- HPMC's utility in construction lies mainly in its ability to improve the workability of concrete and mortar. It acts as a superplasticizer, enhancing the flow properties without reducing the strength of the mixture. This allows for easier handling and placement, reducing the need for excessive water, which can weaken the final product. Moreover, HPMC's water retention property ensures that the mix remains moist during setting, preventing early dehydration and cracks, thus improving the durability and stability of structures.
- Furthermore, HPMC is used in the paint and coatings industry due to its excellent film-forming, adhesion, and water retention properties. It improves the flow and leveling of paints, leading to a smoother finish, and aids in the prevention of sagging and brush marks.
- At the molecular level, HPMC consists of a cellulose backbone with hydroxypropyl and methoxy groups attached as substituents. These substitutions disrupt the hydrogen bonding between cellulose chains, reducing the crystallinity of the material. As a result, HPMC does not form the strong interchain associations typical of native cellulose, making it more susceptible to solvation by water molecules.
