Usage | Our HPMC is mainly used in the construction field. In building construction, it is mainly used for external wall thermal insulation system, thermal insulation mortar, decoration mortar, masonry mortar and self-leveling mortar etc.. It is used as thickener, stabilizer, emulsifier, excipient, water retaining agent, film-forming agent etc. During the decorative construction, it is mainly used for building walls, stuccoing, caulking and other mechanized construction It can be used to paste ceramic tile, marble and plastic decoration, which isof high adhesive strength and can also reducethe amount of cement. When used as thickener in coatings industry,it can make thecoating light and delicate without taking off of powder and improve leveling performances etc | |||
