1.Description
SJZ-12 is a new type of protein based high efficiency gypsum retarder. 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.
SJZ-12 is special designed for desulphurization gypsum. It can be apply to plaster gypsum, plaster adhesives, plaster precast, gypsum filler, gypsum mode, and gypsum decorating coating.
SJZ-12 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 SMF super plasticizer together.

( The setting time will be prolonged by dosage increase.but due to setting
retarding effect maybe different by different gypsum, it should make testing
design for dosage before production application. ) |
