EVAPORATIVE DYNAMIC OSCILLATION (EDOT)
Evaporative Dynamic Oscillation (EDOT) is an exciting and novel methodology that allows evaluation of evolution of rheological properties of polymers/coatings as the sample dries and cures as a function of time and/or temperature.
EDOT quantitatively characterizes the dry and cure profile of paints, coatings, and adhesives throughout the entire dry and cure regime, from application through complete cure at essentially any time/temperature profile, including if desired, aging effects. Further, EDOT allows one the ability to evaluate film properties in-situ such as modulus, glass transition temperature, stiffness, shrinkage, creep, and compliance, for example. Using EDOT, a scientist may quantitatively assess the impact of polymer composition, molecular weight, formulation constituents, as well as pigmentation effects on coating properties. EDOT is a powerful methodology for characterizing neat polymer properties as well, even if solvent is originally present in the sample.
