Due to the relatively low VOC content of water-based coatings, they are increasingly popular among consumers. However, for some water-based paints, we will find that if not treated in time, it is easy to produce bubble holes and fish eyes, but some will not. What’s the secret in the middle? The answer is whether to add a water-based paint defoamer.

What additives are included in water-based coatings

Water-based coatings are mainly prepared using water as the solvent. Various additives are added during the preparation process, such as driers, antifungal agents, and fungicides. , cosolvents, thickeners, etc., to enhance the performance of water-based coatings.

Water-based coating defoamer

Why does water-based paint bubble?

From the above additives, we can see that most of the additives contained in water-based coatings are surfactants, which can easily cause foaming. Especially during the mixing process of paint production machines, it is easy to produce a large amount of foam, which is difficult to eliminate. So why some foam after use or why some don’t foam during use? The difference lies in whether there is a water-based paint defoamer added or not.

Water-based paint defoamer can solve the foam problem of water-based paint, and has a good defoaming and foam suppression effect. It can also solve the foam problem of paint. Therefore, the reason why some water-based paints do not foam is because they contain water-based paint defoaming agents.

Adding water-based paint defoaming agents to water-based paints can bring the quality of the paint to a higher level. It is a good partner for water-based paints.

Advantages of water-based coating defoamer

Water-based paint defoamer uses organic polyether ester as the main component and is made through a special process.

The advantages are: good emulsification, strong dispersion, and fast defoaming and suppression. Aiming at the foam problem of water-based coatings, it will not have any adverse effects on the system and will not easily cause oil drift and demulsification. Easy and simple to use. Source manufacturer, high cost performance and more advantageous price.
