High-quality construction chemical additives are the core guarantee for improving dry mortar construction performance and long-term durability. As the market demands higher standards for tile adhesive, wall putty, gypsum plaster and thermal insulation mortar, ordinary low-performance additives can no longer meet the requirements of high-end building material production. Unstable viscosity, insufficient water retention and poor anti-sag performance will easily cause construction defects such as mortar sagging, surface cracking and hollow bonding.
