Estonia Differences in water-based mineral oil paint defoamer(1)
Estonia Advantages of water-based mineral oil in water-based paint systems:
Organosilicon type paint defoamer can reduce tension on the surface of coatings, have excellent defoaming and foam inhibiting capabilities, and have little effect on the gloss of the coating film under different environmental factors. However, when not used properly, they can cause poor recoating performance, uneven surface such as film shrinkage, and polyether type defoamers have high compatibility requirements and weak defoaming capabilities.
Dispersant is a kind of interfacial active agent that has both opposite properties of lipophilicity and hydrophilicity within the molecule. It can uniformly disperse solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in liquids, while also preventing particle sedimentation and condensation, forming amphiphilic reagents required for stable suspensions
The water-based mineral oil paint defoamerhas a fast defoaming speed and a foam inhibiting effect of up to several hours, which is also well matched with the foam system. It can be carried out in harsh environments such as high temperatures and strong alkalis, with good results. After use, there will be no phenomena such as oil bleaching and demulsification
