UV Adhesives

UV adhesives are advanced acrylate- or epoxy-based resins that cure rapidly when exposed to ultraviolet (UV) light. Through polymerization under UV irradiation, these adhesives form strong, durable bonds within seconds — significantly accelerating production processes and improving efficiency.

Thanks to their instant curing, excellent transparency, and high strength, UV adhesives are widely used in industrial manufacturing, including electronics, medical devices, optics, glass, and plastics assembly. Their ability to deliver precise, clean, and consistent results makes them ideal for automated and high-volume production environments.

Our Vitralit^®  series offers a comprehensive range of UV-curing adhesives tailored to meet diverse application needs. Whether you require flexible, rigid, or hybrid bonding solutions, Vitralit^® products provide exceptional performance, reliability, and ease of processing.

Discover the power of our Black&Light technology – the innovative solution that enables full UV curing of black epoxy adhesives, even in think layers. Unlike conventional systems that rely on secondary curing mechanisms, Black&Light allows for complete, light-only curing using advanced UV LED technology.

This breakthrough opens new possibilities for process efficiency, design flexiblitiy, and material performance – especially in applications where speed, precision, and reliability are critical.

Black UV adhesives are opaque and protect sensitive components on printed circuit boards.

Dual-curing UV adhesives are used, for example, for bonding connectors

Dual-curing UV adhesives combine the speed of UV light curing with a secondary curing mechanism such as moisture or heat. This innovative technology ensures complete and reliable curing, even in areas where UV light cannot fully reach — for example, in shadowed or opaque bond joints. The first curing step occurs instantly under UV irradiation, providing immediate handling strength. The second curing mechanism — activated by moisture or heat — guarantees full crosslinking and long-term bond stability.

These UV dual-cure adhesives are ideal for complex assemblies in electronics, medical devices, optics, and automotive applications, where both precision and durability are essential. Our Vitralit® Dual-Cure series delivers fast processing, excellent adhesion to diverse substrates, and consistent performance in challenging industrial environments.

Depending on the adhesive formulation, both UV gas discharge lamps and modern LED UV light sources can be used for curing. LED light sources emit monochromatic light, while gas discharge lamps cover a broad UV spectrum, utilizing multiple wavelengths simultaneously. In contrast, the spectrum of LEDs is limited to a specific wavelength.

That’s why it’s essential to choose the curing system that matches your adhesive. We’re happy to support you in finding the perfect combination of adhesive and curing equipment!

In bandaging processes, the UV adhesive is cured using Hoenle’s LED Powerline.
