Corrosion Protection for Stainless Steel and Titanium with Nanoseal®

The demand for high-quality surface finishes with corrosion protection is high worldwide, especially in the automotive industry. EPG AG provides tailored solutions for exterior components that not only prevent corrosion but are also resistant to chemical attacks and mechanical abrasion.

Nanoseal® is a glass-like protective coating that achieves excellent results on metals such as stainless steel and titanium. The main characteristics:

Excellent corrosion protection and abrasion resistance: in numerous tests, nanoseal® achieves better results than conventional processes like chrome or PVD.

High temperature Resistance: the coating remains stable even at temperatures up to 500 °C.

Excellent appearance: the metallic aesthetics are preserved, and structures like brushing or polishing remain visible.

Additional functions: anti-fingerprint coating, tarnish protection, and even flexibility for versatile applications.

The coating process is efficient and cost-effective: after cleaning the metal substrates, Nanoseal® is applied in a thin layer by spraying and cured at 300–500 °C.

Application Areas of Nanoseal®:

Exhaust systems such as tailpipes and mufflers.

Body parts and decorations like running boards or trim strips.

Thanks to its flexibility and versatility, Nanoseal® is equally suitable for polished and brushed surfaces.

Corrosion Protection for Aluminum with Saphiral®

Aluminum is popular due to its light and aesthetic properties but is susceptible to corrosion, abrasion, and scratches. With Saphiral®, EPG AG offers a state-of-the-art solution that eliminates these disadvantages while preserving the natural appearance of the metal.

Properties of Saphiral®:

Layer thickness of only 10–15 µM: this ensures a transparent, barely visible coating.

Effective protection against corrosion, abrasion, and scratch resistance.

Alternative to anodizing: with a single-stage spray coating process, Saphiral® can replace the complex anodizing process.

Versatile design possibilities: numerous colors and surface effects are achievable.

Application Areas of Saphiral®:

Automotive Industry

Trim strips and panels in the interior.

Design and Architecture Industry

Refinement of trim strips, fittings, and handles.

Household Appliances

Coatings for kitchen equipment, decorative strips, or handles.

Aviation Industry

High-quality solutions for coatings of aluminum parts in aircraft interiors.

Sustainability and Future Prospects

All coatings from EPG AG are environmentally friendly and comply with the REACH regulation, which regulates the use of hazardous substances in the industry. This makes EPG's solutions particularly attractive to companies that value sustainability and legal compliance.

With Nanoseal® and Saphiral®, EPG AG offers versatile and highly functional alternatives to traditional coating processes such as chrome plating and anodizing. The products combine elegant appearance, corrosion protection, and environmental protection, making them ideal for the challenges of modern industries.
