The light transmittance of hydroxypropyl methyl cellulose is mainly affected by the following points:

The important role of water-soluble hydroxypropyl methyl cellulose ether in mortar is mainly in three aspects, one is excellent water retention capacity, the other is the effect on the consistency and thixotropy of mortar, and the third is the interaction with cement.

Hydroxypropyl Methyl Cellulose(HPMC) for wall putty.The wall putty is also named skim coat ,it is a decorative and functional trowelling plaster material for interior or external wall building . the function is to remove uneven defects on the surface of the base materials of wall, and eliminate the stress between different coating layers.

Hydroxypropyl methylcellulose(HPMC) is a natural polymer cellulose material as raw material, made after a series of chemmical processing of non-ionic cellulose ether. A wide range in the following industry applications:

The light transmittance of hydroxypropyl methyl cellulose is mainly affected by the following points:

HPMC manufacturer-Hydroxypropyl Methyl Cellulose Dissolution Method

As for the particle size, the finer the particle, the better the water retention. After large particles of cellulose ether are touched with water, the surface will immediately dissolve to form a gel, which wraps the material to prevent the continuous entry of water molecules.

The greater the viscosity of hydroxypropyl methyl cellulose, the better the water retention. Viscosity is an important parameter of HPMC performance. At present, different HPMC manufacturers use different methods and instruments to measure the viscosity of HPMC. The main methods include HaakeRotovisko, Hoppler, Ubbelohde and Brookfield.

Water retention from hydroxypropyl methyl cellulose is one of the important properties of hydroxypropyl methyl cellulose. Factors such as air temperature, temperature and wind speed can affect the evaporation rate of moisture in cement mortar and gypsum based commodities.
