Introducing the RAHN Energy Curing Product Guide 2025!

We are excited to announce the release of our latest Energy Curing Product Guide for 2025. This comprehensive guide showcases our most successfully used and commercially supported products, tailored to meet the diverse needs of industries such as 3D printing, adhesives, coatings on plastics, wood coatings, dental, electronics, and more.

Our product guide highlights the innovative solutions we offer, including epoxy acrylates, urethane acrylates, oligoamines, and polymeric photoinitiators. With a focus on regulatory compliance and sustainability, RAHN ensures that our products adhere to global standards, including EU-REACH, UK-REACH, and China's IECSC.

Explore the guide to discover how our products can enhance your applications.

Study Highlights:

• Matte Surface Generation: Excimer lamps, particularly those operating at 172 nm, are capable of producing deep matting effects with gloss levels between 1 and 30 GU. This is achieved through careful selection of oligomers, monomers, and photoinitiators, as well as control over cure speed, film thickness, and oxygen levels.

• Formulation Screening: RAHN's research identifies key formulation components that influence the matting efficacy of excimer lamps. The report provides detailed screening results for oligomers, monomers, and photoinitiators, offering a valuable starting point for optimizing formulations.
• Soft Touch Coatings: The report explores the potential of excimer lamps in creating soft feel coatings, which are highly sought after in automotive and packaging applications. By changing the settings of the pre-gelling before the excimer lamp combined with the right choice of oligomers and monomers, excimer curing offers a pathway to achieve desirable haptic properties without compromising on scratch and stain resistance.

Key Advantages of Excimer Lamp Technology:

•  High Performance: Deep matte finishes using a minimum of matting powders. This allows formulation of matte varnishes without decreasing coating performance and increasing thixotropy.
• Environmental Benefits: By eliminating the need for solvents and reducing energy consumption, excimer lamp technology supports sustainable manufacturing practices.

Concluding insights:

Our research highlights the transformative potential of excimer lamp technology in the development of UV-curable coatings. The insights in this report, will help formulators achieving ultra-low gloss levels while maintaining the desired application properties.

RAHN invites you to explore the full report for a deeper understanding of how excimer lamps can enhance your coating formulations. For further information or to discuss how these insights can be applied to your specific needs, please contact our team at energycuring@rahn-group.com.
