Anticorrosion coatings
For this we offer our patented coating systems Jumbo I, II and III in the area Corrosion Protection on. Until the development of the jumbo systems, fluorothermoplastic systems had a max. limited to 1 mm layer thickness. By the patented sandwich construction of the jumbo systems layer thicknesses of up to 2 mm can be built up even on difficult substrates.
