Are you a BSc or MSc student in Chemistry/Materials Science and looking for a graduation assignment? Are you excited to play a key role in improving the sustainability of our UVgel™ technology? We are looking for you!
Background
CPP’s UVgel™ technology is based on a solvent-free ink system formulated with acrylate monomers that polymerize and form a solid layer upon exposure to UV light. The UV-gel™ inks are designed as low-viscosity liquids at jetting temperature, allowing droplet formation. When the ink hits the substrate, which is held at a lower temperature, the gel solidifies, preventing coalescence of nearby ink droplets allowing for unparalleled print accuracy and print quality. Once deposited, the ink droplets are exposed to controlled UV-light where photoinitiators absorb energy and generate reactive radicals that rapidly form a polymer network resulting in a solid film. This curing process creates a highly durable, scratch-resistant layer with excellent adhesion to a range of media. Because the system is 100% solids and free of water or solvents, UVgel™ technology is often considered as free of emissions or volatile organic compounds (VOCs). However, small acrylate components can still volatilize if they remain unreacted, leading to undesirable emissions from printed materials. The Sustainable UVgel™ group at CPP conducts early-phase research to enhance the sustainability of this technology and explores strategies to reduce emissions.
Your assignment
We aim to investigate how the curing behavior of acrylate systems and the conversion of functional acrylates influence post-curing emissions in UVgel™ prints. The project will involve formulating model inks, performing acrylate conversion analysis, and preparing samples for emission and migration testing. Your work will contribute to understanding the link between polymerization efficiency and residual monomer volatility, ultimately helping to make UVgel™ technology safer and more sustainable!
Your profile
We expect an understanding of chemistry, preferably acrylate chemistry, (free radical) polymerization through UV photoinitiation and curing kinetics.
In short:
• You are a student (MSc/BSc) in the field of Chemistry, Chemical Engineering, Materials Science or related

• You are able to design and perform your experiments (making ink formulations, testing curing kinetics using FT-IR, preparing samples for emission and migration tests)
• You enjoy exploring new ideas and can translate them into practical experimental approaches
• You are able to process, visualize and interpret experimental data
What’s in it for you?
• A challenging assignment in early phase research (Technology Development)
• Skilled coaching
• Internship/ Graduation compensation of €500,- per month
• Travel cost compensation if you don’t have an ‘OV-weekcard’
• The possibility to network with professionals inside and outside your field of expertise, thanks to our diversity of disciplines which you will work with
