Verbesserung der Lackleistung mit Lackentschäumern: Ein wichtiger Bestandteil für gla - shubham565 - 09.10.2025
In the coatings and paints industry, achieving a flawless surface finish is a top priority. One of the most common challenges in paint formulation is foaming, which can lead to surface defects, poor coverage, and uneven appearance. To counteract this, manufacturers rely on paint defoamers – critical additives that prevent foaming during production, application, and drying. These specialty agents ensure that paints retain their desired texture, gloss, and durability, making them essential for both industrial and decorative coatings.

Foaming in paints can occur at various stages—during mixing, stirring, or application—due to surfactants and other stabilizers. Excessive foam not only disrupts uniform pigment distribution but also traps air bubbles in the film, leading to craters, voids, and reduced film strength. Paint defoamers work by destabilizing foam bubbles, promoting their rapid disintegration and preventing the formation of new ones. These additives typically consist of hydrophobic solids dispersed in a carrier liquid. They are carefully formulated to remain compatible with various coating types, including water-based, solvent-based, and powder coatings.
The types of paint defoamers vary depending on their chemical composition and application requirements. The most common categories include mineral oil-based, silicone-based, and polymer-based defoamers. Silicone-based defoamers are widely used due to their strong and long-lasting foam control, making them ideal for high-performance coatings. Mineral oil-based defoamers, on the other hand, are preferred in cost-sensitive formulations and offer moderate efficiency without compromising gloss or film clarity. Polymer-based defoamers, especially those for waterborne coatings, are gaining popularity because they offer improved compatibility and fewer surface defects.
The growing demand for water-based and environmentally friendly paints has significantly influenced the development of next-generation defoamers. As regulators worldwide set stricter limits for volatile organic compounds (VOCs), paint manufacturers are increasingly turning to sustainable additives that meet environmental standards. Today's modern defoamers are engineered to achieve high effectiveness even at low concentrations, thus minimizing environmental impact while maintaining excellent foam suppression and surface quality.
