New UV anaerobic adhesive from Panacol
Panacol has developed Vitralit UD 4292 F, a new dual-curing adhesive that cures primarily by UV light and secondarily anaerobically in shaded areas. The special feature of the adhesive system is the high glass transition range of over 130°C with optimum curing parameters.
With Vitralit UD 4292 F, Panacol has further developed its portfolio of dual-curing adhesive systems in response to the growing market demand for UV anaerobic adhesive systems for structural bonding and sealing in automotive and electronics applications. Vitralit UD 4292 F is a transparent acrylic system that can be cured in just a few seconds with light in the UVA or visual range. Dr. Hönle's LED spot devices, whose wavelengths are specifically aligned with the adhesive's photoinitiators, have proven particularly suitable for curing. After UV curing in seconds, the adhesive polymerizes anaerobically in shadow areas. Post-curing can be accelerated by adding heat or by using an activator. With optimally selected curing parameters and subsequent polymerization by metal ions in the absence of oxygen, Vitralit UD 4292 F ensures high adhesion to metals.
According to the company, these properties make Vitralit UD 4292 F particularly suitable for a wide variety of bonding applications in the manufacture of electric motors, such as structural bonding of ball bearings or shaft-hub connections on the rotor and stator. A special feature of this new adhesive development is the high glass transition temperature of over 130°C, which ensures that the adhesive system retains its bond strength even under the influence of temperature and dynamic stress. This UV anaerobic adhesive system therefore meets the high requirements of the drive sector in particular. For visual control in manufacturing processes, Vitralit UD 4292 F has been provided with a fluorescent marker that fluoresces blue when excited by black light, making it visible even in thin gaps.
