Efficiently Solve Drier Foaming Issues with Chemi Tech Defoamers: Precise Solutions and Applications

In the production and application of coatings, inks, and related products, the addition of driers often triggers persistent foam. This foam not only reduces the filling efficiency of production tanks, leading to decreased capacity, but also causes defects in the final film, such as craters, fisheyes, or unevenness, severely compromising product appearance and performance. Traditional defoaming methods often offer only temporary effects or poor compatibility, failing to address the root cause.

Chemi Tech focuses on this specific area, delving into the core mechanisms of foam formation. We have found that the active components in driers can alter the system's surface tension and potentially interact with other additives, thereby stabilizing foam. To tackle this pain point, we have developed a series of high-efficiency defoamers specifically for drier-containing systems. Our solution is based on a three-step strategy: First, rapid penetration and spreading to rupture the liquid film of existing foam. Second, its unique structure ensures good compatibility with the system, continuously suppressing foam regeneration. Finally, the product exhibits excellent stability with no performance degradation during storage and application.

The application procedure is clear and straightforward: Step 1, select one or several samples recommended by Chemi Tech based on your system fundamentals (e.g., resin type, solvent polarity). Step 2, it is advised to add the defoamer during the later stages of grinding/dispersion or during the let-down phase, typically at 0.1%-0.5% of the total formulation. Step 3, ensure adequate stirring for homogeneous dispersion, followed by regular production and testing.

We assisted an industrial coatings manufacturer in East China in resolving foam issues in their alkyd system caused by driers. The client experienced severe foam overflow on the filling line after drier addition, and the finished product showed visible pinholes after settling. After adopting our KT-328 series defoamer at the recommended dosage, foam during production was immediately controlled, and filling efficiency increased by approximately 15%. The resulting coating produced a smooth, even film with completely eliminated pinholes, and the customer expressed high satisfaction with the final coating quality.

Choosing Chemi Tech means you acquire not just a defoamer, but a systematic solution tailored to drier-induced foam. Our technical team is ready to provide customized product selection and process support, helping you achieve smooth production and卓越品质.
