The viscosity of aqueous solution of hydroxypropyl methyl cellulose is mainly affected by the degree of product polymerization, concentration of product in aqueous solution, shear rate and solution temperature. The viscosity of aqueous solution increases with the increase of product polymerization degree and concentration, and decreases with the increase of shear rate and solution temperature.Salt and safe insecticides can also be added to obtain better viscosity characteristics and application performance. Users should consider the actual situation and economy to choose hydroxypropyl methyl cellulose viscosity specifications and addition.
Hydroxypropyl methyl cellulose HPMC in the coating industry for thickening agent, can make the coating bright and delicate, do not deduster, improve leveling performance. It can be used to paint gypsum, paste gypsum, caulking gypsum, water – resistant putty to improve its water retention and paste strength. Also can be used in functional ceramics, metallurgy, seed coating agent, water-based ink, cosmetics, electronics, printing and dyeing, paper and other fields.
