Available through Techsil, Panacol’s Vitralit UD 1405 is a transparent, solvent-free, one-component epoxy. With it's low viscosity, the epoxy provides very good wetting properties. It can be cured in seconds by irradiation with UV (365nm) or Visible (405nm) light wavelengths. Subject to the fibre material and the wavelength employed, layer thicknesses of several millimetres can be accomplished exclusively by UV/Visible light curing. The epoxy can also be thermally cured after UV exposure to assure that a complete cure is confirmed in areas shadowed from the UV light. A secondary thermal cure will confirm that the layers of coated windings below the surface become completely cured.
After curing, the epoxy is electrically insulating, exhibits minimal shrinkage and stays resistant at temperatures from -40C to 180C. A glass transition temperature of over 130C provides reliable performance even under dynamic load at raised temperatures.
This adhesive and curing system is excellent for Carbon or Glass Fibre filament winding associated with CFRP or GFRP manufacturing processes.
The epoxy can be utilised to wrap components such as hybrid rotor shafts for electric motors and high-voltage surge arresters. The adhesive-coated fibre-reinforced windings can then be swiftly cured with UV/visible light. This innovative winding process is particularly space and time-saving and can deliver significant processing cost savings.
