About this member

Zeller+Gmelin is an independent, medium-sized family business that was founded in Eislingen in 1866. Over the decades, Zeller+Gmelin has developed into an international partner for high-quality lubricants as well as printing inks and chemical products.

With around 1,000 employees and 17 subsidiaries worldwide, Zeller+Gmelin delivers to more than 80 countries around the world and, in addition to Eislingen, has several foreign production locations. The high-quality products occupy a leading position on the international market. We value individual and holistic solutions and offer research, development and production - all from a single source - from experts.

The conscientious use of resources and responsibility towards future generations are central components of our company philosophy. We have been working successfully on reducing our ecological footprint for years and, since January 2020, we have been able to call ourselves a “climate-neutral location” as the first chemical company in Baden-Württemberg. Our research and development departments are continuously working on innovative solutions that reduce the burden on the environment and improve customer processes.

We see innovations as a core competency. At our headquarters in Eislingen alone, around 20% of the employees work in research and development. We are constantly striving to further develop and optimize our products – and to bring new innovations onto the market.

We are understanders + solvers and have been for more than 150 years. Because we understand the customer and develop solutions – reliable, flexible and tailor-made. We owe this to the quality of our work and of course the experience, competence and passion of our employees.

High Purity Cleaner

Divinol CL1 Dipcleaner 1528

  • Critical HIO elements such as phosphorus, sulfur, silicon, tin and zinc are <2 ppm in the concentrate
  • free of heavy metals
  • salt-free
  • Nitrogen and phosphorus free and therefore harmless for water treatment

Divinol CL1 Dipcleaner 1528 is suitable for the high purity cleaning of components in the semiconductor supply industry such as EUV lithography systems. In addition, the cleaner can also be used for the optoelectronic industry, in high vacuum technology and in medical technology. The product is suitable for cleaning aluminum alloys such as AL 5083, titanium, stainless steel and is compatible with non-ferrous metals. In order to meet the high requirements for component cleanliness, the cleaner must be prepared with water of the appropriate purity. Divinol CL1 Dipcleaner 1528 removes particulate, filmic-organic and inorganic contamination from the surface. From the recommended use concentration of 55 °C, the cleaning solution is foam-free. The concentration is determined via the conductance.

Coagulating and flocculant

Divinol Flockungsmittel RB

Divinol Flockungsmittel RB is a liquid paint coagulating agent based on inorganic separating agents and special polymers. It can be used for a variety of paint binding systems. It’s mainly used to coagulate water-based paint, but can also be used to detack solvent-based paint

Divinol Flockungsmittel RB is suitable for water wash spray booths with various discharge systems. Due to its good detackifying and dewatering effect, a compact coagulate is produced, which can be easily removed with the usual discharging equipment. The water service life is thereby increased and the cleaning time is reduced to a minimum.

In combination with one of our Divinol flocculants, specifically heavier paint systems can also be discharged on a floating basis.

Lubricants for the semiconductor supply industry
Zubora 62 H Extra L
Boron-free, semi-synthetic and finely dispersed cooling lubricant of the latest generation

  • semi-synthetic, water-miscible high performance cooling lubricant
  • on the basis of mineral oil
  • with high content of polar additives
  • long-term stable
  • excellent corrosion protection
  • free of formaldehyde releasers and boron
  • free of phosphorus and zinc compounds
  • very low content of sulphur and silicon
  • plastic compatibility in accordance with VDI 3035

Due to selected highly effective additives Zubora 62 H Extra L is suitable for cutting processes of most difficult demand. The product is suitable for machining steel, cast iron and aluminum, as well as for very sensitive aluminum alloys, such as AL 5083 used in lithography systems.


Zubora TLC L

Fully synthetic and water-soluble, boron-free cooling lubricant for aluminium and stainless steel

  • water-soluble and low-foaming cooling lubricant based on glycol
  • free of mineral oil
  • on the basis of fully synthetic anionic and non-ionic lubricating components
  • as well as effective corrosion inhibitors
  • also suitable for very sensitive aluminium alloys, such as AL 5083
  • high long-term stability
  • very good foaming behaviour in deionised water
  • high re-solubility
  • excellent drain off behaviour
  • free of formaldehyde releasers and boron
  • free of phosphorus and zinc compounds

Due to the selection of highly effective additives, Zubora TLC L can be used for medium-heavy machining processes. The product is particularly suitable for machining aluminium and especially sensitive aluminium alloys, such as AL 5083 used in lithography systems. In addition, machining of cast iron, steel and stainless steel is also possible.


Zubora 65 M Ultra L

Boron-free, semi-synthetic cooling lubricant of the latest generation – for most difficult metal cutting operations.

  • semi-synthetic, water-miscible high performance cooling lubricant
  • free of boron
  • on the basis of mineral oil
  • with high content of polar additives
  • with EP additives
  • long-term stable
  • excellent corrosion protection
  • free of formaldehyde releasers

Due to selected highly effective EP additives Zubora 65 M Ultra L is suitable for cutting processes of most difficult demand. The product can be used for machining steel, stainless steel, cast iron and aluminium and also for aluminium alloys as AL 2024 and 7075. Due to a special formulation Zubora 65 M Ultra L is particularly biostable.The EP-additives effect a longer tool life and enable the working with high cutting speeds. Zubora 65 M Ultra L has an optimised foaming behavior which is adapted to a high circulation index. Thus, a high process security can be guaranteed even for very difficult working operations.
