How to Choose Chemi Tech Defoamer to Prevent Ink Cratering

In the printing industry, ink cratering is a common surface defect that significantly impacts product quality. Selecting the appropriate defoamer is crucial to address this issue. Chemi Tech defoamers， with their unique chemical structure, effectively suppress foam formation while maintaining compatibility with ink systems, thereby eliminating cratering.  

Ink cratering often results from poor compatibility between defoamers and inks. Chemi Tech defoamers are specially designed to rapidly penetrate foam films and destabilize them without disrupting ink components. Their low surface tension and excellent dispersion properties ensure defoaming without interfering with ink leveling, preventing crater formation.  

For different ink systems, Chemi Tech offers tailored defoamer solutions. For instance, high-viscosity inks require highly penetrative variants, while water-based inks benefit from hydrophilic-modified products. Users should select the appropriate type based on ink composition, printing speed, and environmental conditions for optimal results.  

Additionally, the dosage of Chemi Tech defoamers must be precisely controlled. Excessive use may degrade ink performance, while insufficient amounts fail to eliminate foam entirely. Small-scale testing is recommended to determine the ideal ratio, typically ranging from 0.1% to 0.5%.  

In summary, the correct selection of Chemi Tech defoamers effectively prevents ink cratering and enhances print surface quality. Their stable chemical properties and broad applicability make them an ideal choice for the printing industry.
