History

In 1873, Heinrich Byk founded a chemicals factory in Berlin under his name, in which he initially produced soporific drugs. In 1917, the firm merged with the dye and tanning works to form Byk-Guldenwerke AG; the photochemical factory Ernst Lomberg was acquired subsequently. The first BYK additive for coatings came on the market in 1935. It enabled pigments to be distributed evenly in coatings. In 1962, BYK established the site in Wesel, where it commenced production of paint and plastics additives.

BYK has production sites in Germany (Wesel, Kempen, Moosburg an der Isar, Schkopau and Geretsried), the Netherlands (Deventer, Nijverdal and Denekamp), the United Kingdom (Widnes), the United States (Wallingford, Chester, Gonzales, Louisville, Earth City and Pompano Beach) and China (Tongling).

Research and development

BYK invests around 8% of turnover each year in research and development – this is more than double the amount customary in the sector.^[4]
