The STRESSTECH HR rheometer is equipped with a UV Cure Monitoring Accessory and proprietary Fast Oscillation Data Acquisition Software. The instrument utilizes the integrated light triggering capability and data collection rates greater than 100 points/s, along with combined shrinkage measurements for monitoring the real-time cure profiling of light activated DNS materials. The information is critical to optimizing formulations and processing conditions, and predicting product performance and acceptance. In addition the rheometer utilizes Fast Oscillation Data Analysis which allows for real time UV cure profiling and shrinkage determination by providing the ability to capture the rapid, transient changes in the material.
