Our Series 9 of OCCA Weekly Webinars continues with "Improving the performance of UV curable formulations by addition of polythiols" presented by Tom Beyersdorff of Bruno Bock. The webinar will take place via Zoom on Wednesday 22 February at 2:30pm. This webinar is free to attend, simply register below and you'll receive further details & joining instructions in due course.
Abstract:
The addition of Thiocure polythiols as co-monomers to UV curable formulations provides several benefits such as reduction of oxygen inhibition during cure, the possibility to cure very thin and very thick layers or the possibility to cure highly pigmented or filled systems. In addition, Thiocure-Acrylate networks typically have a much more homogenous structure and show reduced brittleness and improved impact resistance compared to pure acrylic networks.
All of these benefits can be explained by a change in the curing mechanism which is induced by the addition of Thiocure polythiols to the formulation.
In this webinar the change in curing mechanism will be discussed in more detail in order to understand how the change in mechanism leads to the above mentioned benefits.In addition the results from comparative tests with amine synergists at different wave length, photoinitiator concentrations and film thicknesses will be provided. Furthermore a brief overview on the influence of Thiocure products on the mechanical properties of the cured film will be presented. Finally formulation guidelines for using Thiocure products in UV curable formulations will be provided.
