General

The setting time of building gypsum after mixing with water is mostly 6-18 minutes(without gypsum retarder). The retarder reduces the solubility of hemihydrate gypsum and slows down the dissolution rate of hemihydrate gypsum. The retarding ions are adsorbed on the surface of dihydrate gypsum crystals and combine these ions into the crystal to form a complex, it limits the diffusion of the example to the vicinity of the dihydrate gypsum crystal, thereby delaying the setting time of  gypsum plaster.

Specifications

Characteristics 

The retarder is compatible with hydroxypropyl methylcellulose, starch ether, latex powder, superplasticizer, etc., it has good dispersibility, water solubility,  and controllable gel time under control meets construction requirements

Applications

It can be used for natural gypsum, desulfurized gypsum, phosphogypsum, and fluoro gypsum. This retarder is suitable for plaster products such as plastering plaster, machine-sprayed plaster, gypsum-based self-leveling, gypsum putty, bonding plaster, and prefabricated gypsum components.

Shelf life: 12 months

Packaging:  25kg/bag lined with PE film.
