CONCENTRATED ANTIFOAM AND DE-AERATING AGENT

AVCO-TEX CAN is a unique anti-foam and penetration accelerant with excellent de-foaming and de-aerating properties, which ensure high speed and even wetting of the treated textiles. It is an highly efficient, concentrated defoamer with long lasting defoaming effect. It can be used in all kind of aqueous processes such as printing, to increase the penetration of the printing paste, and in pretreatment, bleaching and dyeing processes to increase the even pick-up in high-speed continuous machines.

It is often impossible to work without any defoamer in the pretreatment or dyeing process, when using some special foaming auxiliaries, or when the textiles contains foaming oils and lubricants. The use of AVCO-TEX CAN ensures foam free pretreatment or dyeing processes.

PROPERTIES & USES:

1. Excellent and long lasting antifoaming effect in many application fields.

2. Suitable for all types of pretreatment, bleaching, dyeing and finishing procedures, in continuous and batch machines. AVCO-TEX CAN is stable to HT conditions.

3. Promotes fast and even liquor pick up through the whole cross section of the fibres.

4. Excellent penetrating agent for aqueous printing pastes of pigments, reactive and acid dyestuffs.

5. AVCO-TEX CAN is not foaming at all, and suppresses the foam of other surfactants.

6. Can be used in high alkaline or mild acid liquors.

7. No spot formation even at elevated temperatures, easy to wash-off.

8. Durable action through all the dyeing or the bleaching cycle.

9. Concentrated de-aerating and antifoaming agent, Very efficient even at low dosages.

APPLICATION:

AVCO-TEX CAN can be dosed as it is or pre-diluted, with cold water.

1. Defoaming

use: 0.2 – 0.5 g/l
