HPMC for construction
Hydroxypropyl Methyl Cellulose is a non-ionic cellulose ether made from natural high polymer cellulose. It is an odourless, tasteless and non-toxic white powder, which can be dissolved in cold water to form a transparent viscous solution.
Hydroxypropyl Methyl Cellulose can be used in various building materials,HPMC for construction:
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
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
