Certificate:
Anti-corrosive coatings
- Reaction containers for the chemical industry
- Thermometer protection tube
Medium: H2SO4
Service temperature:
130°C-150°C
For this purpose, we offer our patented coating systems Jumbo I, II and III. Before the development of the Jumbo systems, fluorothermoplastic systems were limited to a maximum coating thickness of 1 mm. The patented, sandwich-like composition of the Jumbo systems allows coating thicknesses up to 2 mm even on challenging surfaces.
Anti-corrosion coatings with PFA, FEP, ETFE
Coating thickness up to 2 mm
Service temperature up to 160°C
Chemical resistance: very good
Conductivity: if required
