Qatar Types of Free of silicone defoamers for Beer Bottle Cleaning How much is it (3)







Leveling principle
The compatibility of acrylic leveling agents is an important indicator of their ability to control the surface state of the coating film. The compatibility is too good to dissolve in the coating film, which will not form a new interface on the surface of the coating film and provide no leveling effect; Due to poor compatibility, it is impossible to uniformly distribute on the surface of the coating film, which can gather together and easily cause shrinkage defects. It can reduce the gloss of the coating film and produce adverse side effects such as fog and shadow. Only with ideal controlled compatibility can a new interfacial layer be formed on the surface of the coating film, playing a leveling role

Qatar It is also worth noting how to select  Free of silicone defoamers 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
