A defoamer, or anti-foaming agent, is a chemical additive that prevents the formation or breaks down existing foam in a liquid system by destabilizing the air bubbles that form the foam. These substances are crucial in many industries, including food processing, pulp and paper manufacturing, paint production, and wastewater treatment, where foam can impede production, reduce product quality, and cause operational disruptions. These are a class of chemical additives that suppress and eliminate foam formation. They function by disrupting the structural stability of bubble membranes and are widely used across multiple industrial sectors, including coatings, inks, wastewater treatment, food processing, and adhesives.
Chemical Name :
anti-foaming agent(Antifoams)Application :
Emulsion paint ,Water-soluble paint (High-Gloss, Semi-Gloss, Exterior, Interior) , Water-based inks, water-based adhesivesProduct model :
K5602AAppearance :
Translucent liquidFoam is an unstable thermodynamic system formed by gas dispersed within a liquid or solid medium. In numerous industrial production processes, excessive foam readily forms due to factors such as agitation, vibration, coating application, or chemical reactions. This foam leads to reduced production efficiency, product defects, wasted equipment capacity, and ultimately diminished product quality. Defoamers are additives specifically designed to address this issue, with their core functions being:
(1) Rapidly breaking down existing foam (foam breaking);
(2) Long-term suppression of foam reformation (foam inhibition).
K5602A from China AAB Group is a defoamer for water-based coatings. It can be used in color paint formulations, and has good compatibility with pure C emulsion systems, phenyl C emulsion systems, PU dispersions, hybrid systems, resins and other water dilutable systems.

APPLICATION
K5602A is used in aqueous systems with excellent foam inhibition and defoaming properties and solves the risk of shrinkage. It can be used in the below fields:
• Industrial Coatings
• Emulsion paint
• Water-soluble paint (High-Gloss, Semi-Gloss, Exterior, Interior)
• Water-based inks, water-based adhesives
CHARACTER
• For water-based high-gloss paints
• Universally applicable to various resins
• Less cratering and excellent gloss retention
• Excellent foam suppression effect
RECOMMENDED LEVELS
0.1-1.0% Additives (purchased form) based on total formulation.
The above data are empirical and the optimum dosage should be determined through a series of tests.
INCORPORATION and PROCESSING INSTRUCTIONS
For optimal results, it is recommended to add prior to grinding or mixing to achieve the best foam suppression effect; if added later, ensure thorough mixing.
PACKING and STORAGE
-25kg iron drum with inner coating
-180kg ring plastic drum
-Layering may occur at temperatures below 5 °C. Heat to 20 °C and mix thoroughly before use.
-Storage is not recommended for more than 12 months.
Although defoamers play a supporting role in formulations, their function is crucial. They serve as indispensable key additives that ensure the smooth operation of modern industrial production and enhance the quality of final products. With increasingly stringent environmental regulations and continuous technological advancements, defoamers are evolving toward greater efficiency, multifunctionality, environmental friendliness, and system-specific applications.China AAB Group offering cost-effective defoaming agents, support product customization, provide customers with value-added products and services.
