What is the choice of HPMC viscosity when producing putty powder dry mortar?
Methyl cellulose MC and hydroxypropyl methyl cellulose (HPMC) have stable chemical properties. Mildew resistance and water retention are not affected by changes in pH. Viscosity can be used between 50,000 and 200,000, but in production, higher viscosity is better. Viscosity is inversely proportional to bond strength. The higher the viscosity, the lower the strength. Regarding […]
