Not all epoxy primer has isocyanate, correct?

[myredracer]

Went to a local bodyshop supplier a few days ago to get some epoxy primer. When I asked if theirs had any isocyanate in it they said any catalyst for epoxy primer has it. I'm positive this is wrong. Maybe only the stuff they sell does? The only other supplier nearby, White & Peters (used to be THE place to go to) only sells to body shops now. Haven't looked for other sources in my area yet.

Not that it matters, but I want to brush this on a driveway gate I'm building. (Could spray it but want a brushed on look to it). Any left over will be used on a couple of cars I'm restoring and I'd buy more of the same brand when needed. Or if I end up getting the gate powder coated, I want isocyanate-free primer for the cars anyway.

Maybe I should just order it online? I buy stuff online in the US all the time so that's not a concern. Any recommended brands that don't have isocyanate?

Thanks!

SPI to my knowledge has NO isocyantes in their epoxy primer, we use it all the time and on occasion brush or roll it on. They will ship anywhere in US at no charge, so if you have a US shipping address just south of you, shipping is free.. Here the tech sheet on it, you do need temps greater than 65* for the components to crosslink.

I had a big discussion with the 3M safety products guy about isocyanates and repirators, etc. He said brushing does not create enough fumes to be a problem. As far as respirators go, isocyanates are odorless but other components in the paint are not. If you can smell them through a respirator you are breathing isocyanates. A P95 filter should be OK for one use if spraying, according to him. Not needed for brushing but it couldn't hurt. The pros use outside air, a mask connected to an air pump outside the work area.

Thx for the info. I do have a full face respirator and some P95 filters. I'd be doing the work outside too, providing we actually get some sunshine this summer. I wouldn't mind having an ambient air pump but they are just so pricey. I'm going to look at ordering some SPI primer.

Spraymax high build epoxy 2k primer has no iso's

these are the spray bomb cans that have a bladder inside... before using, you push a button on the bottom to break the bladder and mix the 2 parts inside the can. They spray much better than a 'normal' spray can -- nearly as good as an HVLP gun. You must use it up within 5 days or so or it will harden, though.

I had great luck with this on a recent milling machine restoration. Still need a respirator to keep epoxy from blocking up your lungs, but no iso's means it's a much safer paint to spray than 'normal' 2k iso paints.

I have a can of Spraymax that's been sitting on the shelf for around 6 months and forgot about it! I've often needed to spray a small area before welding in a patch panel or replacement panel and most of the can would get wasted. I like the idea of being able to mix a small batch by hand and then brushing it on. For the gate I'll be starting soon, maybe the Spraymax in a can would be the way to go. And it's only a driveway gate, not a valuable car resto.

I saw something about a home built one using a war surplus gas mask and I just don't remember what was used for an air pump. I guess you could google it.

I've googled every which way possible and have searched ebay and CL high and low and it comes down to if doing it the safe and correct way, there is no low-cost solution. Some have used a basic oil-less pancake compressor or even a shop-vac but that's not something I'd ever do. The respirator is the easy part.

No epoxy primer contains Isocyanate. People often get epoxy and 2K urethane confused which does require an Isocyanate as a catalyst. Epoxy works on a completely different equation and generally will not disturb substrates.

The Hobbyair supplied-air respirators start at around $400.

For info about what is in the paint you are using, search for the MSDS sheets..... should be on the manufacturers webpage.
