- What is the reason for the oil slick of defoamerAccidents can also occur during the use of defoamers, and oil slicks are common. What is the reason for the oil slick of defoamer?This is due to its own materialDefoaming agents are mostly mixtures, mainly carriers or additives of defoaming agents. There are many types of defoamers, such as silicone2023-03-09
- Active Components and Properties of Organosilicon Defoamers1. Active ingredient: The main ingredient of silicone defoamers is linear polysiloxanes (also known as silicone oil) that can maintain liquids at room temperature as active agents. The main types of polysiloxanes are: polydimethylsiloxane, fluorosiloxane, and ethylene glycol siloxane.Silicone oil is2023-03-02
- Knowledge points of selecting and using paint defoamerVarious high-speed mixers need to be used in the coating manufacturing process, such as three-roller machine, sand mill and ball mill. Various methods used for coating, such as air spraying, airless spraying, roller coating, flow coating and spray coating. In these processes, the free energy of the2023-02-21
- Leveling agent is a coating agent that can make the coating form a flat filmLeveling agent is a commonly used coating agent, which can promote the formation of a flat, smooth and uniform coating film during the drying process. A class of substances that can effectively reduce the surface tension of the finishing liquid and improve its leveling and uniformity. It can improve2023-02-21
- Attentions when using defoamer for waterborne coatings1) Before use, it must be fully mixed. Generally, it can be added directly without water dilution. If it needs to be diluted, it can be prepared and used immediately. Most defoaming agents cannot be directly added to the diluted water-based coating. Generally, they should be added when the viscosity2023-02-21
- Application of molecular structure and action mechanism of leveling agent in coatingsLeveling agent is a common coating additive, which can promote the formation of a flat, smooth and uniform coating film during the drying process. The flatness of the coating film is called leveling. There are many types of leveling agents, and different types of leveling agents are used for differe2023-02-21
- Organosilicon defoamer is an important type of defoamer1. The local surface tension of foam decreases, resulting in the bursting of foam. The origin of this mechanism is that alcohol or vegetable oil is sprinkled on the foam. When it is dissolved into the foam liquid, the surface tension will be significantly reduced. The part with reduced surface tensi2023-02-21
- Precautions for application of defoamer for coatingDefoaming agent for coating is a compound defoaming agent refined by special process from ether, fat, alcohol and other substances. Defoaming agents for paints are dispersed in water-based systems, with strong self-emulsification, good defoaming and lasting foam suppression, especially for water-sol2023-02-21
