UV curing defoamer

In today's material processing and production fields, UV curing technology is playing an increasingly important role, and the corresponding UV curing defoaming agent has also quietly entered people's field of vision, solving difficult foam problems for many industries.

1. What is UV curing defoamer

UV curing defoamer is an auxiliary agent specially developed for UV curing system. During the UV curing process, since the system contains multiple components such as active diluents, oligomers, photoinitiators, etc., it is very easy to mix in air and form foam during stirring, coating and other operations. This defoamer is like the "nemesis" of foam. It can quickly reduce the surface tension of the liquid, make the foam film fragile, and then break and disappear, ensuring the smooth progress of the UV curing process.

2. Showing off in the coating industry

Furniture coatings

In furniture manufacturing, beauty and durability are both indispensable. UV-curing coatings are widely used due to their advantages such as fast curing and high hardness. However, if foam is generated during the coating process, pinholes, pitting and other defects will appear on the dried paint film, seriously affecting the appearance of the furniture. UV-curing defoamers can be added before the coating is applied to effectively eliminate the foam generated by stirring, so that the paint film on the surface of the furniture is smooth and flat, and the color is uniform, which greatly improves the quality and market competitiveness of the furniture.

Car repair paint

Cars are inevitably scratched in daily use and need to be repaired to restore their original appearance. UV-curing repair paint can dry quickly and reduce maintenance time. However, when spraying, the high pressure of the spray gun can easily cause foam. If not handled, bubbles and flow marks will appear at the repaired part, and the connection with the original car paint will be unnatural. The intervention of the defoamer ensures the uniform coating of the repair paint, making the repaired car paint perfect as before and ensuring the beauty of the car.

3. Key guarantees in the electronics field

Electronic equipment is becoming more and more sophisticated, and the requirements for its manufacturing materials are extremely high. UV-curing adhesives are often used in circuit board printing, electronic component packaging and other links. The foam generated by these adhesives during the dispensing and coating process may cause uneven distribution of glue, affect the bonding strength of electronic components, and even cause faults such as short circuits. UV-curing defoamers can accurately eliminate tiny bubbles, ensure that the adhesive fits tightly to electronic components, ensure the stability and reliability of electronic products, and lay a solid foundation for the rapid development of modern electronic technology.

4. A powerful assistant in the printing and packaging industry

Paper printing

Exquisite paper products such as book covers and packaging boxes are often printed with UV-curable inks. During the printing process, the high-speed circulation of ink and the rotation of the rollers are prone to foaming, which will cause blank spots and blurred lines in the printed pattern, reducing the quality of the printed product. After adding the defoamer, the ink can be smoothly transferred to the paper product, presenting a clear and bright pattern, meeting people's growing demand for high-quality paper products.

Plastic packaging printing

Plastic film is used for packaging of food, daily necessities, etc., and the printing ink on it needs to be cured quickly. UV-curable inks are very useful here, but foam problems often occur. Once foam appears, the logo and pattern on the packaging will be incomplete, which not only affects the appearance but may also mislead consumers. Defoamers effectively solve this problem, helping the plastic packaging printing industry to produce flawless packaging products and ensure the attractiveness of goods on the shelves.

Although UV-curing defoamers are inconspicuous, they work silently in many key industries. With their excellent defoaming performance, they ensure product quality and promote the development of various industries towards higher quality and more refined directions, making all kinds of products in our lives more perfect.
