Product description CurinScan HT
Innovative solution to characterize and optimize the formulation & the curing of functional film and coatings.
Nowadays, various industries are challenged to provide more competitive and more environment friendly materials. They are constantly on the lookout for innovation, formulation, and reformulation of new materials. Thus, the characterization of these innovative formulations is a key point to control.
Formulaction new development Rheolaser COATING HT or CurinScan HT offers an in-situ, non-invasive and handy characterization way to optimize the formulation (coatings, inks, powders, adhesives, slurries…) and the parameters that can influence its curing and drying (temperature, humidity, substrate, thickness…).
Rheolaser COATING HT enables the monitoring of microstructure changes during the curing and drying process. Based on multispeckle diffusing wave spectroscopy (MS-DWS), it identifies the drying & curing mechanisms (evaporation, packing, hardening) and characteristic times (drying time, cured time). Thanks to laser technology, the measurement is non-invasive and works on any type of substrate.
The optical technology used by the instrument is the multispeckle Diffusing Wave Spectroscopy (MS-DWS). A laser illuminates the coating, the laser photons travel through the coating thickness and interact with the coating’s scatterers (particles, droplets, polymers…). The different optical paths of the photons induce interfered backscattered waves forming an image on the camera composed of bright and dark spots and called speckle image.
The MS-DWS technology allows the study of curing, drying and film forming mechanisms without contact, with high sensitivity, to provide more insight to coating structure evolution.
