Paint and Coating Pigments

An overview of types of pigments, the pigment industry landscape, challenges with TiO2 production and next-gen pigment technologies.

RAW Paints has developed a patented white pigment formula to replace TiO2 in white paints for use on interior and exterior surfaces, in one formula.

TiPMC believes that the details support that the worst is over for TiO2 producers and that the industry is poised for a strong recovery.

Holger Hüppeler, Head of LANXESS' business unit Inor¬ganic Pigments, discusses the company's challenges and successes during the COVID-19 pandemic, as well as its outlook for the market and business strategies moving forward.

As COVID-19 spread outside China, TiO2 sales were impacted. TiPMC provides some insight, along with a view of what signs will signal an industry recovery.

During both the production process at the TiO2 producer and the manufacturing process of paints, coatings and composite materials, avoiding the coagulation and agglomeration of the TiO2 dispersion is important. Surface chemistry of the TiO2 dispersion can be controlled during the measurement of Electrokinetic Sonic Amplitude (ESA) by regulating the pH value, e.g. for avoiding flocculation of dispersion.

These color boost and compatibilizer post-addition additives are designed to improve color performance and reduce or elimi¬nate incompatibility, allowing paint formulators to overcome most of the challenges associated with VOC-free universal tinting systems.

Ochre, one of Earth's oldest naturally occurring materials, was often used as a vivid red paint in ancient rock art known as pictographs across the world. Despite its broad use throughout human history and a modern focus on how the artistic symbolism is interpreted, little research exists on the paint itself and how it was produced.

Currently there are two types of advanced appearance measurement instruments avail¬able on the market capable of determining radiometric and texture information of effect color shades at various directional and quasi-diffuse measurement geometries.

Microfibrillated cellulose (MFC) is a multi-functional additive for coatings, adhesives and sealants, with a pronounced effect in improving rheology, stabilization and surface properties.
