The coatings industry will play a major role in our near future’s sustainable way of life. Accordingly, new generations of pigments for coatings must provide more than color for surfaces. Not only must they enable the aesthetic visual appearance through colors and effects, they are also required to contribute to a comfortable, safe, and sustainable future. This article reviews a new generation of coatings and color materials supporting the “Cool City” initiative showcased across the United States.
Following an extensive R&D program that demonstrated full proof of concept for a novel platform process for production of a wide range of inorganic powders based on 27 metals, this article covers the new technology that is now covered by five international patents and patent applications.
Special measurement techniques, sample preparation, and attention to detail are prerequisites for the measurement of high-gloss, deep-black coatings. In this article, one company explores which measurement geometry is best suited for each range of color depths.
The effects of different particle sizes, forms, and loading levels of carbon black on colorimetric properties in powder coating resin systems are investigated.
As a stabilizer and secondary rheology modifier, colloidal MCC provided minimum viscosity to waterborne coating systems at low use level while significantly improving in-can shelf stability and color-tinting ability.
This article discusses some of the terms and calculations related to pigments used in coatings, including oil absorption/surface area; pigment volume concentration; and pigment to binder ratio.
Each pigment manufacturer optimizes particle size for the specific properties for that pigment grade. Hiding, tint strength, photo stability, viscosity and surfactant/resin demand are all affected differently by particle size.
The TiO2 industry continues to change through unusual global economic conditions. The uncommon response of global producers is changing the short- and long-term dynamics of the industry.
A main theme at the ACS was sustainability and the circular economy. This article provides a snapshot of just some of the technology that PCI learned about.
