Dielectric Analysis - DEA

For investigation of the curing behavior of thermosetting resin systems, composite materials, adhesives and paints, Dielectric Analysis (DEA) in accordance with ASTM E 2038 or E 2039 has stood the test of time. The great advantage of DEA is that it can be employed not only on a laboratory scale, but also in process.
For measurement of the ion conductivity, which is calculated from the dielectric loss factor, or its reciprocal value, the ion viscosity, NETZSCH offers single- and multiple-channel DEA systems, depending on the application, which operate in various measurement and frequency ranges with different types of sensors.

DEA 230 Epsilon – Dielectric Analyzer
There are three different systems in the 230 Epsilon series of Dielectric Cure Monitors: the high-performance, 2-channel DEA 230/2 with the broadest measurement and frequency range, particularly for product development and process optimization, the single-channel DEA 230/1, and the 10-channel DEA 230/10, also suitable for applications in manufacturing.

DEA 231 Epsilon – Dielectric Analyzer
This single-channel measurement system can operate at a high data acquisition rate with a selectable frequency and is therefore ideal for investigation of the crosslinking and curing behavior of fast-curing resin systems, adhesives and paints, e.g. SMC/BMC and UV curing materials.
