Abstract (en)
[origin: WO2021069848A1] Method for covering the inner surface (2) of a tank (100), the method comprising the following steps: - a) providing a tank (100) made of a composite material, such as a thermoplastic material or a thermosetting material, the tank being configured to receive a pressurised fluid, - b) spraying a liquid composition (6) comprising a fluoropolymer, a prepolymer and a crosslinking agent of the prepolymer onto the inner surface (2) of the tank (100) so as to form a cover layer (7) covering the inner surface (2), and - c) polymerising the cover layer (7) so as to generate a polymeric binder encapsulating the fluoropolymer and form a fluorinated coating (8) covering at least part of the inner surface (2).
