On printing production lines, foaming in water-based ink is a common yet troublesome problem. Foam not only causes white spots and pinholes on the surface of printed materials, affecting color uniformity and pattern integrity, but may also cause poor pumping in printing equipment and even lead to production interruptions, directly reducing efficiency and yield. Many production teams have spent large amounts of time and cost on debugging and rework because of it.
To address this core pain point, Chemi Tech, drawing on in-depth research into ink systems and surface chemistry, has developed a series of high-efficiency water-based ink defoamers. Our solution is not a simple addition but is based on systematic analysis. First, our technical team analyzes the customer's specific ink formulation, printing speed, and equipment type to determine whether the root cause of foaming is excessively high system tension, overly strong mechanical shear, or an excess of foam-stabilizing substances. We then recommend a matching defoamer model. These products offer excellent compatibility and durability, quickly penetrate the foam film and break it while inhibiting foam regeneration, and they do not affect the gloss or adhesion of the ink.
The specific implementation steps are clear and well defined. The first step is sample testing; we provide small samples for customers to evaluate defoaming speed and durability under real working conditions. The second step is to determine the optimal dosage, usually 0.1%-0.5% of the total formulation, added during the high-speed stirring stage to ensure even dispersion. The third step is stability tracking to ensure stable performance during long-term storage and under different temperature and humidity conditions.
We once helped a company focused on packaging printing solve such a problem. When this company used a new ink formulation for high-speed printing, it repeatedly experienced missing local patterns and uneven color. By applying a specific Chemi Tech defoamer product and making process adjustments according to the steps above, the foam problem was brought significantly under control within 24 hours. Print quality returned to a stable level, the equipment ran smoothly, production efficiency was safeguarded, and the customer acknowledged the results.
Choosing Chemi Tech means choosing a reliable production safeguard. Our products are committed to ensuring that the foam problem in water-based ink no longer becomes an obstacle to your quality and efficiency.
