Laos Differences in water-based mineral oil paint defoamer(3)




Defoaming agents should have the following properties: ① strong defoaming power and low dosage; ② Adding to the foaming system does not affect the basic properties of the system, i.e. does not react with the defoaming system; ③ Low surface tension; ④ Good balance with the surface; ⑤ Good heat resistance; ⑥ Good diffusion and permeability, high positive spreading coefficient; ⑦ Chemical stability, strong oxidation resistance; ⑧ Good gas solubility and permeability; ⑨ Low solubility in foaming solutions; ⑩ No physiological activity, high safety.

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.
