Waterborne paint defoamer! Solve your bubble troubles
摘要：Why are water-based coatings prone to foam? What are the advantages of water-based coating defoamer?
1. Reasons for foaming of water-based coating defoamer:
1) During the coating process, air is mixed to cause foaming.
2), PH value has an effect on the foam, the higher the PH value, the more adverse to foam control.
3) Fine pigment particles lead to bubbles, and organic pigments such as carbon black and phthalein blue in pigments may lead to bubbles.
4), the various materials in the water-based coating formula affect each other, such as containing surface active ingredients, so it is easy to cause foaming.
The basic principle of bubbles in water-based coatings is the following process, under normal circumstances, after spraying, the coating in the process of forming the paint film due to the role of surface tension, bubbles can rise to the surface of the paint film, heating bubbles rise, expand, until the surface breaks, and then after leveling to get a flat paint film. Therefore, in the production formula of water-based coatings, anti-foaming agents for coatings are added to control the foam, giving the coating good construction and leveling property and good paint film effect.
2, the advantages of coating defoamer
1), excellent defoaming effect;
2), with lasting defoaming and foam suppression;
3), in the water-based system is easy to disperse, not easy to shrink;
4), suitable for a wide range of PH values (acid and alkali resistance).
The company's coating defoamer AR-19 is suitable for almost all water-based systems. Easy to disperse, with efficient defoaming and lasting foam suppression.
