KimaCell® MHEC MH150M methyl hydroxyethyl cellulose is the most commonly used admixture for construction wall putty, and it has good water retention performance, prolongs working time, improves construction performance, and improves work efficiency. The interior wall environmental protection putty with diatomite as the main functional filler, systematically studied the effects of different viscosities of HPMC and the amount of the putty on the putty's water resistance, bonding strength, initial drying crack resistance, sanding, construction and surface drying time. The bond strength of wall putty increases first and then decreases with the increase of MHEC dosage.

KimaCell® MHEC MH150MS methyl hydroxyethyl cellulose is soluble in water and some organic solvents. It can be dissolved in cold water. Its maximum concentration only depends on the viscosity. The solubility changes with the viscosity. The lower the viscosity, the greater the solubility. MHEC products are non-ionic cellulose ethers and are not polyelectrolytes, so they are relatively stable in aqueous solutions when metal salts or organic electrolytes exist, but excessive addition of electrolytes can cause gelation and precipitation.
Due to the surface active function of the aqueous solution, MHEC can be used as a colloidal protective agent, emulsifier and dispersant.
When the aqueous solution of MHEC products is heated to a certain temperature, it becomes opaque, gels, and precipitates, but when it is continuously cooled, it returns to the original solution state, and the temperature at which such gels and precipitates occur mainly depends on their lubrication. agent, suspending agent, protective colloid, emulsifier, etc.is
