DRYING CURING & FILM FORMATION ANALYZER
The CurinScan Expert and CurinScan Classic Turbiscan allow the monitoring of curing and drying process. Thanks to the Nanoscale Mobility Analysis (NMA), it identifies the drying and curing mechanisms (evaporation, packing, and hardening) and the characteristic times (open time, dry-surface, dry through, etc.) of any film forming coating, including paints, inks, adhesives, and varnishes.

How does the CurinScan work?
A laser beam is scattered by moving particles in a specific pattern. A Camera monitors the image of the resulting interfering wave (speckle). As the mobility of the particles changes during drying the pattern fluctuates. Pixel by pixel analysis of the speckle allows to plot decorrelation curve as a function of characteristic time and directly correlates to particle motion speed.
The decorrelation curve can be analyzed using different physical models allowing to determine multiple structure properties
In drying experiments (using Curinscan), the Fluidity Factor can be monitored over time. It is inversely proportional to characteristic decorrelation time and it provides information about sample fluidity. It allows monitoring of drying and film formation processes. Drying mechanisms (evaporation, packing, particle deformation…) can be detected and a unique signature profile of coating drying can be obtained.
What is diffusing wave spectroscopy (MS-DWS )
Multi Speckle Diffusing Wave Spectroscopy (MS-DWS) monitors the structural properties of a material.
The measurement of the Brownian motion of the particles using the MS-DWS optical method allows determining the structure-related properties of the sample. MS-DWS can be used with different types of sample forms. In a bulk sample, viscoelastic properties related to gel formation and network structure evolution can be studied with time and temperature. When a thin film layer is applied, coating drying and film formation without any contact with the sample can be characterized. In relation to fast temperature ramps or cycles, the dynamics at the microstructure scale provide information about phase transitions and structure reorganization (crystallization, melting…). This optical method is highly sensitive to the smallest structure change.
