Defoamer FAG470 is widely used in industries with demanding foam control requirements, such as water treatment, coatings and inks, textile printing and dyeing, industrial cleaning, metalworking fluids, petrochemicals, and pulp and paper. Before use, gently stir the product in the container to homogenize it. It can be added directly or diluted with several times the amount of water before being added to the foaming system. It is recommended to use a metering pump for continuous addition to the key areas where foam is generated, to achieve optimal rapid defoaming and long-lasting foam inhibition effects. The specific dosage should be determined through small-scale tests based on actual conditions, avoiding excessive addition to prevent waste.
