UV curing technology has been widely used in various industries, especially the use of UV curing lamps is indispensable. When choosing UV curing lamps, 365nm and 395nm wavelengths are the most common choices. So, what is the difference between them? What application scenarios is it suitable for? This article will provide a detailed introduction to the differences and applications of UV curing lamps at 365nm and 395nm.

 1、 The basic principle of UV curing lamp
        UV curing lamps emit specific wavelengths of ultraviolet light, triggering photosensitive chemical reactions in materials such as coatings and adhesives to achieve curing. This curing method has the advantages of fast, efficient, and environmentally friendly, and is widely used in industrial manufacturing, printing, electronic assembly, and other fields.

   2、 The technical difference between 365nm and 395nm
1. Spectral characteristics
-365nm wavelength: belongs to the UVA spectral range, with high photon energy that can trigger various photochemical reactions, making it highly effective in many applications that require deep curing.
-395nm wavelength: also within the UVA spectral range, but with relatively low photon energy, typically used for surface curing. The light penetration at a wavelength of 395nm is weak, but for certain materials, the light reaction efficiency is higher.

  3、 Application scenarios of 365nm and 395nm
1. Printing and Coating
-365nm UV curing lamps are commonly used in applications that require rapid drying and high hardness coatings, such as high gloss coatings, automotive coatings, etc.
-The 395nm UV curing lamp is more suitable for coating certain flexible and sensitive materials, such as flexible packaging materials, decorative films, etc.
2. Electronic manufacturing
In the packaging and assembly of electronic components, 365nm UV curing lamps are widely used to cure transparent adhesives and coatings to ensure high strength and durability. And 395nm UV curing lamps are mostly used for surface treatment of dark or opaque components.
3. Processing of optical components
Optical devices require extremely high precision in the curing process. The 365nm UV curing lamp is suitable for deep curing of optical adhesives, while the 395nm UV curing lamp is commonly used for curing surface coatings to ensure the stability of optical performance.
4. Medical device manufacturing
Medical devices require a highly stable and safe curing process. The 365nm UV curing lamp has a wide range of applications in curing medical adhesives and coatings, while the 395nm UV curing lamp is used for surface treatment of certain specific materials.

conclusion
It is very important to understand the characteristics and applicable scenarios of different wavelengths when choosing UV curing lamps. 365nm and 395nm UV curing lamps each have their own advantages and disadvantages. Enterprises should choose the appropriate wavelength according to specific application needs to achieve the best curing effect and production efficiency. With the continuous development of UV curing technology, the application range of these two wavelengths will become more extensive, providing more efficient and environmentally friendly solutions for various industries.
