Tunap Sports presents a surface protection spray that forms a hydrophobic protective layer on frames and components. The formula does not contain PFAS or fluorinated compounds. The spray is suitable for both matt and glossy surfaces and contains UV protection to preserve the gloss of the paintwork. The 300 ml spray can costs 13.95 euros.

Anyone who uses their bike regularly knows the problem: after every ride out in the rain or on muddy paths, dirt sticks to the frame, attachments and plastic surfaces. Cleaning takes time and effort. Tunap Sports has now developed a surface protection spray designed to reduce this effort.

The product forms a hydrophobic protective layer that causes water and dirt particles to roll off - we all know this phenomenon as the lotus effect. The surface remains smoother, dirt adheres less strongly and can be removed more quickly during the next wash. The maintenance effort should be noticeably reduced, especially for commuters with e-bikes or year-round riders.

Application on matt and glossy surfaces

The special feature: the spray is designed to work equally well on matt and glossy surfaces. It can be applied to frames, add-on parts and plastic surfaces. It is applied to dry surfaces after washing the bike. Any excess liquid is spread with a cloth. However, care should be taken to avoid brake discs and brake pads so as not to impair the braking effect.

The formulation is temperature-resistant and remains stable even when exposed to sunlight or higher surface temperatures. Integrated UV protection should help to ensure that paint colours fade less quickly. According to the manufacturer, the coating can withstand several washes before it needs to be reapplied.

No PFAS and fluorochemicals

During development, Tunap Sports completely dispensed with PFAS and fluorine-containing compounds. These substances are criticised because they accumulate in the environment and are difficult to break down. These substances are also better known as perpetuating chemicals. Björn von Dressler, Head of Tunap Sports, explains: "Our aim was to develop a protective solution that is both technically convincing and fulfils the increasing requirements for sustainability."

The formula is designed to combine material compatibility with protection technology. The bike is protected from water, dirt and UV rays, which can contribute to a longer service life of the frame. For riders who frequently use their bike in changing weather conditions, this means less maintenance and a permanently fresh look.

The Tunap Sports surface protection spray is now available from specialist retailers, sports and outdoor retailers and online. The 300 ml spray can costs 13.95 euros.
