New biocompatible adhesive for plastics fluoresces orange 19 December 2019

A new orange fluorescent UV adhesive from Panacol-Elosol GmbH is specially formulated for bonding plastics. Vitralit® 7311 FO is certified according to USP Class VI standards, which makes it the perfect solution for bonding medical devices.

Vitralit® 7311 FO is a low viscosity, transparent acrylic adhesive that cures under UV or visible light. It offers very high bond strength to many plastics including PC, PVC, PMMA or ABS, and also to materials such as glass and stainless steel. Thanks to its very low viscosity and capillary flow characteristics, Vitralit 7311 FO is suited for bonding large surfaces as well as applications with narrow gaps.

Under low intensity black light (365Nm wavelength), Vitralit 7311 FO fluoresces orange. This allows in-line inspection for quality control. The bright fluorescence is highly contrasting with plastics possessing a natural blue fluorescence or colour. Optimum curing results can be achieved with LED curing equipment with a wavelength of 405Nm, especially the Bluepoint LED Eco Point Source Unit from Hönle. The Bluepoint LED Eco can be equipped with both wavelengths, serving both processes. Thanks to modern photo initiators Vitralit 7311 FO can be cured – especially in high volume production – within seconds.

Once cured, Vitralit 7311 FO is humidity and alcohol resistant. It has also been tested and certified according to USP Class VI standards. The product is compatible to common sterilisation processes such as autoclaving, gamma radiation, E-Beam or ETO and is well suited for use in the assembly of disposable medical devices.
