As a common building material, hydroxypropyl methylcellulose HPMC is more important in the construction industry. What are the main functions of hydroxypropyl methylcellulose?
1. Masonry mortar
Enhanced adhesion to the masonry surface and can enhance water retention, thereby increasing the strength of the mortar, improving lubricity and plasticity to help construction performance, saving time and improving cost-effectiveness while being easy to apply.
2. Sheet caulking agent
Because hydroxypropyl methylcellulose HPMC has excellent water retention, it can prolong the cooling time, and its high lubricity makes the application smoother. Effectively improve the surface quality, provide a smooth and uniform texture, and make the bonding surface more firm.
3. Cement-based gypsum
Improves uniformity, makes plaster easier to apply, enhances flow and pumpability, and improves work efficiency. It has high water retention and prolongs the working time of the mortar. In addition, it can control the penetration of air, thereby eliminating micro-cracks in the coating and forming a smooth surface.
4. Gypsum products
It can prolong the working time of the mortar and produce higher mechanical strength during the setting process. By controlling the uniformity of the mortar, the quality of the surface coating formed is better.
5. Water-based paint and paint remover
Extends shelf life by preventing solid precipitation, has excellent compatibility and high biostability. It dissolves quickly and doesn’t clump together, helping to simplify the mixing process. Produces good flow characteristics, including low spatter and good leveling, ensures an excellent surface finish and prevents paint sagging. Enhance the viscosity of water-based paint remover and organic solvent paint remover, so that the paint remover will not flow out from the surface of the workpiece.
6. Tile glue
Dry blends are easy to mix and do not clump, saving work time as application is faster and more efficient, improving processability and reducing costs. Provides excellent adhesion by extending the cooling time and increasing tiling efficiency.
7. Self-leveling ground material
Provides viscosity and can be used as an anti-settling additive to help improve the efficiency of laying floors. Controlling water retention can greatly reduce cracks and shrinkage.
8. Production of formed concrete slabs
Enhances the processing properties of extruded products, has high bonding strength and lubricity, and improves the wet strength and adhesion of extruded sheets.
