Myanmar Differences in water-based mineral oil paint defoamer(2)





The water-based mineral oil paint defoamerhas 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


Polyether polyester modified organosiloxane
An organic polysiloxane with a comb like structure. N+m is about 50-250, and the molecular weight is controlled between 1000-150000. Its compatibility is adjusted by polyethers and polyesters, and the longer the chain, the better the phase compatibility. Polyether modifications are the most common in this category, typically using ethylene oxide and propylene oxide. With the increase of the content of ethoxy groups, their compatibility with water also improves, so it is also possible to synthesize water-soluble siloxane type leveling agents. Ethylene oxide and propylene oxide can be used alone or mixed to control hydrophilicity and lipophilicity. If both ethoxy and propoxy groups are contained, a silicone based leveling agent for both water and oil use is prepared,

Application and selection of water-based mineral oil defoamers:

替换城市  Waterborne mineral oil paint defoamer 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.
