Nano-Scale Liquid Glass Coatings

Protection for (Stadium) Seating

7641 is a high-quality two-component hybrid coating based on an epoxy-siloxane system, specifically developed for heavily used surfaces. The coating forms a highly transparent, glossy protective layer with a thickness of approximately 5–20 µm, which is significantly more durable than conventional nano coatings.

At a typical coating thickness of approx. 15 µm, the theoretical coverage is about 60–80 m² per kg of material, depending on the substrate, application method and surface structure.

After application, a hydrophobic and oleophobic protective layer is formed, which significantly reduces the adhesion of water, dirt and many types of contamination. This results in a pronounced “easy-to-clean” effect, allowing stadium seats to be cleaned faster and with reduced labor effort.

The coating offers very good resistance to UV radiation, weathering, cleaning agents and mechanical stress, making it ideal for heavily used plastic surfaces both indoors and outdoors. At the same time, it provides a slight color enhancement and visual refresh of the surface, allowing older plastic seats to regain a fresher appearance.

In addition, the coating provides anti-graffiti properties, as many paints, markers or contaminants adhere less strongly and can be removed more easily.

7641 is PFAS-free, can be recoated and is suitable for numerous materials such as plastics, GRP, metal, stone or concrete.
