The role and classification of hydroxypropyl methylcellulose
Low viscosity: 400 is mainly used for self-leveling mortar, but generally imported. Reason: The viscosity is low, although the water retention is poor, but the leveling is good, and the mortar density is high. Medium and low viscosity: 20000-40000 is mainly used for tile adhesive, caulking agent,...Read more -
