BYK is a leading provider in the field of additives and measuring instruments. Additives are chemical accessory agents that improve product characteristics such as scratch resistance or surface gloss - even when dosed in small quantities. Additives can be used to set the flow properties of liquid materials such that ideal conditions prevail for problem-free manufacturing and application processes.


The coating, printing-inks and plastics industries are some of BYK's main customers. Yet BYK additives also improve product characteristics and manufacturing processes in the oil and gas industry, the production of care products, the production of adhesives and sealing compounds, as well as in building chemistry. BYK testing and measuring instruments effectively assess the quality of paint, gloss and appearance, as well as the physical characteristics of coating, plastic and paper products, and are an essential part of quality assurance.


As a globally-operating specialty-chemicals company, BYK has production sites in Wesel, Kempen, Moosburg, Schkopau and Geretsried (Germany), Deventer, Denekamp, Nijverdal (Netherlands), Widnes (Great Britain), Wallingford, Chester, Gonzales, Louisville, Earth City (USA), as well as Shanghai and Tongling (China). The company today employs more than 2,300 people worldwide and is a member of the ALTANA Group.
