Strict REACH regulations require a rethink, and many customers are looking for environmentally friendly coating processes.
For more than 15 years, EPG AG has been developing coating solutions based on sol-gel technology that can provide an alternative to chrome-plated surfaces. With the products, Nanoseal® for the high-temperature range and Saphiral® for the low-temperature range, ultra-thin coatings are accessible that allow the look and feel of the metals to be preserved, and many color nuances set interesting and fashionable accents that are appreciated by customers.
Both Nanoseal® and Saphiral® are REACH-compliant coatings. Since they are mainly made of glass, they do not contain any substances relevant to health or the environment and are even suitable for use in the food industry. The advantages are obvious, offering customers a good alternative to chrome-plating processes and other environmentally harmful coatings.
Coatings on plastic surfaces and with biocidal effects are currently under development. The first tests present good results and show that the sol-gel technology can also offer solutions for these areas.
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:
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.”
