About BYK

We are an internationally active, industry-leading manufacturer of additives and measuring instruments and as one of the four divisions of the ALTANA Group, we employ around 2,500 people. In 2022, sales amounted to EUR 1,371 million. Additives are chemical admixtures that, dosed in small quantities, improve product properties such as scratch resistance or the gloss of surfaces. Manufacturing processes are also optimized by adding additives.

Every year, BYK invests around 7 % of sales in research and development – this is three times more than most in the sector. One in five employees works in interdisciplinary teams that drive new developments forward and combine their skills across disciplines. The coating, printing inks, and plastics industries are among the main customers of BYK additives. However, BYK additives also improve the product properties and manufacturing processes in the oil & gas industry, the manufacture of care products, adhesives, and sealants, and in construction chemistry. BYK testing and measuring instruments effectively assess the quality of the color, gloss, and appearance as well as the physical properties of paint, plastic, and paper products and are an essential part of quality assurance.

As a global specialty chemicals company, BYK has production facilities in Wesel, Kempen, Schkopau, Moosburg, and Geretsried (Germany), Deventer, Denekamp, and Nijverdal (the Netherlands), Widnes (Great Britain), Wallingford, Chester, Columbia, Earth City, Gonzales, Louisville, and Pittsford (USA), as well as Shanghai and Tongling (China).
