In the wake of the tragic bridge collapse in Minnesota and last year's shut down of an oil pipeline in Alaska due to corrosion, researchers are facing increased pressure to develop better protective coatings to help save aging infrastructures, according to an article scheduled for the September 17 issue of Chemical & Engineering News.
Protective coatings and paints, such as epoxy resins and polyurethanes, are designed primarily for warding off corrosion in metal-based structures such as bridges, storage tanks and buildings. Part of a fast-growing, multibillion dollar industry, these chemicals have played an important but unsung role in protecting structures for many years, writes C&EN Senior Editor Alexander H. Tullo.
In the article, Tullo highlights efforts by coating manufacturers to balance long-term coating protection with growing customer demand for ease of use and lower prices and societal demands for reducing volatile organic emissions from paints and other coatings. He describes new multi-functional coatings that reduce the number of protective coats applied while retaining maximum coating performance and faster-acting curing agents that get paint jobs finished more quickly.
But disasters aren't the only thing fueling demand for better coatings. A boom in construction work in emerging economies in China, India, and Eastern Europe is also increasing demand, Tullo notes.
