Hexion Specialty Chemicals is the world's largest thermosetting resins (or thermosets) maker, ahead of Georgia-Pacific. Thermosets add a desired quality (heat resistance, gloss, adhesion, etc.) to a number of different paints and adhesives. Hexion also is among the largest makers of formaldehyde and other forest product resins, epoxy resins, and raw materials for coatings and inks. In 2007, the company agreed to buy Huntsman for $10.5 billion. However, amid the general economic turmoil of 2008, Hexion pulled out of the transaction toward the end of that year. Apollo Management controls more than 90% of Hexion.
