Light curable adhesive with multiple viscosity options

Panacol has introduced a newly developed light curing acrylate adhesive, specially formulated for bonding plastics, metals and glass, and available in three different viscosities – a low-viscosity, medium flow and a non-flowing gel.

The appropriate viscosity can be chosen depending on the application.

Low Viscosity – Vitralit 7311

Vitralit 7311 is extremely low viscosity and thus a suitable choice for very tight bond gaps. Its low viscosity enables it to wick into pre-assembled parts and spread over large bonding areas.

Medium Viscosity – Vitralit 7311 T

Vitralit 7311 T is a mid-range viscosity version and gives clear bond lines that allow for visually tidy applications and easy convenient dispensing.

High Viscosity - Vitralit 7311 Gel

Vitralit 7311 Gel features high viscosity, non-flowing properties for gap filling or for when controlling adhesive flow is critical, such as uneven or vertical surfaces.

All three variations of Vitralit 7311 provide excellent adhesion to plastics such as polycarbonate, PVC, ABS and PMMA, as well as to metal and glass. Vitralit 7311 is transparent and non-yellowing. It is resistant to alcohols and humidity. Once cured, the adhesive will be viscoplastic. For use in medical applications, Vitralit 7311 is currently being tested according to USP Class VI and DIN ISO 10993-4/-5 standards.

Vitralit 7311 cures in seconds with ultraviolet or visible light. For excellent curing results, high-intensity LEDs at 405nm wavelength are recommended. This wavelength also permits the bonding of materials such as polycarbonate, which block UV rays. Vitralitv7311, as an example, can be utiliaed for needle bonding in medical device manufacturing. Cured with a Bluepoint LED eco light source from UV lamp manufacturer Hoenle, Vitralit 7311 achieves high bond strength in less than a second, providing reliable and durable bonds.
