Water - based ink defoamer is an additive used to eliminate bubbles used in water - based ink.Water-based ink is a kind of ink with water as the medium, in the process of use may produce bubbles, these bubbles will affect the fluidity of ink, adhesion and drying speed. Therefore, the use of water-based ink defoamer can effectively eliminate these bubbles, improve the quality of water-based ink and use effect.# Water-based

Common water-based ink defoamer includes silicone defoamer and polyether defoamer. Silicone defoamer is widely used in water-based ink industry because of its excellent defoamer effect and stable chemical properties. Polyether defoamer has been widely used because of its low price and fast defoamer speed.

When using water-based ink defoamer, it is necessary to pay attention to its scope of application and use method. In general, it is recommended to conduct experiments first to determine the optimal concentration and conditions of use of defoamer. At the same time, it is necessary to avoid excessive use of defoamer, otherwise it may affect the performance and quality of ink.
