Measurement Principle: Multi-Speckle Diffusing Wave Spectroscopy (MS-DWS) and patented Adaptive Speckle Image Interferometry (A.S.I.I.) processing technology.  
Using the microrheology measurement principle of MS-DWS technology, the movement of particles during film formation is detected. With the aid of A.S.I.I. data processing technology, the motion of particles from very fast to very slow is recorded. The curve of the flow factor over time reflects this dynamic change process of particles.
The unique patented A.S.I.I. (Adaptive Speckle Image Interferometry) processing technology displays the change of the flow factor over time during the drying process in real-time, providing extensive information:
● Microstructural changes (particle rearrangement, particle deformation, curing process)
● Drying times (Open Time, Touch Time, Dry Time)
● Curing time
Rheolaser Coating can be configured with multiple detection heads, allowing multiple experiments to be conducted simultaneously.
● Depending on the number of detection heads, it is divided into: Basic type and Standard type.

● A commercial instrument specifically designed to measure the dynamic drying process of coatings.  
● An instrument that applies rheological theory to detect the dynamic drying process of coatings.
● A non-destructive testing instrument.
● A tool for studying the mechanism of film formation.
● A single test can provide information on coating water content and adhesion.

Application areas include various types of coatings, inks, cosmetics, adhesives, concrete, battery slurries, solar panel coatings, etc. It is suitable for measurement on any type of substrate: metal, glass, plastic; concrete, wood, paper.
