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,

Ethiopia It is also worth noting how to select  paint defoamer for beer bottle cleaning. Firstly, they must be insoluble in the foaming liquid and have a lower surface tension than the foaming liquid, so that defoamers can play a role. Then, it should have a certain affinity with the foaming liquid. The defoaming process is actually a competition with the foam production. Only by rapidly dispersing the effect in the starting liquid can we achieve the goal of defoaming. The active component of the defoamer is too hydrophilic to the foaming liquid and will dissolve; Too sparse and difficult to disperse. Only when intimacy is appropriate can effectiveness be good. Finally, it is not allowed to react chemically with the foaming liquid, otherwise harmful substances may breed and affect product performance
