Perma Film Transparent 1L Underbody Protection Transparent Long-Term Rust Protection Coating Thanks to the compatibility with deep-penetrating Fluid Film, the PERMA FILM system can be used with a significantly lower surface preparation standard than paint coatings, which reduces the cost of repair up to 80%. Perma Film is a resin dissolved calcium sulphonate compound, which offers a high passive corrosion protection. The first thinly mist fluid film serves as an active primer, which penetrates existing rust and existing coatings into the structure of the material, blocks oxygen and displaces existing residual moisture and acts as a link. Thanks to the water-displacing properties of the fluid film, cost-intensive drying of the surfaces can be dispensed with. The combination of Fluid Film with Perma Film creates a flexible active layer with the grip-resistant and abrasion-resistant surface, which provides optimal protection. Areas of application: ballast water tanks industrial systems wheel arch boxes winter service underbody Features: Thanks to the combination with Fluid Film, the system remains flexible, hardens on the surface and combines the positive properties such as the penetration ability of Fluid Film with those of a non-slip protective layer. Application: Perma film can be easily applied with a brush or roller in 2 layers. The processing can also be done with compressed air. For dilution, we recommend Max. 5% turpentine substitute.
