En la pagina indican que no funciona sumergido constantemente:
This is a quote from there FAQ sheet:
"# 24 - Can you use Ultra-Ever Dry where it is continuously submerged in water or liquid, like the inside of a pipe with constantly flowing liquid?
No, this is not a good application. The reason is the nano-coating relies on a barrier of oxygen/air to form the barrier on the surface of the material it is coating. Unless the coating can become exposed to air every now and then, it cannot “recharge”. So coating the inside of continuously flowing pipes is not a prime application. If it is intermittent usage, it may work well. Steel coated with Ultra-Ever Dry has been immersed in salt water for 30 days without any effect."
Mas o menos, parece que la nano-tecnologia que usan crea como una especie de microcolchón de aire por donde resbalan los líquidos (me lo imagino como aquel juego de salón tipo pingpong de los discosde teflon en una mesa - colchon de aire). Por lo tanto si no "recarga" de aire, no va. En la pregunta hablan de una tuberia con fluido de liquido continuo y parece que con uso intermitente y con periodos vacios (aire) podria funcionar, pero no en inmersion . La última frase me desconcierta
