We offer competitive advantages with our Sol-Gel technology through the use of innovative materials. As the leading specialist for surface coating we can provide everything from a single source:
With its Saphiral® sol-gel coating system, EPG AG has developed a way of protecting aluminium surfaces against corrosion and mechanical stress even without anodizing.
Depending on the alloy and manufacturing process, the aluminium surface often shows an uneven, changed appearance after anodizing, which is not visually pleasing. With Saphiral®, EPG AG has developed a coating solution with which the optical disadvantages of the anodizing process can be eliminated. Saphiral® can also be used either with the aid of a topcoat adapted to the customer's colour requirements and functionalities, or directly on an uncoated surface without anodising. Due to the very thin layer thickness - in the range of 5 to 15 micrometers - the haptics of the metal are also retained.
In addition to the optical enhancement of aluminium, Saphiral® offers excellent properties to withstand mechanical and chemical influences: whether abrasion resistance, scratch hardness or resistance to hand perspiration, for example, all customer requirements can be individually adapted.
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.
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.
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.
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.
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.”
