In the printing industry, the quality of ink is directly related to the aesthetics and quality of printed materials. However, ink often produces foam in the production and use process. These foam will not only affect the fluidity and uniformity of ink, but also reduce printing efficiency, increase energy consumption, and even lead to printing surface defects. Therefore, the application of ink defoamers is particularly important.

Defoamer for printing ink is a chemical substance that can effectively eliminate foam in printing ink. It improves the texture of ink and ensures printing quality by uniformly dispersing it in ink binders such as vegetable oil, mineral oil, synthetic resin, and solvents. In the printing process, the ink needs to maintain a uniform texture, and the production of foam will destroy this uniformity and affect the final effect of the printed matter.

Defoamers for printing inks are not only suitable for oily inks such as UV varnish, UV ink, oily screen printing ink, etc., but also widely used for water-based inks. In the process of ink grinding, ink mixing and printing, it is easy to produce a lot of foam due to the introduction of air. These foam will not only affect the fluidity of the ink, but also leave bubbles on the printing surface, affecting the beauty and quality of the printed matter. Therefore, adding an appropriate amount of defoamer can quickly eliminate foam and ensure ink uniformity and printing quality.
