Manufacturer Direct Sales of Putty Thickening Powder Coating Emulsifier Cement Thickener Hydroxypropyl Methyl Cellulose
As a nonionic cellulose mixed ether with excellent performance, HPMC has good dispersing, emulsifying, thickening, bonding, water retention and glue retention properties as other cellulose ethers (such as CMC, MC, HEC, MHEC, HEMC, HBMC). It is soluble in water, also soluble in ethanol and acetone below 70%. It can be widely used as thickener and adhesive.HPMC has thickening, dispersing and emulsifying film-forming properties, and is widely used in petrochemicals, building materials, ceramics, textiles, daily-use chemicals, synthetic resins, coatings and electronics and other industrial fields.
