PreKote Surface Pretreatment


SKU: N/A Category: Tag:

PreKote is a simple procedure that replaces the use of traditional chromate conversion coatings and eliminates the need to use acid etches, solvent washes, and other toxic processes.

Small aircraft shops use PreKote to replace the use of chromate conversion coatings pens for smaller repair areas. By eliminating the need for these additional processes, paint preparation time and cost can be reduced by up to 40%.

PreKote is approved for use by the Boeing Commercial Aerospace Group, Department of Defense, and over 1,500 United States Air Force aircrafts.

PreKote has proven consistent results with a variety of paints and primers. Use it on a wide range of surfaces, including aluminum, steel, magnesium, titanium, CRES, galvanized, composite and plastic surfaces.

Using PreKote does not trigger categorical industrial user status under the Environmental Protection Agency's Metal Finishing effluent guidelines, which makes PreKote easy to dispose. PreKote also eliminates the need for forced air containment suits which are required by OSHA when using traditional chromate conversion coatings. Simply rain gear and goggles/face shield are all that is required.
