eveloped by Douce-Hydro “Research &
Development” team, KERADOUCE® is a multilayer
coating, waterproof and very hard, which is applied on
the rods of hydraulic cylinders and dampers, and has
an excellent corrosion resistance. It is homogeneous,
uninterrupted, non conducting, flexible enough to
support functional rod bending, and ecological.
Since 1990, with thousands of hydraulic cylinders and
dampers in use worldwide, our KERADOUCE® coating
has proved its high efficiency and reliability.
