Surface tension is a critical factor in the performance of many liquids, and in the context of inkjet printing, it dictates everything from droplet stability to jetting accuracy. Understanding how surfactants can manipulate surface tension is key for formulators aiming to create high-quality inkjet inks. This article explores the science behind surface tension and highlights how our modified acetylenic diol surfactant, a premium wetting agent, provides essential benefits for inkjet ink applications.

Surface tension arises from the cohesive forces between molecules in a liquid. At the surface, these forces are unbalanced, creating a net inward pull that causes the liquid to minimize its surface area, forming droplets. For inkjet printers, this phenomenon is a double-edged sword. While droplets are necessary, uncontrolled high surface tension can lead to poor jetting performance, irregular drop formation, and print defects. Surfactants, by their very nature, are surface-active agents that disrupt these cohesive forces, thereby reducing surface tension.

Our modified acetylenic diol surfactant is a nonionic molecule with a unique structure that allows it to effectively migrate to the air-liquid interface of the ink. Here, it lowers both static and dynamic surface tension. Lowering static surface tension ensures that when the ink is not actively being jetted, it remains stable. Critically, lowering dynamic surface tension—the surface tension during fluid motion—is paramount for consistent jetting at high speeds. This property helps prevent the aforementioned print defects, ensuring that each droplet is precisely formed and delivered to the substrate. As a leading manufacturer of specialty chemicals, we focus on developing solutions that address these specific technical challenges.

The benefits extend beyond just surface tension reduction. This wetting agent also offers excellent foam control, preventing the entrainment of air bubbles that can disrupt jetting and clog nozzles. Its formulation is silicone-free and oil-free, ensuring broad compatibility within complex ink formulations. For businesses looking to optimize their inkjet inks, understanding the role of a high-quality wetting agent is crucial.
