In the printing industry, ink is a key material for transmitting images and text, and its performance directly affects the quality of printed materials. However, ink often faces the problem of foam in the process of preparation, storage and use. These foam will not only reduce the fluidity and uniformity of the ink, but also may cause the printed matter to appear spots, fish eyes and other defects, seriously affecting the printing effect. To solve this problem, ink defoamers have emerged.

Ink defoamer is a chemical additive specially designed for ink system. Its main function is to quickly destroy the foam in the ink and prevent the regeneration of foam, so as to ensure the stability and printing quality of the ink. These defoamers act on foam through a unique mechanism, making bubbles break quickly and disperse in ink again, improving the leveling and adhesion of ink.

The key components of ink defoamers are diverse, including but not limited to organosilicon, polyether, mineral oil, etc. Each component has its unique technical characteristics. In terms of technical characteristics, ink defoamers need to have fast defoaming, long-lasting foam suppression, good compatibility and stability. Meanwhile, with the strengthening of environmental regulations, low VOC and biodegradable ink defoamers are gradually becoming the mainstream in the market.
