What are the functions of defoaming agents?
In addition to synergists, coating defoaming agents also contain many organic hydroxyl compounds. So what are the functions of coating defoaming agents?
1. Characteristics of coating defoaming agent
It has strong defoaming and other functions, and is not resistant to minerals and hydrocarbons. It has good compatibility with the foaming medium; within the storage period, the effect is extremely stable.
2. Effect of coating defoaming agent
Its function can quickly and cleanly remove a large amount of environmentally harmful foam that appears during air knife and scraper coating in papermaking paint pumps, screens, and coatings without causing changes in paint consistency and leaving the coating surface untouched. During the process, small types of foam can be quickly and cleanly removed, and pinholes, spots, fish eyes, etc. will not appear, thereby ensuring the quality and aesthetics of the coating.
