Gypsum retarder for long setting time plaster

Product Description

Gypsum Retarder is a protein retarder developed for gypsum-based products and is widely used to adjust the setting time of various gypsum. In the mixture of gypsum and water, GR-70M as a retarder can reduce the growth rate of hydrated crystals. Its activity is reflected in the correlation between the setting time and the addition amount, and good performance can be obtained even at a low addition amount. GR-70M can be used alone in gypsum formulations, but can also be used with citric acid and tartaric acid to obtain delayed hardening and suitable consistency.
