Aluminum is a difficult substrate to coat and requires a primer coating prior to application of a high performance coating. A “universal primer” is a primer suitable as an undercoat for top-coats based on various chemistries (epoxy, polyurethane, etc.). In the case of aluminum, the product most suited to be a universal primer is based on an alkyd resin formulation. This CP describes a phenol-modified alkyd resin based primer for use on aluminum substrates, and compatible with various types of high performance coatings which would be subsequently applied.
