Hydroxypropyl methyl cellulose ether (HPMC) is a nonionic composite ether. Thanks to the function of composite etherification groups, HPMC has excellent water solubility, can be dissolved in water in any proportion, and has high concentration and high viscosity. It is stable in a wide PH range, and will not be degraded even in the strong alkaline environment generated during cement hydration.

The aqueous solution of hydroxypropyl methyl fiber ether has the properties of adhesion, water retention, thickening and film formation, which can provide water retention and thickening in building mortar products and effectively improve the operability of cement, lime and gypsum-based mortars.

Cellulose ether materials with proper viscosity and dosage can provide excellent rheological properties and opening time for building mortar materials. So that the commercialization of high-performance building mortar materials is possible.。

Hydroxypropyl methyl cellulose ether has stable chemical properties and can be well compatible with other additives added to building mortar products. (such as redispersible latex powder, polyvinyl alcohol, starch ether, guar gum, etc.).）

The storage site of this product should be dry, ventilated, moisture-proof and sun-proof. In addition, in the process of transportation and loading and unloading, products with different batch numbers shall not be mixed, and the packaging shall not be thrown, squeezed and kept intact to avoid sun and rain.。
