What are the magical effects of coating defoamer
The coating defoamer is composed of a variety of organic hydroxyl compounds, synergists, fatty acid ethers and lipids. It has strong defoaming and anti-foaming functions, does not contain mineral hydrocarbons, and has good compatibility with foaming media; the effect is stable during the storage period. Its efficacy can quickly and cleanly remove a large amount of harmful foam generated by the papermaking coating during the pump, screen and coating process during the air knife and scraper coating.
1. This product will not cause changes in the consistency of the coating. In the coating process, it can quickly and cleanly remove fine bubbles without pinholes, spots and fish eyes, ensuring the quality and beauty of the coated paper.
2. The method of use is simple, there is no resin barrier phenomenon, and it does not contain amino compounds, silica, silicon, oil and other chemical components that cause resin barriers. It plays a strong anti-foaming and defoaming role in various temperature ranges.
Coating defoamers are suitable for: coating, papermaking coating sizing, coating coatings, printing pictorial paper after calendering, deinking and washing, defoaming and degassing in paper coating polymer systems, coated paper, pulp defoaming, paper surface sizing and pressing process, glue, defoaming in coating processes, defoaming produced by deinking processes, use in the wet end of paper machines, degassing and defoaming in the paper production process, etc.
