One of the most prominent features of Cellosize HEC is its thickening and binding capabilities. In the construction industry, for instance, it is widely utilized in the formulation of adhesives, sealants, and mortars. The addition of Cellosize HEC enhances the viscosity of these compositions, improving their workability and application aside from preventing the separation of components in aqueous mixtures. This thickening property is particularly advantageous in tile adhesives, where it aids in maintaining a consistent texture and ensures that the adhesive remains effective over time.
3. Fire and Stability Although HPMC is not classified as flammable, the MSDS suggests keeping it away from open flames or high temperatures. In case of fire, carbon dioxide or dry chemical extinguishers can be used. It's important to store HPMC in a cool, dry environment to maintain its stability and effectiveness.
This redispersible powder showcases several advantageous properties. Its excellent film-forming ability enhances the binding strength of mixtures, while its flexibility allows it to accommodate structural movements without cracking. Additionally, the water resistance offered by VAE makes it ideal for exterior applications. The outstanding thermal stability helps maintain the integrity of the final product even under varying conditions.
In construction, HPMC enhances the workability of cement and mortar mixtures, providing improved adhesion and water retention properties, which are essential for the durability of structures.
