Finally harmless waterproofing agents through PFC removal

PFC and its by-products are no longer permitted in the production of impregnating solutions. The market for waterproofing agents was hit hard by this. Through intensive research work, nanoCare was able to replace fluorine compounds with silicon oxide. In addition, the other technical properties of the nanoCare waterproofing solution have also been greatly improved.


Challenge of PFC-free waterproofing

Waterproofing serves to protect an absorbent, fine-capillary material against water penetration. Typical applications for waterproofing are tents, sails, awnings, pavilions, garden umbrellas and especially the fabric roofs of convertibles. Since these products are mainly cared for and maintained by the private users themselves, their health safety is of crucial importance. Within the industrial framework, a health hazard for the users can be excluded with the help of suitable rooms, work equipment and prescribed protective clothing. This possibility exists only to a very limited extent in the case of products for end users. Therefore, an waterproofing agent for private users must be as harmless to health as possible. An agent that is PFC-free is a suitable approach to this.


Your advantages of healthy waterproofing


  • PFC-free means harmless to health

An waterproofing agent that is PFC-free can be applied as far as possible without additional measures. Direct inhalation is not recommended, even with PFC-free waterproofing agents. The new agent no longer poses a long-term, direct health hazard.


  • PFC-free is ecological

Having a waterproof convertible roof without polluting the environment is something beautiful. Today's pleasure does not have to be at the expense of tomorrow's generations - on the contrary. Thanks to the improved waterproofing agent, children and grandchildren also have access to first-class products that do not harm their health or the environment. 


  • PFC-free is better

As it turned out, the performance of the silicon-based waterproofing agent is far superior to the old PFC-containing agents. The coating lasts longer and repels dirt and rain better. A slight lotus flower effect was even observed: Water and dust do not penetrate the fibers, but instead lie on the coating. When the wind blows, the rain and condensation water collects the dust and rolls off the surface. Convertible roofs sealed with PFC-free waterproofing agents therefore have self-cleaning properties.


  • PFC-Free is more durable

Tests in the laboratory have shown that the PFC-free waterproofing adheres to the textile surfaces for longer. Even if the fabrics are folded and bent several times, the silicon-oxide-based impregnation remains reliably bonded. Under normal use, only one waterproofing treatment per season is sufficient.


  • PFC-Free is more beautiful

Waterproofing with impregnating solutions containing silicon oxide also enhances the visual appearance of the textile surface. They offer a slight UV protection and reduce fading by the sun. The colors of the fabrics are thus retained longer and the product retains its practical value.


Have you become curious? Then order your test package now. You will receive the innovative impregnation solution from nanoCare in a practical container delivered to your home within a few days. A comprehensive set of instructions is included, which will help you to get your convertible top ready for the season in just a few easy steps.

PFC-free impregnating agents: performance and power

PFC-free impregnating agents offer excellent coating properties for textile fabrics without any health risks. Apart from allergic reactions, the silicon-based impregnating agents are completely harmless to health, but are highly effective. In addition, the silicon-based impregnating agent is ecologically harmless. nanoCare has been able to significantly improve the performance compared to the old formulas. The coatings are more durable and last even under high stress. The convertible roof can be folded up several times and stowed in the roof box - the impregnation is retained.

  • Harmless to health
  • ecologically harmless
  • better coating performance, even under high loads

Use of nanoCare waterproofing agents

nanoCare waterproofing agents are suitable for sealing all textile fabrics. It does not bleach out and does not attack any kind of fibres. Therefore it is equally suitable for cotton, vinyl or nylon fabrics. The range of its applications is correspondingly wide: parasols, awnings, tents, pavilions and fabric roofs of cabriolets can be sustainably waterproofed by nanoCare in consistent quality for many weeks.

What means PFC-free?

PFC means "perfluorocarbon", i.e. they are compounds of fluorine and carbon. The agent was discovered by chance in 1953 and was first produced as a cleaning agent. Later it became a main component of fire-fighting foams, was used in chrome plating and as an impregnating agent. It came under criticism when it was found to be harmful to health. To make matters worse, waterproofing agents containing PFC are contaminated with the by-products PFOS and PFOA. These by-products are also considered extremely harmful to health and their use is now prohibited by law, especially for agents for end consumers. nanoCare has succeeded in replacing PFC with the help of simple silicon compounds, i.e. quartz sand. The result is a product that is completely harmless to health - which at the same time can offer improved performance compared to the old, PFC-containing products.


After drying, the waterproofing agent forms a flexible protective film which lies on the fibres of the textile fabric. The protective film is open-pored, allowing steam to diffuse through it. However, the large water droplets and dirt particles remain on the fabric and are blown off by the wind.

The nanoCare waterproofing agent is applied with a sponge or spray bottle. The containers are very economical and have a long shelf life.

It is not absolutely necessary to wear protective clothing, but we would still recommend it. Gloves, face mask and protective goggles simply rule out all possible skin irritations when working with the nanoCare waterproofing agent. Above all, allergic reactions are avoided in the long term.

As a general rule, we recommend that a convertible with a fabric top should only be washed by hand. The rotating brushes of a car wash are always a heavy load for a soft top. Accordingly, you should renew the impregnation when you have driven the convertible through the car wash.

What our customers say:

"Waterproofing of the convertible is part of the routine work for the season. The fact that a product that is harmless to health and ecologically sound is now finally available is a great relief".

Martin H from Neuwied writes:

"At first I was sceptical whether a PFC-free impregnating agent could still seal my convertible roof properly. But the result was more than convincing. I am thrilled."

Marco S from Saarbrücken writes:

"My children like to camp in the garden in the summer. Thanks to the PFC-free waterproofing agent they can now make their tents rainproof themselves. They are fascinated by the way it works, and I am reassured that nothing can happen to them."
