One-Part Anti-Corrosion Wash Primer
Definition:
One-Part Anti-Corrosion Wash Primer -ALN 002 003 10-
Edition 06/2011
Product Description
One-part anti-corrosion primer is a zinc chromate-free, polyvinylbutyral-based, single-component product for vehicle repairs.
With its special pigment and binder composition it provides excellent protection against corrosion, outstanding adhesion and is also certified for welding. Nevertheless, this product non-conductive and therefore not suitable for spot-welding.
For residual rust spots on corners and edges as well as bare-sanded areas, we recommend recoating using One-Part Anti-Corrosion Wash Primer -ALN 002 003 10- with a Two-Part HS Filler.
