With the new "Black&Light" adhesives, Panacol has developed a new adhesive technology: deep curing black epoxies. Black epoxy adhesives from Panacol's Vitralit® product range can now be cured with UV light sources in thicker layers, without resorting to secondary curing mechanisms.

Conventional black UV adhesives have a major disadvantage: the black color absorbs a high proportion of the UV intensity, which means that the energy needed to fully polymerize an adhesive can only penetrate a few micrometers. This results in surface “skin” formation on black adhesives, but not a complete cure. They must then be cured in a secondary thermal curing process at temperatures above 100°C.
Panacol的新型“ Black＆Light”技术可实现用LED紫外线能量的黑色环氧粘合剂的完整固化。固化深度的范围从几百微米到几毫米。这些粘合剂适用于电子制造中的封装，环形顶部或边缘键，以及需要高OD值（光密度）的光粘合系统。它们适用于光电应用，以帮助最大程度地减少反射并增强传感器传输值。
A typical manufacturing process using "Black&Light" technology can be as follows: The black adhesive is dispensed and cured with the appropriate wavelength and intensity. During the curing process, the “Black&Light” technology within the adhesive enables the UV rays to penetrate and complete a full cure. Once the adhesive polymerization is complete, the structure of the "Black&Light" technology prohibits light transmission, resulting in a fully cured adhesive system that remains irreversibly black.
“黑色和光线”技术与Panacol的许多Vitralit®环氧粘合剂兼容。可以创建自定义粘合剂解决方案，以适应灯光阻断和固化深度的独特要求。“黑色和光”粘合系统可以非常专门适用于相应应用的规格。
Another major advantage of the "Black&Light" adhesives is storage. Many single-component, black epoxies require deep frozen transportation and storage. The "Black&Light" epoxy adhesives can be stored and shipped at room temperature or under normal refrigeration.
