At the same time, HPMC can also be used as a paste to replace natural materials, which can improve water retention and improve the bonding force with the substrate. As a plasticizer for latex coatings, it has a role in improving the performance and fluidity of coatings and putty powders. It has good effect on preventing cement-based or latex-based spraying only fillers from sinking and improving fluidity and spray pattern. It is used as an extrusion molding binder for cement-asbestos and other hydraulic substances to improve fluidity and obtain uniform molding. It is effective as a binder for sand walls due to its anti-enzyme and anti-bacterial effect. In other aspects, it can be used as an air bubble retainer for thin mortar and mortar and plasterer operators.
