Ppg amercoat 370 review

[Rick D]

Ok so doing some more checking, 2.1 voc is your limit in Canada for primer (epoxy) looking at the Amercoat 370 it does sound like a great product and will most likely work for what you want todo with it.

Couple of things to watch for is your mil build. You can achieve 4-6 mils pre coat applied (that's ALOT per coat). So I would say if they have the reducer (Amercoat 65 xylene) get it and cut it up to 20% as recommended it will help a lot with air spraying it.

The other thing is you will need at least a 1.8 tip for your spray gun, so a primer gun is what you will need. If you try to spray it out of anything less then the (1.78 to be exact) it will go on very ruff and not be very smooth and possible leave areas that do not have enough coverage and could rust or corrode again.

Another thing to watch is your film thickness where you will be attaching new metal, if you end up with excessive film build in these areas you will have issues welding and possible panel alinement.

The last thing you need to make sure of which I could not find the anwser to was what other products "can" it be top coated with?? The product it goes with is Polyurethane, so if you top coat it with a polyurethane based product you will good but if you try to use a polyester base product you could have adhesion issues if it is not compatible with it.

Please do not take my explanation as you do not know what you are doing, I just try to explain things so anyone reading can understand

I hope this helps answer your question!!

Listen to Rick, he's got the back ground.

I can tell you we use Ameron products for our equipment. They work very well and are reasonable to apply. I especially like their primers and sealers. In situations where primered only parts are exposed to UV and the elements, it hold up very very well. We specifically use Ameron Amerlock 2. Just thought I'd give a bit of feedback.

thx for the info. My gun is a devilbiss 540 with 1.8 tips I think and I have the primer nozzle to match with. I appreciate all your advise but like I said I am limited with ppg and dupont and montana. I read some people use dp90 too, so I will take my time and continu the research to take the right primer.
