Gypsum Retarders

Product Description

Gypsum retarder is a high performance and environmentally friendly protein-based retarder that can slow down the setting time of gypsum plaster. Even applied with small amounts, our high-efficiency gypsum retarder produces excellent retardation effects with minimal loss of gypsum strength. With good adaptability to various gypsums, the addition of our products can help adjust the setting time to meet the specific product and job needs and allow for proper application and finishing. When employed together with our water-reducing admixture, it can help adjust the setting time and gypsum plaster consistency in a more effective way.

Gypsum retarder is mainly used to slow down the curing process of gypsum by inhibiting the crystal growth and nucleation of gypsum. Commonly used gypsum retarders are organic acid salts, phosphates, sulfates, etc. These compounds can combine with Ca2+ ions in gypsum to hinder the growth and formation of gypsum crystals, thus slowing down the curing process of gypsum.

If you need to use gypsum retarder, please be sure to follow the recommendations and instructions of gypsum based supplier to ensure the quality and safety of the product.
