Chemically Bonds to Aluminum & Steel for a Corrosion-Resistant Base
Zinc phosphate promotes adhesion and corrosion resistance. It bonds to aluminum and ferrous metals to create a uniform, paint‑ready base for your topcoat. The result is reliable adhesion and long‑term corrosion protection when used over properly prepared substrates. It is especially recommended for aluminum and also adheres well to properly prepared steel and bare wood.

Question
Dan Miller –
I use the Seymour green zinc phosphate primer on both Aluminum and Stainless diamond plate panels.
1. How long do i need to wait between the first coat and recoat?
1b. Do I need 2 coats?
2. After the 2nd coat, can I heat in paint oven to speed full cure? At what temperature and for how long?
3. Is there a time window after the primer cures before I apply, in this case, Durabak textured coating? In other words, do I need to wait a minimum time of 24 hours and a maximum of 72 at room temperature? Or if heated at 125°F, minimum of 2 hours, no maximum before textured coating?
3b. If I heat in paint oven, does that time change?
Thanks,
DM

Answer
Seymour Paint –
You only need one medium coat, and it doesn’t have to be a full hide. If you want to do 2 coats please wait 10 minutes. Multiple coats will extend the cure time, but you can accelerate the cure by warming the primer. Do not exceed 140F. I don’t have exact times for drying/curing as there are variables with temperature/humidity/paint thickness.

15 square feet. It’s only 12 ounces and you have to account for overspray.

Jeff in RI –
I want to use Hi-Tech Engine Enamel Spray Paint—AMC Blue Metallic to paint the heat exchanger for a diesel engine on a sailboat. It’s a separate unit, not integral with the engine. It is made out of copper and copper alloy. Approx 3″ diameter and 18″ long. Is 16-897 Seymour Zinc Phosphate Primer the primer you would recommend? If not, what should I use?

Answer
Seymour Paint –
Yes, that is the correct primer. Apply 2 light coats, no more, and make sure to allow 48 hours to cure before top coating as it’s a slow dry.

Answer
Seymour Paint –
The most important thing is cleaning and prepping the surface first. Remove all loose dirt and debris. If the surface has rust, old paint or a rough surface use sandpaper to smooth out imperfections and improve the paint adhesion.

Rust, unless completely removed or neutralized with an acid converter, will creep under coatings. This appears to be the case here.
