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.

• Epoxy Primer Technical Data Link
• Aircraft Paint and Application Manual

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.

Yes, all but the aerosol can are designed to be brushed on.

The epoxy primer can be applied over Alodine. It should be applied over an Alodined surface as soon as the process is complete so that the metal is protected.

Epoxy primers, Acid Etch wash primers, and sandable primers are 2 part primers. All three types are sold as kits with both Part A and Part B, catalyst included. The other primers listed are 1 part primers so no catalyst required. Reducer is not included and if required, it must be purchased separately.

This sandable primer is commonly used on composite structures, and sometimes called "HI BUILD" primer. It can be applied and sanded down to fill small imperfections. Other epoxy primers we offer, are commonly used on metal structures, and not used to fill small imperfections.

Yes, the material can be used right out of the can, but it is recommended to be sprayed on. It can thinned with our Part # 09-00956 for a quart, or part # 09-00954 for a gallon.

Yes, the 2-part epoxy primers can be used on aluminum surfaces. Follow the pretreatment procedures for best results.

No. The zinc chromate is a single component primer. The packaging quantity does not affect that.

The zinc-chromate from PTI is manufactured to this specification, but off the shelf stock will not have this listed on the label or certificate of conformance. If you require the material to be identified to meet this specification, please request a manufacturer certs at the time of order. PTI does have an extra charge for this, and will be special ordered from them, to include this information.

This will come with the catalyst. You will need to purchase the PTI 1045 for the acid etch thinner.

This primer comes ready without having to mix a catalyst (2nd part) with it. You can use the 1022X66 solvent blend to reduce the primer to be used in a spray gun.

You will want to consult with your painter on this, but we always recommend using the same brand system from prep to top coat when available. Randolph offers a white and a white(Epibond) and dark green(Rand-O-Plate) epoxy primers.

This is a 16 oz aerosol can.

Per the data sheet on the web page for the PTI Waterborne Epoxy Primer, the estimated coverage is 800 square feet per gallon, so 200 sq ft is the estimated coverage for a quart of this material.

The tech data sheet does not recommend sanding between coats. They call for a light fog/tack coat followed by one full coat.

PTI Epoxy Primer is not offered in Aerosol.
