Handheld LEDUV curing for car paint repair application

Can car touch-up paint be cured with a UV light?

Ultraviolet (UV) flashlight curing is a relatively new technology for automotive touch-up paint. Traditional automotive touch-up paint typically requires a long natural drying time or accelerated drying using baking equipment. With technological advancements, UV curing technology has begun to be applied to the automotive touch-up paint industry. This method can significantly shorten paint drying time, improve application efficiency, and enhance paint quality. Below, we will provide a detailed introduction to the application of UV flashlight curing in automotive touch-up paint.

The principle of UV curing technology

UV curing is a process in which ultraviolet light triggers a reaction in the light-curing components of a paint. When UV light strikes the surface of certain types of paint, the photoinitiators in the paint absorb the UV energy and activate a chemical reaction. This reaction crosslinks the molecular chains in the paint, rapidly solidifying it into a hard coating. Compared to traditional drying methods, UV curing does not require high temperatures or long waiting times, resulting in faster curing speeds and significantly improving touch-up efficiency.

Fast curing: UV curing greatly shortens the drying time of the paint surface, and curing can be completed in a few seconds to a few minutes, which can save a lot of time compared to traditional drying methods.

Improve work efficiency: Due to the fast curing speed, the use of UV flashlights can speed up the entire touch-up process, making the repair work more efficient. This is especially true when multiple repairs are required.

Reduce pollution: The UV curing process does not require high-temperature baking, which can effectively avoid the impact of high temperature on the car paint and the surrounding environment and reduce the emission of harmful gases.

Improved coating quality: UV-cured paint films are generally harder, more abrasion-resistant, and have better scratch resistance. The UV-cured paint surface also has a higher gloss, providing a better decorative effect.
