Hydroxypropyl methylcellulose hpmc cellulose ether
CAS NO:9004-65-3
HS CODE: 3912390000
Hydroxypropyl methylcellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose. It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additives.To meet the needs of environmental protection, Our product with high water retention, dispersion, good fineness, good work ability, easy dissolution characteristics.It suitable for dry mortar building, both inside and outside wall putty powder milk (cream), adhesives, caulks, interface agents, coatings, self-leveling agent of new building materials.
And my company has the advanced method of liquid phase reaction kettle, adopt domestic most advanced technology to produce hydroxypropyl methyl cellulose.
It has thickening, adhesion, dispersing, emulsifying, film, suspended, adsorption, gel, and protetive colloid properties of surface activity and maintain moisture function properties ect.
Hydroxypropyl methylcellulose hpmc cellulose ether properties:
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.
Operationality: It can enhance the plasticity of mortar and improve the coating efficiency in construction projects.
Adhesivity: It can make mortar attach to base material better since the plasticity of mortar is enhanced.
Slip Resistance: It can prevent slipping problem between mortar and the base material in construction project as a result of its thickening effect.
Hydroxypropyl methylcellulose hpmc cellulose ether typical Applications:
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.
·Water retention ensures prolonged work time.
·Sag resistance: improved mortar bonding ability.
