Bioredukt TOP
Liquid, environmental friendly reducing agent

 


BIOREDUKT TOP – Overview

  • BIOREDUKT TOP is a liquid, directly dosable reducing agent with dispersing properties for the reductive afterclearing of disperse dyeings on polyester

  • BIOREDUKT TOP contains no reducing agent based on sulphur or nitrogen and therefore it is outstanding environmental friendly

  • BIOREDUKT TOP has in addition to the strong reduction capacity also an excellent dispersing effect for disperse dyestuffs which leads to highest fastness levels for PES and PES/EL

  • BIOREDUKT TOP does not influence the light fastness

  • BIOREDUKT TOP can be dosed in the cooling dyebath which results in water , time and energy savings



BIOREDUKT TOP – advantages compared to powder products

Product properties
Advantage
hydrogen – and sulphur free
environmental friendly, no contamination of waste water by sulphites/sulphates (therefore no damage of concrete sewage pipes, meets conditions of sewage limits)
strong reduction agent in combination with a high dispersing effect
effective dispersing and removing of unfixed dyestuff from the fibre, therefore, highest fastness possible
liquid, easy dosable
easy handling, no pre-dissolving necessary
no dust
less air contaimination
low foaming
suitable for jet dyeing machines
odourless
produces no odour by application with open equipment and machines
directly dosable in the cooling bath
simple single bath method, cost and time saving
