• DELO is a leading manufacturer of high-tech adhesives and other multifunctional materials as well as adhesive dispensing and curing technology.
• The company's products are primarily used in the semiconductor, automotive, and consumer electronics industries. Almost every cell phone contains a tiny drop of DELO adhesive, which manufacturers use to produce key components such as cameras, microphones, and loudspeakers.
• According to management consultant and economics professor Hermann Simon, this makes the adhesives specialist one of the Hidden Champions. Hermann Simon: ‘The global economy could run without Toyota, but not without DELO adhesives.’
• Customers that use DELO adhesives include Bosch, Huawei, Mercedes-Benz, Osram, Siemens, and Sony.

• DELO was founded in 1961, achieving great success in 1989 when it introduced a patented light curing technology, commonly used in dentistry, to the industrial sector. For the first time, it was possible for adhesives to reach full strength by short exposure to ultraviolet light, making them suitable for many high-volume assembly processes
• In 1998, Sabine Herold and Dr. Wolf-Dietrich Herold took control of the company in a management buyout, leading the business ever since. In 2022, Dr. Karl Bitzer and Christian Walther were also appointed to the Management Board.

• DELO employs nearly 1,200 people.
• Revenue in the 2025 fiscal year (ending March 31) amounted to 245 million euros, with more than 80 percent generated abroad.
