Why is hydroxypropyl methyl cellulose added to mortar?

Hydroxypropyl methyl cellulose (HPMC) is a kind of non-ionic cellulose ether, which is made of natural polymer materials as raw materials and refined by a series of chemical processes. It has a good water retention effect, easy processing, wide viscosity range, and can meet different industrial needs. 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. High-quality HPMC can significantly improve the mortar construction performance, pumping, and spraying performance and is an important additive in mortar.

1. Matecel HPMC has excellent water retention and is widely used in various mortars, including masonry mortar, plastering mortar, and ground leveling mortar, to improve the water leakage of mortar.

2. Hydroxypropyl methyl cellulose ether has a significant thickening effect, improves the construction performance and workability of mortar, achieves the ideal appearance effect, and improves the fullness and volume of mortar.

3. Matecel HPMC can improve the adhesive property and operability of mortar, overcome the common defects of ordinary mortar, such as peeling and empty drums, reduce blanking, save materials and reduce costs.

4. Matecel HPMC has a certain retarding effect, can ensure the use of mortar time, and improve the plasticity of mortar and construction effect.

5. Hydroxypropyl methyl cellulose can introduce an appropriate amount of bubbles, and can greatly improve the frost resistance and durability of mortar.

6. Cellulose ether is a combination of the physical and chemical action of water-retaining thickening materials. It can produce micro-expansion material in the hydration process, so that the mortar has a specific micro-expansion performance, prevent the cracking caused by shrinkage in the later hydration process, and improve the service life of the building.

Matecel is one of the leading suppliers of high-performance cellulose ethers, including hydroxypropyl methyl cellulose (HPMC), hydroxyethyl methyl cellulose (MHEC), hydroxyethyl cellulose (HEC), carboxymethyl cellulose (CMC) from China. We provide the best quality products for the global market, with different degrees of substitution, and a wide range of viscosity, therefore suitable for different applications such as dry mixed mortar, paint, coatings, construction, chemical, etc.
