Pantheon PreKote Surface Pretreatment - AFI32-7086

PreKote replaces the use of both chromate and non-chromate conversion coating systems, replacing acid etches, solvent washes, and other toxic substances on metal and composite substrates prior to priming and painting for many applications, which means reducing water usage and processing time by as much as 40%.

PreKote technology promotes paint adhesion directly to permanently embedded contaminants.

PreKote is Hexavalent chromium-free, non-toxic, and biodegradable.

The application process deposits a layer that bonds to the surface of metal or composite material. This layer has af? nity for metals and organic coatings, which allows the coating to get closer to the substrate surface than traditional pretreatments. With this technology, the PreKote process creates a stronger bond between substrate and primer or primer and topcoat. It is important to recognize that PreKote is not a conversion coating, does not permanently change the surface of the substrate, and is designed to be an integral part of a coating system, allowing for increased corrosion resistance due to a stronger bond.

PreKote also provides a polar/non-polar molecule that attaches itself to permanently embedded contamination and attracts the coating. In contrast, traditional conversion coatings containing heavy metals such as chrome or zinc have no mechanism by which to attach themselves to permanently embedded contamination, resulting in coating failures such as blisters and outgassing (pinholes).
