Liquid, environmental friendly reducing agent
BIOREDUKT TOP-NS Overview
- BIOREDUKT TOP-NS is a liquid, direct dosable reducing agent with dispersing properties for the reductive cleaning of disperse dyeings and printings on Polyester.
- BIOREDUKT TOP-NS does not contain sulphur or nitrogen and is therefore especially environmental friendly.
- BIOREDUKT TOP-NS has besides its high reducing also excellent dispersing power on disperse dyestuffs, whereby highest fastness levels on PES and PES/Ly articles are achievable.
- BIOREDUKT TOP-NS does not impair the light fastness.
- BIOREDUKT TOP-NS can be also dosed into the alkaline switched cooling bath, resulting in significant savings in water, energy and time.
