HPMC hydroxypropyl methylcellulose 20 questions (1) Industrial grade hydroxypropyl methylcellulose for mortar (referred to herein as pure cellulose, excluding modified products) is distinguished by viscosity. Generally used are the following grades (unit is viscosity) Low viscosity: 400 is mainly use for self-leveling mortar, but it is generally import. Reason: low viscosity, although the water retention […]
Some common problems in cellulose application(1)
Some common problems in cellulose application(1) 1.What is the appropriate viscosity of HPMC? Putty powder is generally 100,000. The mortar requires higher requirements. It needs 150,000 to be used. HPMC most important function is to keep water, followed by thickening. In Putty powder, as long as the water retention is good and the viscosity is […]
