HPMC is the most important additive in tile adhesive, it delivers tile adhesive long open time, adjustment time, sag resistance and ensure cement hydration and improve the bond strength of tile adhesive.
HPMC provides water retention, workability and enough operation time for wall putty, it ensures smoothness and wettability of putty to base surface.
In the course of construction, mortar is an important building material, and its performance plays a crucial role in the quality and durability of the whole building project.
HPMC has function of water retention and thickening, it improves the adhesion strength and sag resistance of gypsum plaster and prevents plaster cracking, chalking and bulging caused by dry too fast and not enough hydration.
