Additive "SVV-500 gypsum Converter" (TU 08.11.20-013-53855500-2017) is a fine powder of light gray color containing a gypsum hardening activator, a hyperplasticizer and a defoamer. The additive is designed to dramatically improve the basic properties of gypsum binders:
- increases strength by 8-10 times;
— increases ductility, making the mixture-cast;
- - improves surface quality by removing vapors;
— slightly slows down the setting time of the water-gypsum mixture.
