Product catalog summary
Overview of UV-LED-Curing Epoxy Adhesives
UV-LED-curing epoxy adhesives offer advanced reliability, high temperature resistance, low shrinkage, and low ionic content. They also feature high glass transition temperatures, making them suitable for various applications, including precision optics and lens bonding.

UV LED Equipment Benefits
UV LED equipment is characterized by high energy efficiency, less thermal radiation, long operating life, and no need for stand-by times or warm-up phases. These features contribute to reduced maintenance and energy costs, as well as lower thermal stress on heat-sensitive substrates.

Advantages of LED Technology
LED technology provides significant energy efficiency, reduced maintenance, and long operating life (over 20,000 hours). It also minimizes thermal radiation, reducing thermal stress on substrates, and eliminates the need for stand-by times and warm-up phases.

Epoxy Adhesives Advantages
Epoxy adhesives are reliable against environmental effects, withstand wide temperature excursions, and have high glass transition temperatures. They offer dry, tack-free surfaces, excellent optical characteristics, low shrinkage, and low ionic content. They can be customized for flexibility or hardness, depending on the application.

UV-LED Curing Technology
Recent advancements in photoinitiators allow cationic curing epoxy systems to harden quickly with UV-LED light. This technology can be integrated into existing UV bonding processes, offering faster curing times comparable to light-curable acrylates.

Customized Solutions
Panacol provides tailored adhesive solutions for unique applications. Their adhesives can be customized to meet specific requirements, and they offer support for further information.

Hönle UV-LED Curing Technology
Hönle's UV-LED lamps are optimized for curing Panacol's Vitralit® adhesives. They offer various intensities and wavelengths, ensuring efficient curing processes. Typical curing times vary based on intensity and adhesive type, with full curing achieved after 24 hours.

Equipment and Specifications
Hönle offers a range of UV-LED equipment, including LED Spot 100 and LED Powerline LC, with varying intensities and configurations to suit different applications. These systems are adaptable and can be combined for larger irradiation areas.
