Reflecting on RadTech US 2024
The RadTech UV&EB Technology Conference, held in Orlando from May 20-22, brought together industry leaders and innovators. Representing Perstorp, Vanessa Maurin and David Engberg share their observations on the latest development advancements in UV+EB technology.
A more optimistic outlook for 2024
Compared to some events last year, RadTech US 2024 showcased a more optimistic view of the future. Industry sentiment suggests a recovering market with stronger demand in segments such as packaging, labels, advertisement, and industrial applications like furniture wood coatings.
Key trends in UV/EB technology
Several key trends emerged during the conference, highlighted in presentations and panel discussions:
1. Shift towards TMP-Free alternatives
The reclassification of TMPTA has spurred interest in alternatives like TMP4EO. There is growing demand in the US and Europe for TMP-free alkoxylates in sensitive applications. Products like TMP4EO (Polyol R3540), TMP3PO (Polyol R3530), and Penta-ethoxylate (Polyol R4640) are gaining traction.
2. Coil coating developments
Environmental regulations are pushing major coil coaters to reduce VOCs and carbon footprints, increasing interest in UV/EB technology. Presentations at RadTech US highlighted the environmental benefits and lifecycle advantages of radiation-cured coatings over traditional thermal cures.
3. Advancements in lithium-ion battery manufacturing
With the lithium-ion battery market projected to exceed $400 billion by 2030, UV/EB technology offers fast curing, chemical resistance, and the ability to produce durable films. Innovations include UV-curable binders and coatings that enhance the performance and sustainability of EV batteries.
4. Continuous development of self-curing resins
Self-curing resins, particularly "Inherently Reactive" urethane acrylate oligomers and reactive acrylic copolymers, are gaining interest. These materials offer low odor and extractables while maintaining essential mechanical properties, addressing regulatory demands, especially in the food and packaging industries.
5. Sustainability-driven industry
Perstorp's contributions
Perstorp made contributions with two notable presentations:
-
Vanessa Maurin's exploration of cationic systems
Vanessa, R&C Application Development Manager Innovation, discussed alternative curing methods (EB and LED) and formulations for cationic photopolymerization, emphasizing low shrinkage and good adhesion. Her presentation explored the potential of cationic technology for new applications such as coil coatings.
- David Engberg presentation on regulatory and sustainability solutions
David, Business Development Director Resins & Coatings, focused on alternative raw materials to TMPTA. David also introduced Pentaspiroglycol (PSG) as a potential safe alternative to BPA. His presentation also covered high functional resins and the traceable mass balance concept for more sustainable building blocks.
RadTech US 2024 highlighted the evolving landscape of UV/EB technology, with a clear shift towards more sustainable and efficient solutions. Perstorp remains committed to advancing these innovations, contributing to a brighter and more sustainable future for the industry.
