Featured Applications
Gypsum Plaster
Gypsum-Based Self-Leveling Compound
LANDU NOVASTAR Gypsum retarder slows down the hydration of gypsum in self-leveling compounds. This delay allows the slurry to flow freely under gravity and achieve the required spreadability. It also provides a longer opening time, allowing workers to mix, pour, and spread the self-leveling compound evenly before it begins to set.
Gypsum Board
LANDU NOVASTAR gypsum retarder, used at dosages typically ranging from 0.01& to 2.0% by weight of gypsum, controls and adjusts the setting time for extended workability. This control is vital for gypsum board production, where the gypsum slurry is poured onto a moving conveyor belt with paper. The retarder ensures that the slurry remains fluid long enough to bond with paper layers and be handled without cracking.

Frequently Asked Questions
– You may add the gypsum retarder of the proper amount directly to the water and stir it to achieve a uniform consistency.
– The setting process can be affected by the temperature. You may contact LANDU NOVASTAR to request a dedicated formulation with proper dosage measured based on your local environment.
– Remember to clean mixing containers and tools after use, as gypsum mixtures can harden quickly and become difficult to remove.
