HPMC is a non-ionic cellulose ether made 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.
HPMC has good water retention, convenient construction, and wide viscosity range to meet various needs.
The good performance of hydroxypropyl methylcellulose (HPMC) can significantly improve the performance of mortar, pumping performance and spraying performance. It is an important additive in mortar.
HPMC has excellent water retention and is widely used in various mortars, including masonry mortars, plastering mortars and floor leveling mortars, to improve the bleeding properties of mortars.
HPMC has a significant thickening effect, improves the construction performance and workability of mortar, changes the fluidity of the product, achieves the expected appearance effect, and improves the fullness and volume of mortar.
HPMC can improve the adhesion and operability of mortar, overcome common problems such as shelling and hollowing of ordinary mortar, reduce blanking, save materials and reduce costs.
Hydroxypropyl methylcellulose has a certain retarding effect, which can ensure the use time of mortar and improve the plasticity and construction effect of mortar.
Hydroxypropyl methylcellulose can introduce a proper amount of air bubbles, which can greatly improve the frost resistance and durability of the mortar.
Cellulose ethers combine physical and chemical functions to retain moisture and thicken. Substances that cause micro-expansion properties are produced during the hydration process, so that the mortar has a certain micro-expansion property and prevent the mortar from hydrating later. Shrinkage-induced cracks increase the lifespan of the building.
