AVCO-ANTIFOAM NS-300

CONCENTRATED NON-SILICONE ANTIFOAM

AVCO-ANTIFOAM NS-300 is a very efficient antifoam and defoaming agent designed for aqueous systems.
The product is a non-silicone type, and can be used in high temperature aqueous systems, with no problems of oily stains in all types of preparation dyeing and finishing procedures.

SPECIFICATION:

Appearance Slightly viscous, opaque, cream colour liquid.
Chemical nature Emulsifiable hydrocarbon with special additives.
Compatibility Stable in aqueous processes used in textile preparation. Bleaching, dyeing finishing and printing. Is not stable at extreme pH range.
Density 0.9 g/cc
Ionicity Nonionic
pH (10%) 7 ± 1
Solubility Dispersible in cold water
Storage Good for at least 12 months. Do not store in direct sun. Sensitive to frost.

PROPERTIES & USES:

  1. Stable in pH range of 2-12.
  2. High stability towards electrolytes.
  3. The product is nonionic and can be used with anionic and cationic textile
    auxiliaries and dyestuffs.
  4. Excellent antifoam for all kinds of textile preparation, bleaching, dyeing,
    printing, coating and finishing processes, at pH range of 2-12 and in all
    temperature range including HT dyeing.
  5. AVCO-ANTIFOAM NS-300 is an excellent bubbles breaker and deareating agent for
    aqueous coating paste. The product is not causing any deterioration in the film
    properties and sticking power of the coating polymers.
  6. Effective in many aqueous processing operations, including high temperature
    systems.
  7. AVCO-ANTIFOAM NS-300 is used for preventing foam and for destroying existing
    foam.
  8. Excellent compatibility with many types of chemicals and with hard water.
  9. Non flammable.
  10. Non silicone antifoam.
  11. AVCO-ANTIFOAM NS-300 unlike silicone anti-foams will not cause problematic
    silicone grease build up on walls of equipments.

APPLICATION:

  1. Before use,pre-dilute the product with luke warm water (35-40°C) while stirring at a ratio of 1:4-1:9.
  2. If the pre-mix is used after several days the emulsion should be stirred again.
  3. Amount of application depends on type of process. Use of 0.1-0.5 g/l is sufficient in most cases.
  4. AVCO-ANTIFOAM NS-300 should be added to the bleaching or dyeing machine before the heating up step. Do not add the product to hot liquors above 70°C.
  5. AVCO-ANTIFOAM NS-300 is an excellent defoamer for pigment, reactive and disperse printing pastes. Use 0.4-0.8 g/kg.
