HPMC can be used as a dispersant in construction treatments
HPMC, as a dispersant, thickener, and adhesive in construction processing, is mainly used for molding cement mortar and gypsum products. It is used in cement mortar to increase its adhesiveness, reduce flocculation, improve viscosity and shrinkage, and maintain moisture retention. It reduces moisture loss on the concrete surface, enhances strength, and prevents cracking and weathering caused by water-soluble salts; HPMC has thixotropy, allowing the preparation of low-flow, one-time thick gypsum coatings on vertical walls; HPMC can improve adhesion and structural performance, suitable for preparing easily flowable spray mortar for thin-layer coatings.
