New Algorithm for Viscometric and Rheologic Measurements Gets US Patent

Jun 18 2008 Read 918 Times

Brookfield’s (USA) Sales Engineer and Rheology Lab Supervisor, David Moonay, Ph.D., has been awarded a U.S. patent for an algorithm he developed that provides “multi-decade viscometric or rheologic measurements of a material undergoing state change.” According to Dr. Moonay, “This algorithm allows us to use Brookfield instruments to collect data on products that gel or cure over a much wider range of viscosity than ever before.” Unfortunately, in the past, the only option for customers was to spend between $30,000 and $50,000 for a
high-end rheometer.
Dr. Moonay developed this solution after talking with customers who complained that their gel timers couldn’t get the viscosity data they needed. Now, Brookfield customers can monitor gelling over a wide viscosity range at a reasonable price. The “Cure Mode Test” is included in Brookfield Rheocalc Software (Version 3.0 and above), and can run on DV-II+Pro Viscometers, DV-III+ and DV-III Ultra Rheometers.
The Cure Mode Test is ideal for adhesives, advanced composites, polymers, and has possible applications in other food, chemical and petroleum products.
