New dual-curing potting compound for piezoceramics
Panacol is expanding its portfolio of dual-curing acrylic adhesives with the introduction of Vitralit® UD 8052 F. This material was developed for piezo actuators and sensors. It possesses a particularly high tear resistance for bonding ceramics and plastics.
Vitralit® UD 8052 F is a low viscosity, one-component UV curable adhesive. It is jettable, transparent, and fluoresces under UV light. Customized versions with different colors are available to facilitate improved process control. Its jet dispense capability makes high UPH (units per hour) values achievable, which is why Vitralit® UD 8052 F is the perfect choice for consumer electronics applications.
This potting compound can be cured in just a few seconds with UV light (320nm - 390nm) or visible light (405nm). The fluorescing adhesive allows in-line process control with short-wave light for maximum productivity. In areas that cannot be reached by light, Vitralit® UD 8052 F post cures with atmospheric moisture, and thus polymerizes reliably into a flexible potting and glob top compound.
Its high tear resistance after curing has been optimized for bonding ceramic components to plastic, compensating for the different expansion coefficients of the bonded materials. Thus Vitralit® UD 8052 F is particularly suitable as a protective coating and for applications subject to tensile and compressive stresses. As a potting compound, it features a low halogen content, it is flexible and offers protection against corrosion and other environmental influences.

Panacol and Hönle develop new system solution for filament winding processes
With the newly developed Vitralit® UD 1405 adhesive, Panacol has created an innovative adhesive system for fibre and filament winding. For high efficiency, Vitralit® UD 1405 can be applied during the winding process and immediately cured with high intensity LED curing systems from Dr. Hönle AG. This innovative winding process is extremely space and time-saving, and can produce significant processing cost savings.
Vitralit® UD 1405 can be used to wrap components such as hybrid rotor shafts for electric motors and high-voltage surge arresters. The adhesive-coated fibre-reinforced windings can be then be quickly cured with UV/visible light. This adhesive and curing system is ideal for Carbon or Glass Fibre filament winding associated with Carbon Fibre Reinforced Polymer (CFRP) or Glass Fibre Reinforced Polymer (GFRP) manufacturing processes.
Panacol’s Vitralit® UD 1405 is a transparent, solvent-free, one-component epoxy. Due to its low viscosity, Vitralit® UD 1405 has very good wetting properties. It can be cured in seconds by irradiation with UV (365nm) or Visible (405nm) light wavelengths. Depending on the fibre material and the wavelength used, layer thicknesses of several millimetres can be achieved exclusively by UV/Visible light curing. This epoxy can also be thermally cured after UV exposure to ensure that a complete cure is secured in areas shadowed from the UV light. For example, fibres or filaments can first be pulled through an adhesive bath, then wound onto the rotor or respective cylinder, and cured with UV or visible light. A secondary thermal cure will ensure that the layers of coated windings below the surface become fully cured.
For the most efficient UV curing system for fibre and filament winding processes, the LED Powerline AC/IC 820 HP from UV specialist Hönle is the perfect choice. With intensities of up to 16,000 mW/cm², this LED system ensures very fast curing. Its light emission window is available in two standard sizes, 82 mm x 20 mm and 122 mm x 20 mm, which can be extended without gaps by stringing together multiple modules. When developing the LED Powerline AC/IC 820 HP, special attention was paid to a slim design. This makes it ideal for use where space is at a premium, such as automated winding equipment.
The powerful LED Powerline AC/IC 820 HP can be powered and controlled using the optionally available LED powerdrive IC as a plug&play solution, or by using a customer supplied external power supply and PLC. This makes the LED Powerline an ideal solution for integrating high power LED curing systems into automated assembly processes.
After curing, Vitralit® UD 1405 is electrically insulating, shows minimal shrinkage and remains resistant at temperatures from -40° to 180°C. A glass transition temperature of over 130°C ensures reliable performance even under dynamic load at elevated temperatures.

Adhesives for Cell Contacting Systems and Battery Packs
Panacol has developed specially formulated UV adhesives that protect welded joints on cell contacting systems and battery packs of electric cars from corrosion. The flexible adhesives enable vibration-resistant connections and have a low ion content.
High-performance cell contacting systems (CCS), which combine individual lithium-ion battery cells for hybrid and electric vehicles to form battery packs, are often connected by welded strands or wires. To protect these welded joints from corrosion, Panacol has developed special low-ion UV adhesives that are applied as protective coatings. These adhesives provide additional mechanical support when subjected to vibrations and can compensate for thermal expansion of the different materials.
UV-curing adhesives Vitralit® UV 2113 and Vitralit® UV 2114 are characterized by very high adhesion to many materials and meet the requirements of the automotive industry in terms of media and temperature resistance. The rheological properties of both Vitralit® UV 2113 and Vitralit® UV 2114 can be adapted to individual customer requirements. Fluorescent adhesive variations for optical process control are also available.
In just a few seconds, these adhesives can be cured with light in the UVA or visible range. Both gas discharge lamps and LED spot systems can be used for curing. Perfectly matched to Panacol adhesives are the UV and LED UV curing systems from Dr. Hönle, for example the high-intensity LED Powerline AC/IC HP.
For complex CCS geometries with shadowed areas, dual curing Vitralit® UD 8050 is the perfect choice. After UV irradiation, this ion-pure acrylate adhesive post-cures in the shadowed areas by reacting with humidity in the air.
