HosechemTMGypsum retarder is a white powder with good fluidity, which can be mixed and dispersed well with gypsum, either by spiral mixing or grinding. It helps reduce the loss of strength after after gypsum gets hard, enhances work ability, improves efficiency and reduces costs.
Gypsum Retarder
DESCRIPTION
Gypsum retarder is a white powder with excellent fluidity that blends and disperses effectively with gypsum through either spiral mixing or grinding. It minimizes strength loss after gypsum hardens, enhances workability, improves efficiency, and reduces costs. Easily soluble in water, it is primarily used in gypsum-based building materials to delay the setting time, increase gypsum strength, and maintain its fluidity for an extended period. By significantly reducing gypsum waste and loss, gypsum retarders contribute to improved construction efficiency.
