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.
