Factory Cheap Price methyl cellulose hpmc construction materials for dry mix mortar
Product Description
Hydroxypropyl methylcellulose (INN name: Hypromellose), also simplified as hydroxypropyl methylcellulose (HPMC), is a variety of nonionic cellulose mixed ethers. It is a semi-synthetic, inactive, viscoelastic polymer .This product is industrial grade HPMC, mainly used as the dispersing agent for PVC production and as the main assistant used in producing PVC suspension polymerization.
It is also used as thickener, stabilizer, emulsifier, excipient, water retention agent, and film-forming agent etc.in producing petrochemicals, building materials, paint removers, agricultural chemicals, inks, textiles, ceramics, paper. cosmetics and other products.

Features
Application
Typical Applications of HPMC:
Tile Adhesive
Good water retention: prolonged opening time will make tiling more efficient.
Improved adhesion and sliding resistance: especially for heavy tiles.
Better workability: lubricity and plasticity of plaster is ensured, mortar can be applied easier and quicker.
Cement Plaster / Dry mix mortar
Easy dry mix formula 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.
Wall putty
Water retention: maximized water content in slurry.
Anti-sagging: when spreading a thicker coat corrugation can be avoided.
Increased mortar yield: depending on the weight of the dry mixture and appropriate formulation ,HPMC can increase the mortar volume.
Exterior Insulation and Finish System ( EIFS )
Improved adhesion.
Good wetting ability for EPS board and substrate.
Reduced air entrancement and water uptake.
Self-leveling
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
Better workability: proper thickness and plasticity.
