Reviews

I had some questions on the product. I sent them to SOCOMORE directly and had a very quick reply with the information I needed. Quick product support is rare these days! Thank you!

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.

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.

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.

Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: Do you have the MSDS sheets for the Green Zinc Oxide Primer aerosol can?

Yes, we have added the MSDS for both the green and yellow aerosol cans to the "MSDS" tab of this web page. Please review them there.

Q: I am reconditioning the main rotor blade leading edges on and Enstrom. The manual calls for a Desoto product with mil-p-23377C spec. I am looking for an equivalent in a rattle can. Do any of the PTI Primers meet the spec?

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 Ė 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.

Q: What is the shelf life of PTI Zinc Chromate primer?

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.

Q: Can the PTI Water Reducible Epoxy Primer be shipped during the winter? Or will it freeze?

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.

Q: I'm removing wing struts off a Decathlon. Main strut is aluminum and the aft strut is steel. Can you recommend a PTI primer that would work for both strut materials? And if not a single primer, which would I use for each type metal? Any other considerations I should address regarding these two dissimilar metals?

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.

Q: Can I brush on zinc chromate onto aluminum? I own a Cessna 172M that did not have zinc chromate. I have some bare metal on the interior of the cabin I would like to clean up and then treat with zinc chromate. Using a brush would be a lot easier than masking off parts of the interior to paint a small section (like the interior skin of my baggage door).

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.

Q: If I want to touch up some spots on new aluminum that I may have scuffed the alodine off of, what primer is better, zinc chromate, zinc oxide, or zinc phosphate?

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.

Q: When I order a gallon of this Acid Etching Primer and/or the Polyurethane top coats do I get a gallon of the paint and the catalyst for a total of 2 gallons?

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.

Q: I believe I made an error in applying your Zinc Chromate primer. I applied it directly to an Alcad Aluminum sheet. The adhesion doesn't seem very good. Do I need to Acid etch the sheet prior to applying the primer? My aircraft will be flown on and off the water. Can you give me some guidance on the best why to prime the metal?

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.

Q: I am attempting to re-finish magnesium control wheels that have been stripped bare. Can you recommend a product that will act as a converter to allow primer an polyurethane topcoat?

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.
