![]() The hibonite-based pigments are more thermally stable than cobalt blue due to their higher preparation temperature and remain unaltered structurally and optically upon exposure to strong acid and alkali. Its production, however, requires a significant amount of a cobalt ion, Co 2+, that’s hazardous to both humans and the environment.īy analyzing the structure of hibonite-based blue pigments, Subramanian has developed a way to match or surpass cobalt blue’s vividness while using much less of the harmful carcinogenic cobalt ion, or replacing it entirely. Cobalt blue remains a dominant commercial pigment because of its intensity of color, ease of synthesis and wide applicability. So someone has to make the material first, then study its crystal structure thoroughly to explain the color.”īefore YInMn blue, the last blue discovery was cobalt aluminum oxide-based blue, synthesized by a French chemist in 1802. “The reason is because the origin of the color of a material depends not only on the chemical composition, but also on the intricate arrangement of atoms in the crystal structure. ![]() ![]() “Most pigments are discovered by chance,” Subramanian said. Most had environmental or durability issues. Through much of recorded human history, people around the world have sought inorganic compounds that could be used to paint things blue, often with limited success. “We got lucky the first time with YInMn blue, and now we have come up with some design principles,” Subramanian said. Subramanian and his team discovered YInMn blue in 2009 when they were experimenting with new materials that could be used in electronics applications. – An Oregon State University chemistry researcher who made history a decade ago with the accidental discovery of the first new blue inorganic pigment in more than two centuries is again pushing forward the science of color.Īnalyzing the crystal structure of pigments based on hibonite, a mineral found in meteorites, Mas Subramanian of the OSU College of Science has paved the way toward designing more pigments that are stable, durable and non-toxic with vivid hues.įindings from the study, supported by the National Science Foundation, were published in the American Chemical Society journal, ACS OMEGA. They have unbeatable weatherability, heat and chemical resistance, are non-warping and easy to disperse. These pigments are an extraordinary class of inorganic pigments that offer stable, long-lasting color for many applications. This pigment addition adds to their extensive color options in the blue color space.įounded in 1981, The Shepherd Color Company produces a wide range of high-performance Complex Inorganic Color Pigments (CICPs) used in a variety of industries. Shepherd Color has over 90 years of experience developing, optimizing, and manufacturing an extraordinary range of complex inorganic color pigments. This new pigment is an example of Shepherd Color's R&D expertise and decades of developing and optimizing cobalt blue pigments for the plastic and coating industries. Excellent inherent durability for exterior applications.Compatible with special effect pigments.It can also be used in plastics and engineering polymers, and gel coatings. Matt Comstock, who developed the product.Īnticipated uses for Blue 20G599 are high-performance coatings such as coil & extrusion, automotive, industrial, architectural, powder and other coatings. In naming this new blue, what stood out was its chromaticity maximum value also nicked named 'MC Blue' the initials of the Shepherd Color R&D Chemist, Dr. Pigment Blue 28 with world-wide registrations and a broad range of regulatory approvals. With a large leap in color performance, this new Blue is a C.I. This new red-shade blue has the highest red (a*) value and bluest (-b*) masstone values for the maximum chromaticity possible compared to other blue pigments when matching colors. (CINCINNATI, OH, April 19, 2022) Shepherd Color announces the launch of their new specialty Cobalt Aluminate Blue 20G599.
