HPMC 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.
Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether made from pure refined cotton, etherified under alkaline conditions with propylene oxide and chloromethane as etherizers, it is an odorless, non-toxic white or off-white powder, dissolved in cold water, dissolved into a transparent or slightly turbid colloidal viscous solution, with a degree of substitution of 1.2-2.0 in general, and its performance varies depending on the ratio of the methoxyl content and the hydroxypropyl content. Its performance is affected by the proportion of methoxy content and hydroxypropyl content and there are differences. Main components: cotton, chloromethane, propylene oxide, liquid alkali.
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.
