Henkel Corporation has introduced the next generation of Loctite® Indigo™ Visible Light Cure Adhesives formulated for improved performance in a broad array of medical bonding, potting and assembly applications.

Designed to cure in seconds upon exposure to light in the visible spectrum, these products cure safely, efficiently, and immediately. As they are designed for use on UV-blocking clear and select colored substrates including translucent variations of blue, purple, gray, white and green, these adhesives offer excellent results in medical applications such as needle bonding and pre-filled syringe assembly. All products fluoresce under black light for easy quality control inspection. These adhesives can also be used for potting applications that require rapid cure to depths of 13 mm.
