Gypsum retarder is mainly used to adjust the setting time of gypsum (especially gypsum-based materials) during the construction process. Its main components are usually some organic or inorganic retarders, which can slow down the hydration reaction of gypsum and prolong its setting time. This regulation is very important in building and decoration construction, especially for occasions that require longer working time, such as large-scale construction, complex mold pouring, etc.
Gypstar® is recommend for gypsum plaster, gypsum bonding compound, gypsum putty, gypsum precast,gypsum filler, gypsum modeling and gypsum based decorative coating.

1. Extend the setting time: delay the initial and final setting time of gypsum, improve construction efficiency, and avoid wasting materials.
2. Improve construction adaptability: stabilize the setting time of gypsum in high temperature or low humidity environment, and achieve smooth construction under various weather conditions.
3. Improve surface quality: extend the operation time, facilitate surface finishing, and obtain a smoother effect.
4. Reduce cracks and deformation: uniform setting and hardening, reduce cracks and deformation problems of gypsum products.
Packed in 25 kg multilayer paper sack with polyethylene intermediate layer and inner P.E. bag.It is recommended that it be kept sealed and away from moisture. Do not expose it to direct sunlight or near fire sources.
Gypsum binder is a bonding material mainly composed of building calcined gypsum.It is mainly used for bonding decorative gypsum products. Gypsum binder is more suitable to bonding gypsum product than cement based mortar.
Gypsum binder has the advantages of slight expansion, environmental protection, good adhesion, no cracking, and no hollowing,etc.
