Plastic paint defoamer: a small additive with significant advantages
In the finishing process of plastic products, plastic paint defoamer is like a behind-the-scenes hero. With its unique performance,
it has brought many significant advantages to the production process and product quality, and plays a role that cannot be
underestimated in industrial production.
First of all, improving the appearance quality of the product is the most intuitive advantage of plastic paint defoamer
During the coating process of plastic paint, if there are bubbles, pinholes, bubbles, shrinkage holes and other defects will form on
the surface of the paint film after drying, which seriously affects the appearance of the product. Plastic paint defoamer can quickly
penetrate into the surface of the bubble film, reduce its surface tension, cause the bubbles to burst and escape, and make the surface
of the paint film smooth and without any defects. Whether it is a colorful plastic toy or a high-quality electronic equipment shell, after
being finished with plastic paint with defoamer added, it can present a more refined and professional appearance, greatly enhancing the
visual appeal of the product.
Secondly, plastic paint defoamer can improve production efficiency and reduce production costsIn the absence of defoamers
in order to reduce the impact of bubbles on the paint film, the production process often needs to slow down
the coating speed or increase subsequent grinding, repairing and other processes, which will undoubtedly extend the production cycle and
increase manpower and material costs. After adding defoamers, plastic paint can adhere to the plastic surface more smoothly during
coating, reducing the rework caused by bubble problems. At the same time, the use of defoamers can also make the paint utilization rate
higher, avoid the waste of paint caused by bubbles occupying space, save costs for enterprises from multiple links, and improve production
efficiency.
Furthermore, it can enhance the performance of the paint film and extend the service life of the product
The presence of bubbles will destroy the integrity of the paint film, making it easier for harmful substances such as moisture and dust to
invade the inside of the plastic substrate, resulting in problems such as paint film shedding and substrate aging. After the plastic paint
defoamer eliminates bubbles, the formed paint film is more dense and uniform, which can better play a protective role and improve the
adhesion, corrosion resistance, wear resistance and other properties of the paint film. This means that plastic products can better resist
the erosion of the external environment and reduce the possibility of damage in daily use, thereby extending the service life of the
product and bringing more lasting use value to consumers.
In addition, plastic paint defoamers have good compatibility and stability
It can be well mixed with different types of plastic paints, such as acrylic plastic paint, polyurethane plastic paint, nitro plastic paint, etc.,
and will not affect the chemical properties and performance of the plastic paint itself. Moreover, during storage and use, the defoamer
has stable performance and will not easily decompose or fail. It can maintain the defoaming effect for a long time, providing stable and
reliable guarantee for production.
In summary
Plastic paint defoamers have become an indispensable and important auxiliary agent in the coating process of plastic products with many
application advantages such as improving product appearance, improving production efficiency, enhancing paint film performance, and
good compatibility and stability, providing strong support for the development of the plastic industry.
