A practical guide to calm beads, clean process windows and films that behave By Guri Dhillon, Founder, XRD Nano Ltd, United Kingdom Abstract Choosing a coating method for UV resins is a balance of viscosity, coat weight, web speed and cure strategy. This selector links viscosity at 25 °C to the methods that naturally work, the coat weights they tend to deliver, and the speeds they tolerate. It then offers simple rules for common nano imprint and micro optics tasks, with a few

There is a quiet document at the bottom of the website. It does not ask for attention. It simply tells the truth. It is the technical data sheet. Trade fairs love ambition. Banners promise revolutions by Tuesday. Videos glide in slow motion. A graph climbs like a ski jump while the axes hide. In the corner sits the data sheet. It clears its throat. It has numbers. It has test methods. It has footnotes. Truth is awkward because it insists on context. A modulus without temperat

A reflection on precision, chemistry and the quiet art of control in polymer replication By Guri Dhillon Founder, XRD Nano Ltd, United Kingdom Abstract Shrinkage is one of the oldest and most persistent challenges in UV curable resin technology. This article looks at why it happens, how curing wavelength influences dimensional stability, and what can be done in formulation and process control to achieve replication accuracy at the sub-micron level. Introduction The story of U

A reflection by Guri Dhillon, Founder, XRD Nano Ltd (UK) Most industries dream of solving their greatest problem. Ours quietly hopes it never does. Every year, billions are spent fighting fakes, yet the problem refuses to disappear. We design clever holograms, smarter inks, traceable codes, digital twins and new databases, while the counterfeiters continue to keep pace with astonishing agility. Perhaps this is not failure at all but balance, an unspoken understanding that kee
