The primers provided by Products Techniques, Inc. have been formulated specifically to inhibit corrosion, inhibit degradation, resist harmful chemicals and promote adhesion between the substrate and top coat. Primers can be applied to nearly any substrate used in the construction of aircraft.
Zinc Chromate, Zinc Oxide, and Zinc Phosphate primers are available in aerosols, quarts and gallons. The two component Epoxy primers are available in quart kits and gallon kits. In addition, PTI will provide an aerosol kit for two component Epoxy and Acid Etching primer. To order two component aerosols please fill out the custom request form and email it to PTI@ptipaint.com. We are not able to offer aerosol kits for the Sandable Epoxy and Water Reducible epoxy primers. PTI will also provide material in smaller or larger quantities than what is reflected on this page upon request.
The PTI Primers offered through Aircraft Spruce have been formulated to meet and exceed military, aviation and aerospace industry standards. Please refer to the Technical Data for each top coat to review product descriptions, mixing instructions, application instructions and to identify what coating will work best for your application. If you have any questions with regard to these products you can forward your questions directly to PTI using the button below.
Before ordering solvents, reducers or primers please refer to the:
I rated 5 stars based on Aircraft Spruce reputation as I have not used the primer yet. Be advised, PTI states that primer is only good for a year and that is only applicable if the can is unopened. Also, no thinning instructions on can, but, PTI has a website with a description section and then an extended description section and that is where thinning instructions are.
Another fair price and delivered quickly.
This stuff is well known to be very toxic and respiratory precautions need to be taken however, I found it to be the best solution for protecting worn aluminum. When you restore aged and mild surface-corroded aluminum you typically wear-off the originally milled protective Alclad coating and then fresh oxidation sets in minutes after you clean and prep the surface for priming. This primers self-etching feature solves that problem and then lays down a protective layer of zinc chromate that bonds extremely well to a clean surface. Once dried and cured at 75 degrees and above, it created a scuff-resistant finish on my cabin floor.
Great product and service
Received as ordered.
Good for corrosion touch up repair on exterior paint
Recommend PTI zinc chromate 16 oz can part number 09-00901 for small jobs. Dries quick - thin coats in about 15 minutes. Just sprayed a few parts. Had to wipe off Very tacky Tempo zinc phosphate with a modified epoxy base that was sprayed 18 hrs ago. My can has 6/3/14 production date and sprays like new. Almost out so had to leave this review while on THIS page to order another can.
Excellence in all products
This stuff works great for touching up areas that have had the original primer removed.

Per PTI: Our epoxy primer meets that specification. If you need certifications, then you will need to request them when you purchase the product. Unfortunately we do not have this material in an aerosol can because to meet that specification the product has to be two component (paint and catalyst) and only has a 6 – 8 hour pot life. You can purchase the material in a quart kit and purchase an item called Preval Spray Can. I have provided links to the two said items below. Please review the materials and let me know if you have additional questions.
Per the supplier: Aerosol 6 months. Bulk 1 year and we will recertify the bulk product every 6 months after the first year up to 3 years from the date of manufacturing if the material has been stored properly and the container is not damaged.
Per PTI: It should not freeze, we put additives in it to keep it from freezing. Although it is possible, it is highly unlikley. We have never heard of anything like that happening before.
The Epoxy primer will work for both substrates. We highly recommend, particularly with aluminum, that you use the acid etch primer prior to using the epoxy primer.
Per PTI: yes, this can be brushed on because it is an etching primer, however it is mainly intended to be sprayed. We recommend to take a peak at the tech data sheet we have listed here under the tech data tab so that you can get a good idea of this products characteristics and uses.
They are all quality self-etching primers, so any one should work for this application. You may want a professional painter to evaluate the panel to insure you do not have to re-apply the alodine.
The acid etch primer would come with a quart of catalyst as the mixing ratio for 1 gallon is 4:1. As for the polyurethane top coat, it does not come with the catalyst. Take a look at P/N# 09-01256 for the catalyst.
If you are painting exterior surfaces and planning on applying a polyurethane for the topcoat then you would want to use our Epoxy Primer which contains chromates. For interior surfaces you would use the zinc chromate with an enamel topcoat. As for the preparation of the metal you would want to scuff or etch the metal. Also you do not need an incredibly thick primer coat. 0.6 mils to 1 mil is perfect. Please reference the PTI manual.
Please take a look at our Acid Etching Wash primer. The material is available in green or yellow. You will also need to purchase the PT-1045 Thinner for the primer. The primer is supposed to go on very lightly. Click on the Tech Data tab for more information about this product.
This question with regard to the best primer to use for the battery box is dependent on how much use or impact the box will be exposed to. Commonly the battery box is used infrequently when the battery is being changed. Also, because the battery box will not be exposed to the elements you should be fine using a Zinc Chromate or Zinc Phosphate Primer. I suggest the Zinc Chromate for corrosion inhibiting properties. Both primers are easy to touch up and durable if they are allowed to fully dry and cure before you install the battery. Please see the technical data (Click Here). If you would like the box to be a certain color please use the PTI Enamel (Click Here). Technical data for the enamel can be found on the website as well.
