Record curing processes – even in process!

The DEA 230 Epsilon has been replaced by the DEA 288 Epsilon 
For the investigation of the curing behavior of thermosetting resin systems, composite materials, adhesives and paints, dielectric analysis (DEA) has stood the test of time because it can be employed not only on a laboratory scale, but also in process. Versatile sensors for almost every application are available for measurement of the ion viscosity.  
The different models of the DEA 230 Epsilon can be connected to the dynamic mechanical analyzer DMA 242 C for simultaneous DMA-DEA analyses. The combination of these complimentary methods provides additional information for complete characterization of the crosslinking behavior of the reactive polymers.  
The high-performance, two-channel DEA 230/2 Epsilon can be equipped with up to two different external interface boxes in order to cover a wide ion viscosity range. It is the only apparatus that can be equipped with the IC (integrated circuit) sensor for low ion conductivity ranges. This chip sensor delivers highly accurate, reproducible loss factor and permittivity results, even at the lowest frequencies.  
Even with the standard instrument, the single-channel DEA 230/1 Epsilon, it is possible to measure the frequency-dependent curing or crosslinking behavior (multi-frequency sweeps) of most thermosets, adhesives and paints.  
The 10-channel DEA 230/10 Epsilon offers the additional capability to employing multiple sensor positions or different sensor types simultaneously, which makes it ideal for process development and production applications.
