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.
