Vacuum Plasma Coating - Makes materials surprisingly water- and oil-repellent
An invisible fluoropolymer coating, just a few nanometers thick, is applied in a vacuum plasma process. The coating is permanent and makes the coated object highly water-repellent (hydrophobic) and oil-repellent (oleophobic). The coating can be applied on a variety of substrates including plastics, metals, paper, and textiles. The process is gas-based and therefore coats complex geometries including non-visible internal cavities.
The process is used to waterproof mobile phones, hearing aids, sportswear, technical textiles, and industrial filters.
Plasma (an ionised gas) is used in a vacuum environment to activate the surface of the object to be coated. A monomer is then applied as a vapour that binds to the activated surface. Further plasma treatment causes the monomer to polymerise, thereby forming the nanocoating. The coating is applied at a temperature below 40°C, so most materials can be coated. Coated textiles do not show reduced breathability. The vendor sells turnkey processing solutions.

The samples measure approximately 90 mm x 90 mm. One of the samples is coated and it will not absorb water. Dip both samples in water to see the difference.
All samples come with a laminated information card, which includes contact details for the supplier.
