High Efficient Gypsum Retarder

■ Description

MNC-GR is a new type of high efficient 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 according to customers’ various needs. It helps gypsum and plaster products to have few strength loss rate after gypsum is hardened.

MNC-GR is a white powder agent with good fluidity, which can be mixed and dispersed well with gypsum, either by spiral mixing or grinding. With this admixture, the operating time of the gypsum can be prolonged for an hour or several hours on demands. It has easy construction, more efficiency, and lower cost. It helps more to adjust the setting time and consistency of gypsum paste optionally combined with our MUHU superplasticizer SMF together.
