Hydroxypropyl methyl cellulose, also known as hydroxypropyl methyl cellulose, fiber bundle hydroxypropyl methyl ether, is the selection of highly pure cotton fiber as raw material under alkaline conditions by special
etherification and preparation.It has the characteristics of thickening ability, salt resistance, low ash content, PH stability, water retention, dimensional stability, excellent film forming, and extensive mildew resistance,
dispersibility and adhesion.
Construction industry
1.Cement mortar
2.Ceramic tile cement
3.Asbestos and other refractory coating: as a suspension agent, fluidity improver, but also improve the adhesion of the substrate
4.Gypsum coagulant slurry: improve water retention and workability, improve adhesion to the substrate
5.Joint cement: added to the ground joint cement for gypsum board to improve the fluidity and water retention
