The Advantages of Water-Based Paint Defoamers
During the production and construction of paints, foam problems often occur, which is mainly attributed
to its unique formula and production process. In order to solve this problem,
water-based paint defoamers came into being and played an increasingly important role in the paint industry.
1. The basic concept of water-based paint defoamers
Water-based paint defoamers are a type of defoamer specifically used in paint systems. The main components
are polyethers, fatty acids, mineral oils, dispersing solvents, hydrophobic silica,
etc. It can quickly and effectively eliminate the foam generated during the production and use of paints to ensure
the smooth progress of coating.
2. Advantages of water-based paint defoamers
High-efficiency defoaming and anti-foaming ability:
Water-based paint defoamers have the ability to quickly penetrate the foaming medium, effectively reduce the
surface tension of the foaming material film, and promote the rupture of foam.
At the same time, it can also reduce the surface activity of the foam and prevent secondary regeneration, thereby
achieving a lasting anti-foaming effect.
Good dispersibility and compatibility:
Water-based paint defoamers can be evenly dispersed in the system when used, without stratification or precipitation.
This allows it to better blend with other ingredients in the paint and will not affect the overall performance of the paint.
Excellent chemical stability:
Water-based paint defoamers can be used with raw materials such as water, mineral oil, vegetable oil, and organic
solvents without affecting their original performance.
It can be used stably in high temperature, strong acid, strong alkali, and high shear environments, and is suitable
for various harsh paint production environments.
Environmentally friendly and pollution-free:
Water-based paint defoamers usually do not contain harmful chemical elements such as phosphorus and sulfur,
and are harmless to human health.
It does not produce irritating odors during use, which meets the environmental protection requirements of the
modern paint industry.
Small addition, significant effect:
The addition amount of water-based paint defoamers is usually only 0.5%~1% of the product, but it can achieve
significant defoaming effects.
This avoids waste in production and saves cost.
No effect on paint performance:
Water-based paint defoamers are chemically stable and will not react with additives in paints.
Its use will not affect the basic properties of the paint, such as color, adhesion, and decorative effects, ensuring
the quality of coating.
Balanced defoaming and antifoaming performance:
Waterborne paint defoamers combine the characteristics of silicone and polyether defoamers, effectively
maintaining the balance between defoaming and antifoaming.
This enables it to exert a stable defoaming effect in various foaming environments.
3. Application scope of waterborne paint defoamers
Waterborne paint defoamers are not only suitable for waterborne paint systems, but also can be used in paints,
inks, paper coatings, rubber, adhesives and other industries. Its wide application
further proves its excellent performance and wide applicability.
4. Conclusion
In summary, waterborne paint defoamers play an increasingly important role in the paint industry with their high
efficiency in defoaming and antifoaming ability, good dispersibility and
compatibility, excellent chemical stability, environmental protection and pollution-free, small addition amount and
significant effect, and no effect on paint performance. With the continuous
development of the paint industry, the application prospects of waterborne paint defoamers will be broader.
