Underseal black is a thixotropic mixture of bitumens, synthetic resins, solvents and special inhibitors. After evaporation, a tough elastic film remains which provides protection against environmental effects and corrosion from de-icing salt. Underseal black has excellent corrosion protection properties. The product is thixotropic and is therefore applied as a non-drip coating. This means that the product can be painted on in thick layers within a single application.

Corrosions protection agent that forms a toughened, sealed, protective film when dry. The bituminous coating material has good anti-droning action and high abrasion resistance. High amount of solids content. Cannot be painted over.


For covering spray paint mist in wheel arches and for repairing or complementing existing coatings on vehicle underbodies.

Underseal black is suitable for the coating of unpainted and painted surfaces on vehicle underbodies and wheelhouses and repairing or supplementing existing coatings.


Surfaces which have to be treated with underseal black must be thoroughly cleaned beforehand. Rust must be removed. The surfaces must be dry and free of wax, dirt and grease and extensively free of dust. The material is best suited for use at room temperature. Shake can vigorously. When the ball has worked loose, continue to shake the can for a further minute. Hold the can vertically when spraying and spray thinly at a distance of about 20 - 30 cm from the surface. The resistance to abrasion and corrosion increases with increasing coating thickness. For this reason, the spraying process should be repeated once or twice after a short flash-off period. Underseal spray should be sprayed using a cross pattern to avoid spray shadowing.
