Innovations in pigment chemistry to address regulatory, performance and sustainability

 
Coatings chemists face challenges because of regulatory, performance and sustainability requirements and pressures. Inorganic pigments, specifically Complex Inorganic Colored Pigments (CICPs) can address these issues because of their inherent inertness, excellent performance properties and long service life. Three CICP innovations are at the forefront of this push for pigments that are colorful but also have functionality. The first is by using elements in new and novel ways to make new colorants as in the Niobium Tin Pyrochlore (NTP) Yellow and Rutile Tin Zinc Orange (RTZ) to replace lead chromates. The second is the YInMn Blue pigment that allows dark blue colors that are IR reflective. The third is advances in the PG50 chemistry including chromatic options without inclusion of nickel or chrome in the pigment formulation.
