Panacol has expanded its portfolio of dual-curing acrylic adhesives with the introduction of Vitralit® UD 8052 F, which was developed for piezo actuators and sensors. According to the company, the new adhesive 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 units-per-hour values achievable, making Vitralit UD 8052 F an ideal choice for consumer electronics applications.

According to Panacol, this potting compound can be cured in just a few seconds with UV light (320-390 nm) or visible light (405 nm). 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.
