This product is a kind of polysiloxane-polyether copolymer emulsion defoamer, which is mainly used to control the foams during the production of aqueous latex paint, especially suitable for use in the styrene - acrylate emulsion, pure acrylic emulsion, acetate ethylene emulsion.
In addition to that, this defoamer also can be used in the water-based ink, water-dilutable resin, waterborne epoxy resin, water-based colorant, sizing agent, etc., to control the foams.  

Characteristic
(1) Strong defoaming and foam suppressing ability, small dosage, no effect to the basic properties of the foaming system.
Good heat resistance, good chemical stability, non-corrosive, non-toxic, non-flammable, non-explosive, no adverse side effects.Comparable to the top quality product on market,while the price is much more affordable.

Instructions
Defoamers have excellent elimination and defoaming properties and can be added after the foam is generated or added to the product as a defoaming component. According to different usage systems, the defoamer can be added in an amount of 10 to 1000 ppm. The customer decides according to the specific circumstances.
  Defoamer products can be used directly or diluted. If it can be fully stirred and dispersed in the foaming system, it can be directly added without dilution. For dilution, follow the attachment dilution method. The method of directly diluting the product with water is not desirable, and it is prone to layered emulsion breaking, which affects the quality of the product. The company shall not be liable for the consequences of processing or using the product due to direct dilution with water or other incorrect methods.

Usage:  

Direct add to the foaming system to remove foams, or using together with other powdered additives after mixing well.

Recommended dosage: 0.1~1% of total amount, but the optimum dosage should be determined through the real test.
