AVCOTEX F5 is an unique penetration accelerant with excellent de-foaming and de-aerating properties.
AVCOTEX F5 can be used in all kind of aqueous processes such as printing to increase penetration of the printing paste, and in bleaching and dyeing recipes to increase the even pick-up in high-speed continuous machines.

PROPERTIES & USES:
- Excellent penetrant for aqueous printing pastes of pigments, reactive and acid
dyestuffs.
- Suitable for all types of pretreatment, bleaching, dyeing and finishing
procedures, in continuous and batch machines.
- Promotes fast and even liquor pick up through the whole cross section of the
fibres.
- AVCOTEX F5 is non foaming at all, and suppresses foam of other surfactants.
- Can be used in high alkaline or mild acid liquors.
- No spot formation even at elevated temperatures.
- Durable action through all the dyeing or bleaching cycle.
APPLICATION:
-
To increase penetration of aqueous printing paste into fabrics.
use:5 – 15 g/kg
-
High speed wetting, improving penetration on treatment liquors with no foam.
use: 0.3 – 1 g/l
-
To increase pick-up of bleaching.
use: 0.5 – 2 g/l
-
De-aerating and wetting of densely packed fibre and yarns
use: 0.5 – 1.5 g/l
REMARKS
Before using AVCOTEX F-5 in dyeing liquors check compatibility with all ingredients of the
dyeing recipe.
