  The more defoamer added, the better the effect. In fact, the higher the added amount, the better. Take water-based coatings as an example. Adding too much defoamer will cause shrinkage, oiliness, etc., and it contains silicon. Adding too much defoamer will also affect readability. Conversely, if the added amount of defoamer is too low, it will also affect the effectiveness of the defoamer due to insufficient addition. Then, China Peg-12 Dimethicone Company will introduce the strategy of using defoamer:

  The addition amount of defoamer is generally 0.1%-0.3%. Of course, the specific addition amount depends on the test situation. For example, high viscosity latex paints are difficult to defoam and have many foam stabilizing factors. The additional amount should be higher. You can give us feedback when you sample, so as to help you determine the most appropriate amount of addition.

  High-temperature printing and dyeing defoamers need to have two main properties: they can ensure constant working performance at high temperatures, and lasting foam suppression; and maintain chemical properties. It is also these two properties that only high-temperature printing and dyeing defoamers can work normally in the printing and dyeing industry. Defoamer can withstand a high temperature of 130℃. This type of defoamer is composed of polysiloxane, modified polysiloxane, white carbon black, dispersant, and stabilizer, etc. It can maintain very low concentration. Good anti-foaming effect; long anti-foaming time; suitable for defoaming in high-temperature dyeing; good product stability, not easy to demulsify and bleach oil.

  Through the above introduction,China 1,3,5,7-Tetramethylcyclotetrasiloxane Company hopes that you can simply refer to the content of this article in future use.
