Prekote Surface Pretreatment
Overview
|
PreKote© a simple procedure that replaces the use of traditional chromate conversion coatings and the need for acide etches, solvent washes and other toxic processes. Small aircraft shops have also used PreKote© to successfully replace the use of chromate conversion coating 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%. Approved for use by the Boeing Commercial Aerospace Group, Department of Defense and currently flying over 1,500 United States Air Force aircraft, PreKote© has proven consistent results with a variety of paints and primers. PreKote© can be used on a wide range of surfaces including aluminum, steel, magnesium, titanium, CRES, galvanized, composite and plastic surfaces. Environmental, Health & Safety Reason for Using PreKote PreKote© use 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. |

Reviews
Bought this to paint the RV-10. Seems to work great with 3M pads. 1 gallon should do the entire airplane. Too bad this stuff is outrageously priced by ACS. Then you get gouged on the shipping too! Best to buy direct from manufacture.

1 quart of Prekote came in a box with a sprayer that screws into the bottle. The sprayer didnt work. Price had almost doubled from that quoted in my 2-year old A.S. catalog. With the $20 shipping this stuff was about three times the original price. The Prekote was easy to use though, a lot easier than Alumiprep followed by Alodyne.

Too early to tell. Job is complete and well see if it blisters/peels.

Works as described- my first time using this product. It did an excellent job of prepping my aluminum boat for paint. My order arrived quickly, I will buy from Aircraft Spruce again.

Used this on some ruddervators for a super vee that is being put back together. Looks like good adhesion to the old magnesium. Will see how they hold up.
Great Producct ! I couldnt believe how much oxidation came off the parts. I sprayed it on then scrubbed with maroon scotchbrite in two directions and rinsed it off. Very ECO friendly and safe to use. Forget the alodine etc. AKZO works amazingly well with this simple prep.

The volume of PreKote SP required to treat a given surface varies with the dispensing method. Higher volume dispensing systems (drum pumps) used for treating an entire aircraft will use one gallon of PreKote SP to treat 120–160 square feet. Low volume trigger spray bottles will yield 200–300 square feet per gallon of PreKote.
Per the PreKote web site, PreKote has been proven to be compatible with any epoxy or urethane primer, or top coat, from major manufacturers, and can be used on any part that will subsequently be primed.
The mfg @ for the quart size is 065-1002.
