Polydimethylsiloxane
Although it has good surface state control capabilities, it has many shortcomings, such as poor compatibility, which can affect the gloss of the coating film, and often lead to shrinkage, interlayer adhesion issues, and so on. The molecular weight of polydimethylsiloxane is different, and its compatibility and use are also different. Compared with silicone oil, organic modified polydimethylsiloxane has obvious advantages, not only retaining the advantages of siloxane, but also overcoming its disadvantages with modifiers, exerting many special functional effects. The key to the performance and use of modified siloxanes is their molecular weight, type, type of modified compound, and position in the molecule. There are many ways to modify them

viscosity-reducing

The main component of mineral oil ink defoamer Pakistan is mineral oil, or any other oil that is insoluble in the foaming medium, as the carrier, accounting for approximately 50% to 70%. Its specific gravity is the key. Too much will affect its solubility and emulsification, while too little will affect its stability and effectiveness.

matte

Inorganic hydrophobic particles account for about 10% of the total, and they are evenly dispersed in mineral oil, which is one of the key factors because their hydrophobic strength determines the effectiveness of defoaming performance, which can help ink defoamer Pakistan factors reach the surface of the liquid film more easily, allowing the defoaming agent to quickly blend with the liquid film to increase defoaming speed.
