<p dir="ltr">On 25 th -26 th November, 2024, the 21st World Congress of International Union for<br>Surface Finishing (IUSF) was successfully held in Hong Kong. This event was funded<br>by the Innovation and Technology Commission of the Government of the Hong Kong<br>Special Administrative Region, and hosted by IUSF and the Hong Kong Surface<br>Finishing Society (HKSFS). The two-day event brought together many global elites<br>and experts in the surface treatment industry to discuss and share the latest<br>breakthroughs and trends in this important field. This follows the previous congress<br>meeting hosted in Nagoya (Japan), in 2021, which was first delayed and then<br>eventually held on-line because of the Covid19 crisis. It was a delight to meet again<br>in person; in total there were ca. 260 delegates from 9 countries across Asia, India,<br>Europe and the USA. The theme of the meeting was Advanced Materials Finishing;<br>Trends and the Future for Manufacturing, and much of this interest was focused on<br>the increasing interest and demands of sustainability. The meeting also encompassed<br>the interests of 8 distinct national and international materials finishing organisations<br>and so was a globally significant and inclusive event</p>
