| Usage: | "Application of Hydroxypropyl Methyl Cellulose in Building Materials Masonry mortar plastering mortar High water retention can fully hydrate the cement. Significantly increased bond strength. At the same time, the tensile and shear strength can be appropriately improved. Greatly improve the construction effect and improve work efficiency. Water resistant putty The main function of cellulose ether in putty is to retain water, bond and lubricate, to avoid cracks or powder removal caused by excessive water loss, and at the same time increase the adhesion of putty, reduce the sagging phenomenon during construction, and make the construction smoother. Save effort. Interface agent It is mainly used as a thickener, which can improve the tensile strength and shear strength, improve the surface coating, enhance the adhesion and bond strength. " | |
