Defoamer for Water-Based Inks: Selection and Application

In the printing industry, water-based inks are widely used due to their low volatility and ease of operation. However, foam generation during production often compromises print quality, causing poor ink flow, uneven coating, or equipment clogging. To address this, Chemi Tech has developed specialized defoamers for water-based inks, which rapidly eliminate foam and prevent its reformation.  

Chemi Tech's defoamers feature a unique formulation with excellent compatibility in water-based ink systems. They require minimal dosage and do not affect ink color or adhesion. The mechanism involves reducing surface tension to destabilize foam, ensuring long-lasting performance even under high-speed printing or agitation.  

For optimal results, the recommended dosage ranges from 0.1% to 0.5%, adjustable based on ink formulations and process conditions. The defoamer can be added during ink production or mixed thoroughly before use. It is suitable for various water-based flexographic and gravure inks, particularly excelling in high-shear or high-temperature environments.  

Choosing a professional defoamer is critical for maintaining print quality. With years of technical expertise, Chemi Tech delivers reliable solutions to enhance production efficiency and product performance.
