2. Molecular Weight HPMC is available in various molecular weights, ranging from low to high. Lower molecular weight grades dissolve more quickly and produce less viscous solutions, while higher molecular weight grades yield thicker gels and more viscous solutions. This versatility allows HPMC to be utilized in various formulations, depending on the desired consistency and functionality.
In the realm of construction, propyl methyl cellulose is widely employed as an additive in cement-based products
. When mixed with water, PMC forms a viscous solution that enhances the workability and adhesion of mortar and plaster. This property is particularly beneficial in tile adhesives, where it helps to improve the ease of application and ensures a strong bond between tiles and substrates. Moreover, PMC contributes to the water retention of the mixtures, allowing for longer working times, which is crucial in construction applications.
