Bolivia What are the advantages of paint defoamer for water-based cleaning agents(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





Many people often have concerns when choosing to add water-based defoamers in the production of cleaning agents. Do water-based defoamers affect the viscosity, transparency, and performance of cleaning agents. In fact, the detergent that plays a decontamination role is a surfactant. When the surfactant is dissolved in water, it removes dirt by emulsifying, dispersing, and solubilizing oil. Therefore, the decontamination ability of the detergent is not necessarily related to its viscosity and transparency, so the water-based defoamer does not affect its viscosity and transparency. The decontamination ability of cleaning agents is mainly related to the formula, that is, surfactants, such as anionic surfactants, have more foam than non-ionic surfactants. On the contrary, the defoamer of water-based cleaning agent can also reduce the production of foam and make foam disappear where it should not be, thus greatly improving the effect of cleaning agent.
