Introduction
Construction grade Hydroxypropyl Methyl Cellulose (HPMC) as a new building material, It is non-ionic cellulose ether made by natural refined cotton as raw material and series of chemical processing.
It is odorless, tasteless and non-toxic white or slightly yellowish powder, which can be dissolved in water to form a transparent viscous solution.
It is used as thickener, emulsifier, film-former, binder, dispersing agent, protective colloids and water-retention agents in construction mortar.
We can offer the regular grade HPMC or the modified HPMC according to customer requirements.

Properties
● High water retention, making the moisture not easy to lose or be absorbed too quickly by the substrate.
● Thickening
● Anti-sagging, improved mortar bonding ability.
● Better workability, mortar can be applied easier and quicker.
● Longer open time, It can extend the hardening time of the mixture, make the raw materials fully hydrated, and improve the tensile strength and flexibility of the mixture.
● Reduce air entrancement and water uptake.
● Improved adhesion and sliding resistance: especially for heavy tiles.
