New potting compound for piezoceramics

Eurobond Adhesives has recently expanded its range of dual-curing acrylic adhesives with the introduction of Vitralit^® UD 8052 F. This new UV curing adhesive, from Panacol, has been developed for piezo actuators and sensors and is said to possess a particularly high tear resistance for bonding ceramics and plastics.

Vitralit^® UD 8052 F is a low viscosity, one-component UV curable adhesive. Eurobond says that it is jettable, transparent, and fluoresces under UV light. Customised versions with different colours are available to facilitate improved process control. Its jet dispense capability is said to make high UPH (units per hour) values achievable, which is why Vitralit^® UD 8052 F has proved to be a popular choice for consumer electronics applications, says the company.

Vitralit^® UD 8052 F 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 polymerizes reliably into a flexible potting and glob top compound.

Its high tear resistance after curing has been optimised for bonding ceramic components to plastic, compensating for the different expansion coefficients of the bonded materials. Thus Vitralit^® UD 8052 F is said to be particularly suitable as a protective coating as well as for applications subject to tensile and compressive stresses. As a potting compound, it features a low halogen content, is flexible and offers protection against corrosion and other environmental influences.
