Measure the fastest UV curing processes with true inertia-free rheology.
UV curable materials use ultraviolet light or other radiation sources to initiate curing, which allows the formation of permanent bonds without heating. This behavior can be characterized on the ARES-G2 rheometer using the UV Curing Accessory. The accessory uses a light guide and reflecting mirror assembly to transfer UV radiation from a high-pressure Mercury light source to the sample for measurement of the storage and loss moduli during the curing reaction. The accessory includes the upper and lower geometry with removable 20 mm diameter plates, collimator, 5 mm waveguide, and remove radiometer/dosimeter. The system interfaces with a UV light source (Excelitas Omnicure S2000) with wavelengths in the range of 320 to 500 nm. Temperature control up to 150 °C is available using the Advanced Peltier System, APS. Disposable plates are also available for hard UV coatings, which cannot be removed from the plates after curing.
