Effective Solution for Foaming in Rosin-Based Inks

Foaming in rosin-based ink production and application can negatively impact print quality and operational efficiency. Bubbles may cause surface defects such as pinholes, spots, or uneven coating, while reducing ink flow and adhesion. To address this challenge, Chemi Tech has developed specialized defoamers tailored for rosin-based inks, capable of rapidly eliminating foam and suppressing its reformation.  

Chemi Tech defoamers feature a unique formulation with excellent compatibility in rosin ink systems, ensuring no adverse effects on color, viscosity, or drying properties. Their mechanism involves disrupting foam surface tension to accelerate bubble collapse. Moreover, these defoamers maintain stable performance under high-temperature or high-shear conditions, making them suitable for gravure, flexographic, and other printing processes.  

For optimal results, add Chemi Tech defoamers directly during ink production or formulation at a recommended dosage of 0.05%-0.5%, adjustable based on foam severity. The product has been widely adopted in packaging and label printing industries, with users reporting fast foam knockdown and long-lasting performance, significantly improving production yield.
