Products Description


Protein Gypsum Retarder
KDR-18
KDR-18 is a new type of protein based high
efficiency gypsum retarder, researched by 
our own company 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.
