How to Choose Defoamers Without Affecting Ink Appearance?

Foam formation during ink production and application can compromise print results and efficiency. However, not all defoamers eliminate bubbles while maintaining the ink's original appearance. Chemi Tech specializes in developing defoamers with minimal visual impact, delivering tailored solutions for the industry.  

1. Critical Features of Low-Impact Defoamers  

An ideal ink defoamer should exhibit:  

- Superior compatibility: Seamless integration with ink systems, preventing haze or separation.  

- Rapid bubble-breaking: Instant foam collapse without visible residues or films.  

- Long-term stability: No alteration to ink gloss or color under storage or high-temperature conditions.  

2. Chemi Tech’s Technical Edge  

Through molecular optimization, Chemi Tech has developed ink-specific defoamer series. These products target foam interfaces precisely, achieving high efficiency at minimal dosage while preserving ink leveling, transparency, and hue.  

3. Application Performance  

In offset and gravure printing, Chemi Tech defoamers excel, particularly in high-transparency or pigment-rich inks. User reports confirm no adverse effects on printability or final visual outcomes.  

For optimal results, compatibility testing with ink formulations is recommended. Chemi Tech offers technical support to identify the ideal product, ensuring both productivity and print quality enhancement.
