Building Construction Chemicals Hydroxypropyl Methyl Cellulos

Brief introduction:

Hydroxypropyl Methyl Cellulose (HPMC) another name is Hypromellose, it is is a natural polymfer cellulose as raw material, made of a series of chemical processing and non-ionic cellulose ether. It is white powder with good water solubility. hpmc have many properties such as thickening, adhesion, dispersing, emulsifying, film, suspended, adsorption, gel, and protective colloid properties of surface activity and maintains moisture function properties .Hydroxypropyl Methyl Cellulose are widely used in construction materials,building materials, coatings industry, synthetic resin, ceramic industry, textile, agriculture, daily chemical and other industries.
Hydroxypropyl Methyl Cellulose (HPMC) helps building materials apply more easily and perform better. They provide water retention and cohesiveness to mixtures. With special modification, it can be used to control thickening, water demand, workability, sag resistance, strength and other important properties of the final product.It is widely used as thickener, adhesive, water preserving agent, film-foaming agent in building materials, industrial coatings, synthetic resin, ceramic industry, medicine, food, textile, agricultural, cosmetic and other industries.

The Hydroxypropyl Methyl Cellulose (HPMC) Application in constructions:
External wall insulation system (EIFS)
1,Bond strength: Hydroxypropyl Methyl Cellulose can provide the greatest degree of high adhesive bond strength of mortar.
2,Performance: The mortar added HPMC has the right consistency, non-sagging. When using, the mortar is easy to work continuously, uninterrupted.
3,Water retention: HPMC cellulose can wet the wall insulation easily, easy to paste, and also make other additional materials reach the best affects.
4,Absorbent: HPMC can minimize the air-entraining volume, lower water absorption of mortar.
Interior and exterior wall interface agent
1,Easy to mix, without of agglomeration: Hydroxypropyl Methyl Cellulose (HPMC) can significantly reduce the friction in the dry powder during the process of mixing with water, which makes it easy to mix and save the blending time.
2,Water retention: HPMC cellulose can significantly reduce the moisture absorption by the wall. Good water retention can ensure the cement compound with a longer time, also can ensure that workers are able to carry out many times of scraping for the putty on the wall.
3,Good working performance stability: even in high temperature environment, it can still maintain good water retention. it is suitable for construction in the summer or hot areas.
4,Increased water demand: it can significantly improve the water demand of the putty materials. On the one hand, it improves the operational time after putty put on the wall, on the other hand, it can increase the coating are of the putty, which can make the formula more economical.
Tile adhesive
1,Water retention: Hydroxypropyl Methyl Cellulose (HPMC) can reduce the moisture absorbed by the substrate and the tile, retain the moisture in the adhesives as much as possible, making mortar still have adhesion after coating for a long time. Significantly extend open time and makes bigger coating area for the worker each time, and improve the efficiency. 
2,Improve bond strength, improve anti-slip performance: it can ensure non sagging of the tiles during working, especially for heavy tile, marble and other stone materials. 
3,Work performance: The lubricity of HPMC can increase the workability of the mortar significantly, which makes the mortar easy to coating and improve efficiency.
4,Improve mortar wetting property: Hydroxypropyl Methyl Cellulose give mortar consistency, enhance the wetting ability of mortar and substrate, increase the binding strength of wet mortar, especially for the recipe with high water cement ration; 
Crack Filler
1,Workability: provide the right viscosity, plasticity, and easy to work;
2,Water retention: can make the slurry fully hydrated, extending the working time and avoid cracking.
3,Anti-hanging: HPMC cellulose can make a strong adhesion on the surface for the slurry and not sag;
Self-leveling mortar
1,Prevent bleeding: HPMC cellulose can play a very good role to prevent the slurry sedimentation, bleeding.
2,Maintain liquidity, and improve retention: low viscosity HPMC will not affect the slurry flow effect and easy to work. While possesses certain water retention, makes the good surface effect after self-levelling and avoid cracks.
