Foam formation during production, mixing, and application of latex paint often leads to film defects such as pinholes and craters, compromising surface appearance and protective performance. Traditional defoamers frequently suffer from poor stability, insufficient persistence, or compatibility issues, making it challenging to maintain consistent coating quality.

The market demands an efficient and stable defoaming solution. Chemi Tech specializes in coating additives and has developed a dedicated defoamer series for latex paint. Utilizing modified polysiloxane technology, this defoamer rapidly penetrates foam structures and disrupts surface tension, achieving quick defoaming and long-term foam inhibition.
The solution involves four steps: First, add 50%-60% of the defoamer during the grinding stage to suppress foam at the source. Second, incorporate the remainder during the mixing phase to ensure even dispersion. Third, employ low-speed stirring before application to avoid introducing new bubbles. Finally, conduct real-time inspections to guarantee smooth, defect-free films.
In one case, a coating manufacturer faced excessive foam in high-gloss interior paint production, resulting in significant surface defects. By adopting Chemi Tech defoamer KM-668 and following the stepwise method, foam control improved markedly—film smoothness increased by 90%, customer complaints dropped by 85%, and production costs were effectively managed.
Chemi Tech defoamers offer excellent compatibility and stability, suitable for various emulsion systems including acrylic, styrene-acrylic, and pure acrylic. Rigorously tested for performance across different pH and temperature conditions, they provide reliable technical support for coating enterprises.
