New adhesive introduced 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 and it possesses a particularly high tear resistance for bonding ceramics and plastics, said the company.
Vitralit UD 8052 F is a low viscosity, one-component UV curable adhesive. 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 makes high UPH (units per hour) values achievable, which is why this solution is the perfect choice for consumer electronics applications, as per the statement.
This potting compound can be cured in just a few seconds with UV light (320nm – 390nm) or visible light (405nm), according to the press release. 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 polymerises reliably into a flexible potting and glob top compound.
Its high tear resistance after curing is said to have been optimised 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 the company says it offers protection against corrosion and other environmental influences.
