Switzerland's Sika AG, a specialty chemical maker, is buying E.I. DuPont de Nemours & Co.'s protective coatings product lines.
The assets being acquired are designed to protect concrete, steel and other materials from corrosion, water, fire and environmental forces, DuPont said Monday in a statement.
The deal, which must be approved by regulatory authorities, includes a DuPont factory at Vaihingen, Germany, where the coatings are made.
The price of the deal was not disclosed.
