NOVOL GRAVIT 640 Cavity Wax Corrosion Protection (1liter)

NOVOL GRAVIT 640 Cavity Wax Lanolin Corrosion Protection Coating

NOVOL GRAVIT 640 is a one-component wax and lanolin-based cavity protection material designed for corrosion protection of closed vehicle body cavities. The product cures at room temperature through solvent evaporation and forms a flexible, sealed protective coating on the treated surface.

Thanks to its excellent creeping ability, it penetrates well into gaps, joints and hard-to-reach cavities. The resulting coating provides effective protection against water, salt and corrosion, making it especially suitable for doors, bonnets, sills and other closed body cavities.

GRAVIT 640 does not react with fully cured paint coatings, so it can also be used for cavity protection on properly prepared and previously coated body panels.
