The advantages of sol-gel based coating systems for complex component groups
Aesthetic surfaces of metals coupled with high functionality have become essential in many areas of daily life. EPG AG’s coating systems are also suitable for component groups made of different metals.
EPG AG's innovative coating systems have been on the market in the automotive industry for a long time and are gaining increasing popularity in other sectors as well. A large number of metals can be refined with sol-gel-based systems. These can be applied as an invisible transparent protection for brushed, blasted or highly polished metal surfaces, which are protected against contamination, which are robust against external influences such as scratches or aggressive substances, or have a high corrosion protection or a special temperature stability.
By selecting suitable pigments, the coating lacquers can also be produced in color. EPG offers a wide range of color pigments for this purpose. At the customer's request, suitable mixing processes of different color pigments and measurement of the corresponding color values can be used to produce reproducible, customized colored coatings. We can also adjust the desired gloss levels, e.g. matt or high-gloss coatings.
Due to the very low layer thickness, the metallic character of the substrate is retained; brush structures or surface reliefs remain visible even after coating.
The coloured coatings can be applied to aluminium as well as stainless steel or other metals. Thus this technology also enables the coating of complex component groups composed of different metals with the result of a uniform colour image on the surface.

We apply coatings to metallic surfaces
Stainless steel
Our top product NANOSEAL® sets new standards in the provision of finishes for stainless steel. Surfaces are given a wafer thin coating, to ensure they retain their original metallic appearance. Various color options are available.
Aluminium
Its typical lightweight character makes aluminum an increasingly popular metal nowadays for use in automobile, household and general design applications. Our environmentally-friendly technology SAPHIRAL® can improve upon, and sometimes completely replace, anodized aluminum, and is in addition available in many color variations.
Titanium and other metals
The EPG technology protects titanium and other metallic and non-metallic alloys. Among other new approaches, we are currently developing a new technology to protect carbonaceous steels.
Application areas
We enhance both internal and external components made from aluminum and stainless steel – for decorative purposes and to protect them against corrosion.
With our technology we enhance the appearance of corners, edges or decorative sections and thus preserve the high-quality appearance of designs items in the long term.
Household and kitchen equipment withstands the strains of daily use thanks to our coatings..
It doesn’t matter whether it relates to housings, switches or buttons: we can enhance and protect your electronic products with our innovative anti-fingerprint or easy-to-clean technologies.
We develop innovative composite materials for sand consolidation and proppant binding, and these are used as binding materials in the oil and gas industries. In this way, we increase the productivity of oil and gas resources throughout the world.

Frequently asked questions (FAQ’s)
EPG coatings are distinguished by very thin application layers, but these layers nevertheless feature extremely high resistance to corrosion and environmental influences and a high level of scratch resistance. The layers are so thin that they can hardly be seen by the naked eye, and as a result the characteristics of the metallic surface are retained both in terms of touch and feel as well as optically.
Yes, we develop customized solutions for our customers’ products.
If requested by our customers, we are also able to coat samples – including original components. Our experts will be delighted to offer you their advice for this purpose.
Our coatings are subjected to all the quality tests which are important in the relevant industrial sector: e.g. mechanical tests such as abrasion and scratch resistance tests, salt mist tests and tests to check resistance to chemicals. The results can also be seen in our publications.
In addition to anorganic-glass-type systems which are extremely stable even at high temperatures up to 600 °C, EPG can offer hybrids with an anorganic-organic matrix, which display better characteristics when compared with purely organic systems.
Our product SAPHIRAL for the coating of aluminum convinced an independent jury
EPG AG wins Industriepreis 2017 in the category “Suppliers”
With its new product SAPHIRAL, an innovative coating solution for all current forms of aluminum alloy, EPG AG comfortably won the Industriepreis 2017 in the category of suppliers. SAPHIRAL is a Sol-Gel-based coating solution for all existing types of aluminum alloy, with outstanding functional and optical characteristics. SAPHIRAL exhibits a very high degree of scratch resistance, as well as great thermal and chemical stability. SAPHIRAL makes it possible to produce single-layer solutions for high-gloss, brushed or blasted substrates, with an extremely high-quality surface finish. SAPHIRAL can be applied directly on aluminum surfaces (colored coatings are possible) or can alternatively be employed to improve the qualities of anodized surfaces. This prestigious award, which is decided by an independent specialist jury comprising professors, scientists and experts from a variety of industrial sectors and publishing houses, is announced once annually by the Huber Verlag, a publishing house for new media, on the occasion of the Hannover Messe, Germany’s largest and most important industrial fair. On each occasion, prizes are awarded to the most advanced industrial products in 14 different categories. The Chairman of the Board of EPG AG, Dr. Andreas Zimmermann, was absolutely delighted at this recognition: “The awarding of this prize is for us both a confirmation and an acknowledgement that our innovative development work is at the absolute peak of current technology. Our solutions make it possible to offer the end customer a significant possibility of differentiating his products from the competition and of increasing their value.”
