Paint and Coating Pigments

RSS

This article highlights the challenges of lead replacement and shows how modern pigment developments provide an alternative to lead chromate in coatings applications, and how the performance of lead-free formulations can be improved.

Scientists and artists alike have been invested in isolating pigments from nature and developing novel pigment technologies for coatings and other industries.

As the TiO2 market strengthens post-pandemic, TiO2 consumers in North America will continue to be faced with the dilemma of how best to find reductions in TiO2 costs.

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.
