KDR-20 is a protein based high efficiency gypsum retarder, researched by our own company independently. It has super retarding effect with smaller dosage, which can adjust the gypsum products' setting time freely by customers' various needs. It is a white powder with good fluidity, which can be mixed and dispersed well with gypsum, either by spiral mixing or grinding. Using this product, the working time of the gypsum can be prolonged for an hour or hours on demands.

Our KDR-20 model is equivalent to PLAST RETARD PE. It is mainly used in gypsum building materials such as gypsum-based plastering, bonding gypsum, gypsum wall putty, gypsum-based self-leveling mortar, and gypsum products.
