Heraeus Noblelight opens LED curing test facility
Response to growing demand in industry
Heraeus Noblelight, a US-based arm of the German precious metals firm which is active in speciality light source production, has announced the establishment of its UV LED curing testing facility. The company said that it had done this in response to the need of formulators, OEMs and end users “to evaluate cure quality using LED technology in a cost effective manner” as UV LEDs become increasingly popular in the curing of inks, coatings and adhesives.
The company has also formed a new Optoelectronics division to develop customer-optimised LED solutions in the near UV spectrum. This division will be able to work with customers in the facility.
LED curing is said to offers “significant advantages” such as low power consumption, low heating of sensitive substrates and long lifetime. UV LEDs are single wavelength devices and success in curing them depends on formulators selecting and testing photo-initiator packages optimised for the LED wavelength. Parameters such as intensity, dose, working distance and peak wavelength emission all have an impact on curing and the facility is designed to help with that,
