AVCO-DISPERSANT NS

Download File TDS

A low-foaming dispersing agent used in dyeing of polyester, polyester blends and acetates with disperse dyestuffs. It is also used as dispersing agent in Vat dyeing and cationic stripping off processes.

Properties & uses:

As a protective colloid and dispersing agent, particularly beneficial in dyeing with vat & disperse dyes where high concentrations of dye or highly concentrated powder or paste grades are being used
The excess concentrations of AVCO-DISPERSANT NS have no adverse affect
Not recommended for use with optical brightener
Improves dye-bath stability in circulating liquor dyeing machine
For the shock oxidation of vat dyes 2-3g/lít AVCO-DISPERSANT NS are added to the oxidation bath. This prevents any oxidized vat dye still left in the bath from filtering out and impairing the rub fastness of the dyed material
Use for stripping off cationic fixing agent

Ionicity:

Nonionic/ Anionic
