Hydroxypropyl Methyl Cellulose (HPMC) is a derivative of methyl cellulose.HPMC is a non-ionic cellulose ether made from natural renewable polymers such as cotton or wood pulp. It is an odorless, tasteless, non-toxic white powder that dissolves in cold water to form a clear viscous solution.
Water retention
Enhance the water retention, improve the phenomena of poor hardening and cracking caused by too fast drying and hydration of cement and gypsum building materials.
Improve workability
Increase the plasticity of mortar, improve the constructability of industrial painting, and improve the working efficiency;
Adhesion
Due to the increase of mortar plasticity, it can better bond with the substrate and be bonded;
Anti-slip properties
Due to its thickening effect, it can prevent the mortar and the bonded object from slipping during the construction process.
What are the main application areas of HPMC in the construction industry?
HPMC is mainly used in tile adhesive, wall putty, cement-based mortar, gypsum-based mortar, self-leveling flooring, exterior wall insulation mortar, etc.
Can HPMC be mixed with other additives in construction materials?
Yes, HPMC can be mixed with a variety of additives such as re-dispersible polymer powders, cellulose ethers and defoamers, depending on the specific application requirements.
How to use HPMC and what are the precautions?
The main method of use is to add HPMC into water slowly, dissolve it while stirring, and be careful not to add too much at one time to avoid lumping.
What are the storage conditions of HPMC?
HPMC should be stored in a dry, cool and well-ventilated environment, avoiding direct sunlight and high temperature.
What are the precautions for transportation of HPMC?
When transporting HPMC, we should make sure that the package is intact and undamaged, avoid moisture and heat, and do not mix with toxic and dangerous goods.
