independently . It has super retarding effect with smaller dosage. It can adjust the gypsum products' setting time freely by customers’ various needs. It helps gypsum and plaster products to have few strength loss rate after
gypsum hardened.
KDR-18 is a white powder agent with good fluidity, which can be mixed and dispersed well with gypsum,either
by spiral mixing or grinding. Using this agent, the working time of the gypsum can be prolonged for an hour or
hours on demands. It helps to easy work, more efficiency , and lower cost. It helps more to adjust the setting
time and density of gypsum paste optionally combined with our KPS-500 superplasticizer together.
