New biocompatible plastics adhesive which fluoresces orange

15-01-2020 | Techsil | Subs & Systems

Techsil has introduced a new orange, fluorescing, UV curing adhesive created for bonding plastics. Produced by Panacol, Vitralit 7311 FO is certified according to USP Class VI standards. An excellent adhesive for medical devices, it can also be employed in electronics, optics and general assembly applications.


The adhesive is a transparent acrylic adhesive that cures under UV or visible light. It provides extremely high bond strength to many plastics comprising PC, PVC, PMMA or ABS, and also glass and stainless steel. With low viscosity and capillary flow characteristics, the adhesive can bond large surfaces and applications with narrow gaps.


Under low-intensity black light (365nm wavelength), the adhesive fluoresces orange. This enables in-line inspection for quality control. The bright orange contrasts with plastics holding a natural blue fluorescence or colour. Due to modern photo initiators, the adhesives cure within seconds which works well in high volume production.


Once cured, the adhesive is humidity and alcohol resistant. The adhesive has been tested and certified according to USP Class VI standards. The product is compatible with common sterilisation processes like gamma radiation, autoclaving, E-Beam or ETO and ideal for employment in the assembly of disposable medical devices.
