Editor’s Note

A Digital Age for Inks and Coatings Industries

— Prof. Long Lin

Readers of CCJ will be in for another treat when reading through this issue, which shares some exciting technological advancements achieved by globally leading players. I felt spoilt when reading through such an excellent assortment of technical papers that cover a very large portion of the spectrum of my technical interests.

 

Market Insight

The Global Paint and Coatings Industry: Five-year Perspective

— George R. Pilcher, The ChemQuest Group, Inc., USA

Like it or not, we live in a global economy, and even though the paint and coatings industry still has many regional and local elements in its make-up, it is strongly impacted by global economic conditions, because there is a strong correlation between GDP per capita and paint and coatings consumption per capita.

 

Protective Coatings

Copper-Containing Glass Ceramic with High Antimicrobial Efficacy

— Timothy M. Gross, Joydeep Lahiri, Avantika Golas, Jian Luo, Florence Verrier, Jackie L. Kurzejewski, David E. Baker, Jie Wang, Paul F. Novak & Michael J. Snyder, Corning Incorporated, USA

Hospital acquired infections (HAIs) and the emergence of antibiotic resistant strains are major threats to human health. Copper is well known for its high antimicrobial efficacy, including the ability to kill superbugs and the notorious ESKAPE group of pathogens. We sought a material that maintains the antimicrobial efficacy of copper while minimizing the downsides — cost, appearance and metallic properties — that limit application.

 

Digitalisation

Digital Assistant: A New Technology for the Coatings Industry

— Evonik Industries AG

At home, in the car, and while shopping, voice-controlled digital assistants have become a part of daily life. In the future, they will also make lab work easier. The first such assistant to specifically help scientists in the coatings industry is named COATINO™.

 

Case Study

Creating Sustainable Buildings in the Middle East

— Mohammed Sanaobar, Regional Technical Director, Wacker Chemicals Middle East

The United Arab Emirates (UAE) has the second-largest economy in the Arab world. Cities such as Dubai have become global business hubs, attracting expatriates from all over the world. The growing population comes with an increasing demand for housing and infrastructure as well as energy and water. The WACKER chemical group and Dubai Central Laboratories joined forces to set construction standards for sustainable, energy-efficient buildings in the region.

 

Measurement and Testing

Wide Shear Coating Viscosity Analysis Utilising a Microfluidic Rheometer

— Thanina Amiar, Hubert Ranchon, Giovannni Brambilla, Formulaction, France; Ellen He, LDS Technology Ltd., P.R. China

For surface coatings, optimising the viscosity is a key to obtaining satisfying results. The shear rate encountered when formulations are sprayed or jetted may be above . Standard viscometers and rheometers may not be able to accurately measure their representative viscosities. In order to mitigate that limitation, a new characterization strategy based on microfluidics has been developed. In this article, limitations of classical viscosity characterisation are briefly reviewed and the description of a novel microfluidic viscometer is given. PTFE coatings and ceramics inkjet characterisation over wide range of shear rates is then described.

 

Grinding and Dispersion Technology

New Pre-dispersion Milling Process Delivers 128% Increase in Efficiency for Colour Dispersions

— Steffen Pilotek, Buhler, Inc., USA; Verena Mühlberger, Bühler AG, Switzerland

A new advanced pre-dispersion process for colour coatings is delivering up to 128% increase in process efficiency whilst improving product quality and reducing cycle times. Could this be a game-changer for the coatings industry?
