The water-based mineral oil No Foamhas a fast defoaming speed and a foam inhibiting effect of up to several hours, which is also well matched with the foam system. It can be carried out in harsh environments such as high temperatures and strong alkalis, with good results. After use, there will be no phenomena such as oil bleaching and demulsification

Application and selection of water-based mineral oil defoamers:
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
替换城市 Waterborne mineral oil No Foam are suitable for use in water-based systems with weak emulsifying properties, such as latex paints, coatings, adhesives, inks, and other systems with low emulsifying properties. They are easy to emulsify and form uniform distribution in water-based systems, thereby reducing the likelihood of surface defects such as shrinkage and loss of gloss, and also reducing microbubbles. However, it should be noted that mineral oils and waxes, which contain a small amount of organosilicon, and adopt special preparation processes, have excellent product storage stability, and are not prone to separation or sedimentation even after long-term storage.
