How to Choose Defoamers for Inks: Chemi Tech Professional Solutions

Foam formation during ink production and application can severely impact printing results. Selecting the right defoamer is critical, and Chemi Tech's industry-specific solutions effectively address this challenge.  

Compatibility is the primary consideration. Ink formulations contain complex components like resins and solvents. Chemi Tech defoamers feature tailored molecular structures that ensure rapid foam collapse without affecting color or viscosity.  

Efficiency matters significantly. High-speed printing or agitation generates microfoams that conventional defoamers may fail to control. Chemi Tech products offer long-lasting foam suppression at low dosage (typically 0.1%-0.5%), ideal for offset and gravure processes.  

Temperature resistance is another crucial factor. Ordinary defoamers degrade under heat, while Chemi Tech's high-temperature variants remain active above 80℃, suitable for UV inks and demanding conditions.  

Users should select Chemi Tech formulations based on ink type (water/solvent-based) and processing parameters. Laboratory trials help determine optimal dosage, significantly reducing production costs while maintaining consistent quality.
