Hydroxypropylmethylcellulose is a nonionic water-soluble cellulose ether that provides a variety of functional properties when dissolved in water. It can be used as a thickener, binder, surfactant, protective colloid, suspending agent and water retention agent.
HPMC powder is a semi synthetic, inactive, and viscoelastic polymer, belonging to one of the non ionic cellulose mixed ethers. HPMC is an important cellulose ether with a wide range of uses and functions. In the solid state, it is a pure white slightly yellow powder product, with a white or slightly yellow fibrous or granular appearance. It has good stability and is incompatible with strong oxidants. The product is flammable. There are strict requirements for production, transportation, and storage.
Functions
Water retention
Enhance water retention, improve the phenomenon of poor hardening and cracking caused by too fast drying and hydration of cement and gypsum building materials.
Improvement of ease of use
Increase the plasticity of mortar, improve the workability of industrial coatings, and improve work efficiency;
Bonding
Due to the increase of mortar plasticity, it can better bond with the substrate and be bonded;
Anti-slip
Due to its thickening effect, it can prevent the occurrence of slipping of mortar and bonded objects during the construction process.
