SG-32 Gypsum Retarder

◉ SG-32 can provide required setting time for gypsum mortar even at very low dosage, with minimal influence on the dry strength of the gypsum.

◉ SG-32 has a good compatibility with different gypsum such as natural gypsum, desulfurization gypsum, and other industrial by-product gypsum, with a pH range of 6.5-12.

◉ SG-32 performs better in a neutral or alkaline gypsum system.

◉ When matching with SUNBO® water reducer, defoamer and stabilizer, it can better adjust the recipe of gypsum mortar.
