Defoaming agent analysis!

1 hydrophobic silicon nothing: This is a very important point, because the framework ofvery hydrophobic, and the existence of silicon is conflict, that they don't exist any harm,but when the bypass and silicone can make a methyl group had obvious contact on the surface level also because of this, so they just miss the hydrophobic methyl group, of course, different length of silicone is directly determines the different hydrophobicproperties.

2 the hydrophilicity and surface active agents are similar: of course, the most commonly used surfactant defoaming agent and hydrophilic defoamer directly have greatrelationship, of course is similar, but the overall value of silicone defoamer agent andsurface active agent can be directly replaced by two methyl siloxane group directlyregulation in the past, these will directly reflect the recent development of organic silicon defoamer products have begun to slowly try to use paint as assistant.

The 3 organosilicon defoamer to show strong: this point before being mistaken forwetting agent, but the ductility and not just rely on the surface tension decreased, of course, more important is the defoamer with far more than the organic fluorinesurfactant, and vice versa. Organic fluorine defoaming agent is organic silicon defoameris lower, the main advantages and disadvantages are occupied, so in the paint industry,the use of the additive effect will be very significant.
