Editor’s Note

Best Wishes for Coatings Industry

— Prof. Long Lin

Readers who concern themselves with worldwide news will realise that as I pen this editorial, the UK is going through an extremely painful period of time. Indeed, for people living in the UK, it is hardly possible to have their minds divorced from the events surrounding Brexit.

 

Market Insight

South America Coatings: Beyond Slow Recovery

— Francisco Z. Rácz & Washington T. Yamaga, Rácz, Yamaga & Associates, Brasil

Challenges for the coatings industry and for raw materials suppliers in South America are well known and are not a matter of concern. The global and most of local industries are ready to fulfill technology needs of a growing market. The supply chain and the industry still have to provide improved services to this market.

 

China Coatings Market Keeps Upgrading in 2019

— Prof. Glenn Hu, South China University of Technology, Guangzhou, China

In 2018, China’s economy maintained a steady growth of 6.6%, and the GDP jumped to a new level of more than RMB 9 trillion. Providing important supporting materials for the national economy, the coatings industry has maintained a stable growth trend under comprehensive influence of the development of domestic real estate industry, furniture industry, automobile industry and petrochemical industry.

 

Wood Coatings

China’s Industrial Waterborne Wood Coatings Market Study

— Waterborne Coatings Platform (WBCP) secretariat

In 2018, wood furniture output was 310 mil pieces, decreased by 11% YOY, of which domestic sales volume accounts for 60-70%. The domestic wood furniture is affected by real estate and is expected to decline further in the future. The export of wood furniture is affected by Sino-US trade war and anti-dumping, as result, furniture manufacturers are moving to Southeast Asia.

 

Protective Coatings

New Generation Corrosion Control Coating Technology with High Crosslink Density and Nano-Reactive Materials

— Atman Fozdar, Ronald Lewarchik, Raviteja Kommineni, Chemical Dynamics LLC, USA

Our research has led to the development of single component polymeric penetrant which can be applied with or without surface preparation over clean or lightly corroded steel/aluminium (no sand blasting or chemical treatment needed). The coating contains unique Nano-sized reactive materials which first penetrate the rust and scale to its morphological depth and then migrate to the non-corroded metal surface.

 

Additives

Indispensable Surface Additives Effect VS Chemistry

— Dr. Majdi Al-Masri, BYK-Chemie GmbH, Germany; Leiping Fan, BYK Additives (Shanghai) Co. Ltd, Shanghai, P.R. China

Since prehistoric cave paintings, coatings have developed slowly from artistry to technology. Decoration used to be the main purpose of coatings. The protective function of coatings, with some exceptions in applications such as wood and leather, emerged after the Industrial Revolution.

 

Functional Matting Agent for Water-Based Clear Coats

— Siegfried Heckl, Area Sales Manager, Author: Bodo Essen, Hubert Oggermüller, HOFFMANN MINERAL GmbH, Germany

Dispersion-based clear coats are becoming increasingly popular as efficient, versatile, and environmentally friendly coating materials with low VOC emissions. The process of matting these coatings while still maintaining both excellent film appearance and excellent resistance properties is sometimes difficult, especially when using binder emulsions with higher minimum film formation temperature and glass transition temperature. Furthermore, when it comes to dealing with traditional matting agents, there are significant disadvantages presented by their form, which are mostly powder-based.

 

Pigments

Characterisation of Interference Pigments

— Werner Rudolf Cramer, Germany

Pigments manipulate the incoming light and partially reflect it. These reflected components trigger a colour stimulus in the human eye, which is transformed into a colour by the brain. This manipulation of light is described by physics, the transformation into a colour by physiology. How the manipulation really happens, we cannot recognise. For example, if a red and a yellow pigment are mixed to give orange, then this orange may look the same as an orange pigment. However, the blend’s reflectance curve has a typical saddle that lacks in the orange pigment.
