UV cure monitoring of paints and adhesives

News International-French

27 Feb 2012

JEC Europe 2012 - Dielectric analysis (DEA) as per ASTM E 2038 and E 2039 standards can be used to measure changes in the dielectric properties of a resin during UV curing. The liquid or pasty resin must be placed in direct contact with two electrodes comprising the dielectric sensor.

The modular concept of the brand-new DEA 288 Epsilon allows for the study of the UV curing behaviour of adhesives, paints, inks and coatings in nearly any application. The lab version, with up to 8 channels, can be used in conjunction with a newly designed furnace for research and development, which has access to a UV lamp triggered via a light guide. The industrial versions are intended for production monitoring and process control, and are designed with up to 16 channels. As an example, the picture shows the slim version with up to two channels. The industrial devices are connected via rugged extension cables and connectors to various types of sensors which are located in moulds, ovens, conveyors or other devices for UV curing.


Reusable tool mount sensors (TMS) in a variety of geometries and temperature/pressure ranges can be applied to moulding processes and dental composites. For paints, inks, adhesives and coatings, various implantable (disposable) comb sensors tailored to a variety of application needs via defined electrode spacing from 1 μm to 115 μm are available.
