It is widel used as thickener, adhesive, water preserving agent, film-forming agent in construction, building materials, dispersion coating, wallpaper paste, polymerization aids, leathers, printing ink and paper making etc.l also used in and daily-use chemicals.
Redispersible Polymer Powder is a specifically designed polycarboxylate superplasticizer which exhibits excellent dispersion performance while maintaining good retention effects due to our cutting-edge processing technique;
Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose.
The redispersible polymer powder (RDP) is a water soluble redispersible powder. It is a copolymer of ethylene and vinyl acetate. It is easily soluble in water and forms an emulsion quickly.
Construction Grade Chemical Additives HPMC
In finishing a large self-leveled surface, curing becomes problematic, since any coverings will cause surface blemishes. Thus no cover could be used for curing.
Because of the large surface area to volume ratio, incomplete hydration due to evaporation becomes one primary causes of premature strength failure of self-leveling compounds.
Some times corrections need to be made after EPS or XPS panels are placed. PENSDA® HPMC can give workers prolonged open time to correct such mistakes without having to clean up old adhesive and applying new adhesives.
For insulating plasters, PENSDA® HPMC's shear-thinning behavior imparts pump-ability as well as good segregation control, especially these slightly larger insulating particles are much lighter than the fine sand and cement particles.
Compared to unmodified gypsum, PENSDA® HPMC modified building materials can drastically increase the water demand, which increases both working time and volumetric yield, thus making the formulation much more economic.
The shear-thinning and air-entraining properties of PENSDA® HPMC give HPMC modified tile adhesives a better workability, as well as higher work efficiency, from yield/coverage and faster tiling sequence stand points.

HPMC
Self-leveling floor materials
(1) The viscosity of HPMC has the effect of anti precipitation.
(2) HPMC can enhance the product liquidity and pumpability, so as to improve the efficiency of the flooring.

Using HPMC, tile adhesive will easy to mix with water without lump appeared and saving time. Due to the more rapid and efficient operation, we can improve the workability and reduce the cost.
The plasticity function possessed by the thermoplastic resin of Redispersible Polymer powder can overcome the flatulence damage for cement mortar materials brought by temperature difference changes.
Prevents Segregation and Bleeding
PENSDA® HPMC is a wonderful suspension aid. At low viscosities, it can provide solid particle suspension along with good flow-ability, preventing segregation and bleeding.
