Description / Abstract:
These specifications define the performance requirements of
corrosion protective waxes for vehicle cavities. Cavity waxes can
compensate insufficiencies in the application processes for
phosphate, electrocoat, sealer and paint and improve corrosion
resistance by penetrating into spot welded joints, clinch/hem
flanges and other crevices which are not or only incompletely
filled with sealer or adhesive.
Wax according to these specifications is designed for a nominal
film thickness of 25 - 40 um. The specification does not restrict
the type of material but covers low, medium and high solid
conventional waxes as well as water based and solvent free
materials.
