscosity stability.
(9) PH Stability HPMC is stable in acid and alkali,no effect within PH3-11.
(10) Surface Tension HPMC in solution provides surface activity,playing a role of
emulsification and protection of gels.

2. (11) Inertness of Metabolism Used as additive of food and medicine,it is
non-nutritious, heatless, does not change metabolism.
(12) Dispersiveness HPMC can reduce interface tension,making dispersive phases
disperse to size-suitable granules.
(13)Coherence Can be used as pigment,adhesive agent for paper,also used in coating
and cohesive auxiliary material.
(14) Lubricity Can be used for rubber,asbestos,cement and ceramics to reduce
friction and improve the pumping-adaptability of cement slurrry.
(15) Suspension-Assistance Can prevent solid granules from setting down.
(16) Emulsification Owing to reducing surface tension,it can stabilize emulsion.
(17) Protection of Gels A protective layer forms on the surface of the dispersed drops.
which prevents drops from agglomerating,thus stabilizing gels.

Namely, 2% water solution will form gelation at 60%.
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

4. 3 Better work-ability: lubricity and plasticity of plaster is ensured, mortar can be
applied easier and quicker
Cement Based Plaster
1 Easy dry mix formulation due to cold water solubility: lump formation can be easily
avoided, ideal for heavy tiles.
2 Good water retention: prevention of fluid loss to the substrates, the appropriate
water content is kept in mixture which guarantees longer concreting time
3 Increased water demand: increased open time, expanded spry area and more
economical formulation
4 Easier spreading and improved sagging resistance due to improved consistency
Exterior Heat Insulation System ( EIFS )
1 Improved adhesion
2 Good wetting ability for EPS board and substrate
3 Reduced air entrainment and water uptake.
Self-leveling
1 Protection from water exudation and material sedimentation
2 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
3 Sag resistance: improved mortar bonding ability
Gypsum Based Plaster
1 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
1 Excellent workability for ceramic molding due to lubricity and plasticity
2 Compact texture and smooth surface of ceramic product due to negligible ash
content
