Hydroxypropyl methylcellulose is a nonionic cellulose ether prepared by a series of chemical processing using pure cotton as a raw material. Mainly used in the construction industry: water-resistant putty powder, putty paste, steel putty, paint glue and masonry mortar, dry powder insulation mortar and other dry powder building materials.

Hydroxypropyl methylcellulose(HPMC) has good water retention effect, easy construction, and a wide variety of viscosities to meet a variety of needs.

The good performance of hydroxypropyl methyl cellulose (HPMC) can significantly improve the mortar performance, pumping and spraying performance, etc. It is an important additive in mortar.

  1. Hydroxypropyl methyl cellulose (HPMC) has excellent water retention performance and is widely used in various mortars, including masonry mortar, plastering mortar and ground leveling mortar to improve the bleeding of mortar.
  2. Hydroxypropyl methyl cellulose (HPMC) has significant thickening effect, improves the construction performance and workability of the mortar, changes the fluidity of the product, achieves the desired appearance effect, and improves the fullness and volume of the mortar.
  3. Hydroxypropyl methylcellulos(HPMC) can improve the cohesiveness and operability of mortar, overcome common problems such as shelling and hollowing of ordinary mortar, reduce blanking, save materials and reduce cost.
  4. Hydroxypropyl methylcellulose(HPMC) has a certain retarding effect, which can ensure the operable time of the mortar and improve the plasticity and construction effect of the mortar.
  5. Hydroxypropyl methylcellulose (HPMC) can introduce appropriate amount of air bubbles, which can greatly improve the frost resistance of the mortar and improve the durability of the mortar.
  6. Cellulose ether combines physical and chemical functions to maintain water and thicken. In the process of hydration, it can produce substances that cause micro-expansion properties, thus making the mortar have a certain micro-expansion property and preventing the mortar from hydrating in the later stage. Cracking caused by shrinkage increases the service life of the building.
