PPG

You won't catch PPG Industries painting itself into a corner. Coatings -- such as paints (Pittsburgh Paints, Lucite, and Monarch), stains (Olympic), and sealants -- account for most of its sales; the remainder comes from glass, chemicals, and specialty materials. PPG's glass offerings include flat glass for buildings, fabricated glass, and continuous-strand fiberglass used in aircraft and buildings. Its chemicals segment makes chlor-alkali chemicals, and the specialty materials unit provides silica products. The company also makes optical products like Transitions brand lenses. PPG operates more than 120 manufacturing facilities worldwide and owns 450 retail centers in the US, Africa, China, and Australia.
