Next came acquisitions, funded in part by the divestitures, that reinforced the learning base in the paths that the firm had long followed. In films and fibers it purchased Exxon s carbon fiber business in 1984, Exxon s film composites activities in 1985, and Hercules s olefin fiber carpets in 1989. Later, in 1992, it traded its acrylic assets to ICI for the latter s nylon business, plus 41 million. In paints and finishes Du Pont obtained Ford s North American automotive paint division in 1986, followed by a joint venture with ICI to expand the same market in Europe, and one with Kami Paint to do so in Japan and East Asia.

Solvent power of a hydrocarbon solvents is determined by kauri-butanol value. The method applies to solvents having a boiling point above 40 C and a dry point below 300"C. The method is most frequently used to evaluate solvents for applications in paints and lacquers. The kami-butanol value is the volxune of solvent required to produce a defined degree of turbidity when added to 20 g of a standard solution of kauri resin in n-butanol (400 g of resin in 2000 g of solvent). High kami value indicates a relatively strong dissolving power. The method is standardized using 105+5 ml of toluene.
