Indigo™ PURE Visible Light Curing Adhesives
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.
- Loctite® Indigo™ technology, 3555™ and the Indigo™ CureJet™ LED, were selected for the assembly of irons where deep cure and high adhesion to blue tinted thermoplastic are required.
- The low viscosity Loctite® Indigo™ 3554™ is used for the assembly of purple tinted medical components where biocompatibility compliance is an absolute requirement.
- Loctite® Indigo™ 3556™ is used to assemble high-end sunglasses where speed of cure and cure through blue and grey components are required, and tack-free bonding of the dust cap to cone for speaker assembly.
- Loctite® Indigo™ 3555™ and the Indigo™ CureJet™ LED is specified for prefilled drug syringes where minimal heat exposure and the ability to detect adhesive presence are critical.
