Using Malvern’s Kinexus Rotational Rheometer with UV Accessory to Determine Cure Profile and Post-Cure Shrinkage of Photopolymers
1 September 2015

Photo-curing is a relatively rapid process compared to thermal curing and therefore the process can be used for selective curing using high energy light sources, making the process suitable for printing circuit boards and fabricating microchips. This application note shows how in-situ characterization of rheological properties of UV curable materials can be performed on a Kinexus rotational rheometer with UV curing accessory. The Kinexus rheometer design has been underpinned with the market-defining strengths of the previous generation Bohlin rheometers, coupled with advances in shear and vertical (axial) testing, to deliver a rotational rheometer platform with unprecedented dual-action capabilities.
