-
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.
-
Effective in many aqueous processing operations, including high temperature
systems.
-
AVCO-ANTIFOAM NS-300 is used for preventing foam and for destroying existing
foam.
-
Excellent compatibility with many types of chemicals and with hard water.
-
Non flammable.
-
Non silicone antifoam.
-
AVCO-ANTIFOAM NS-300 unlike silicone anti-foams will not cause problematic
silicone grease build up on walls of equipments.
-
Before use,pre-dilute the product with luke warm water (35-40°C) while stirring at a ratio of 1:4-1:9.
-
If the pre-mix is used after several days the emulsion should be stirred again.
-
Amount of application depends on type of process. Use of 0.1-0.5 g/l is sufficient in most cases.
-
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.
-
AVCO-ANTIFOAM NS-300 is an excellent defoamer for pigment, reactive and disperse printing pastes. Use 0.4-0.8 g/kg.
