Hydroxypropyl methyl cellulose is a non-ionic cellulose ether prepared from pure cotton through a series of chemical treatments. Mainly used in the construction industry: waterproof putty powder, putty paste, steel putty, paint glue, masonry mortar, dry powder insulation mortar and other dry building materials.
Hydroxypropyl methylcellulose (HPMC) has excellent water retention and is widely used in various mortars, including masonry mortar, plastering mortar and floor leveling mortar, to improve the bleeding of mortar.
Hydroxypropyl methylcellulose (HPMC) has a significant thickening effect, improves the construction performance and workability of the mortar, changes the fluidity of the product, achieves the expected appearance effect, and improves the fullness and volume of the mortar .
Hydroxypropyl methylcellulose (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 costs.
Cellulose ethers combine physical and chemical functions to maintain water and thicken. During the hydration process, substances that cause micro-expansion properties are produced, so that the mortar has a certain degree of micro-expansion performance and prevents the mortar from hydration in the later stage. The cracks caused by shrinkage increase the service life of the building.
