We enable our customers, for instance, to change the appearance, image and functionality of everything from product packaging to automotive finishes by controlling the way light is absorbed or reflected from the surface of a particle. Manipulating that same particle to absorb or repel water produces an entirely new set of applications. \r\n\r\nAnd that's only the half of it. Because we then use surface chemistry to expand the performance profile and functionality of these engineered materials # creating specialized chemical formulations to tailor their acidity, thermal stability, gloss and other characteristics. The formulations are typically metal-based, predominantly platinum group metals. \r\n\r\nThe result may be a catalyst that cleans a car's exhaust or a pigment that gives eye shadow its pearlescent sheen. Either outcome is made possible by the very same capabilities in materials science and surface chemistry. \r\n\r\nWhether delivering more cost-effective crop protection or helping a petroleum refiner get the most from a barrel of crude oil, we're in the business of making our customers' products and processes more effective, less costly, more productive, more attractive, safer and more environmentally friendly. \r\n\r\n
