With Vitralit® UD 8050 MV F, Panacol has developed another adhesive system certified for use in the medical industry. What is special about this adhesive is that in addition to its primary curing - UV crosslinking - this adhesive also offers secondary moisture post-curing. This means that components in medical devices can be cured in a process-safe manner and without thermal influence, even if shadow zones are present in component cavities.

Unlike moisture curing cyanoacrylates, Vitralit® UD 8050 MV F can be processed reliably because its primary curing is based on UV crosslinking. Moisture in the air does not cause the adhesive to cure while still in the dispensing needle. This offers the user a wide process window. In addition, there are no blooming of frosting effects on the plastics, which can occur when using cyanoacrylates.

Vitralit® UD 8050 MV F is certified according to ISO 10993-5/-10/-23 biocompatibility testing. Since the dual-curing adhesive exhibits high adhesion to many different substrates, it is the optimal solution for a wide variety of bonding applications. As shown in Fig. 1, the UV acrylate is ideally suited for fixing batteries on glucose sensors (corner bonding). It can also be used as a glob top for protecting SMD components. The adhesive will cure reliably and stress-free, even in the shadow areas under the bonding wires. When used for structural bonding, Vitralit® 8050 MV F can be applied between transparent and non-transparent substrates. Bonding is accomplished in seconds with UV/visible light. Shadowed areas will subsequently post-cure with moisture. Due to the high ionic purity of Vitralit® 8050 MV F, the adhesive can be processed on metallized surfaces without hesitation. For optical quality control of the bond, Vitralit® 8050 MV F is additionally equipped with fluorescent markers that can be excited with short-wave light.
