Hydroxypropyl MethylCellulose (HPMC) are widely used in construction, pharmaceutical,food, cosmetic, detergent, paints, as thickener, emulsifier, film-former, binder, dispersing agent, protective colloids.
HPMC-Hydroxypropyl Methyl Cellulose and Methyl Hydroxyethyl Cellulose and non-ionic cellulose ether made by natural high polymer cellulose as raw material and series of chemical processing. They are odorless, tasteless and non-toxic white powder, which can be dissolved in cold water to form a transparent viscous solution. Processing thickening, binding, dispersing, emulsifying, film, coating, suspending, absorbing, gelling, surface activity, water maintaining and protective colloid properties
Hydroxypropyl methyl cellulose HPMC is a non-ionic water-soluble cellulose mixed ether. The appearance is white to light yellow powder or granules, tasteless, odorless, non-toxic, it is a chemically stable product, soluble in water, forming a smooth and transparent viscous solution. The production process of HPMC is mainly to form polysaccharide ether products after etherification of cotton fibers. It has no charge itself, does not react with charged ions in cementitious materials, and has stable performance. cheap price. Widely used in dry powder mortar. In mortar, the thickening of the mortar can have a certain wet viscosity, which helps to maintain the amount of free water in the mortar, so that the gel material has more time to hydrate after the mortar is used.

The quality of HPMC used in the construction of mortar is relatively good. Adding a certain amount of HPMC will achieve a very good effect. It can produce high water retention in mortar, and the thickening construction can be greatly improved.
At the same time, it can increase the tensile strength of the mortar and improve the construction efficiency. Hydroxypropyl methylcellulose HPMC in waterproof putty also has a very good water retention effect, which can improve the good adhesion and lubricity of HPMC. At the same time, it also enhances the adhesion of putty and reduces the occurrence of sagging, making the construction effect relatively stable.
Hydroxypropyl methylcellulose increases water retention. Adding it to plaster can improve the water retention and lubricity of gypsum, while also producing a good delay effect.
