Hey all
just need to know if Im gonna have to buy a moisture trap to paint my chassis?

I'm using a heavy duty, 2-pac industrial protective
coating called barmastic.
Can I get away with not running a moisture trap in the line?

Also, what safety precautions should I be using with the 2-pac?

And generally how much thinners should I be using?

Sorry, I'm a bit of a newb to this painting business..

I'm not a spray painter but My Son is, and He has a water trap fitted to his compressor and it does fill with water and has to be emptied every now & then....
The air sucked into the compressor tank has moisture in it...

2 Pac... is fairly dangerous.... make sure You use a top of the line face mask & filters.... thats all i know....

Is it the fumes or the paint particles that make 2-pac dangerous?

both mate, 2-pac paints contain isocyanide which is nasty nasty stuff if breathed in .... make sure you use a good face mask and try not to get to much on yourself.... in small doses it should not be to harmfull but its not worth the risk... i am a painter by trade and have a friend who suffers from isocyanide poisioning and trust me its shitty to the max..... i always wear latex gloves when mixing the paints and when spray larger areas air fed masks with full protective suits.

you will also need a water trap as all compressers will put small amounts of water into the air lines..... it should be just after the compresser for best affect. U can also get ones that work as a secondry water trap that go inline with you spray gun. no where near as good as the proper ones and only give a small amout of protection but every bit helps...

steff...........................................

My Son will only use 2 pac in a proper spray booth....

I believe its one of the main reasons so many painters leave the profession and do something else....

dont tell me that

Do all 2-pack paints have isocyanide in them? There is no mention of it on the packaging.
The stuff I am using has a "Pack A" which contains the actual paint and a "Pack B" Which has the hardener in it.

What are the symptoms of isocyanide poisoning?

thanks heaps

One of the symptoms is death.....Make sure you use the correct epoxy reducer with the Barmastic or it will go "funny". Not all 2pac paints have isocyanide in them but always use the correct PPE.

you can buy ones that specify that they dont contain it

Well my reasoning is if they dont specify it on the label then it probably doesnt contain it.

I've read up all the MSDS sheets on Isocyanate and Isocyanate and it sounds pretty nasty.

And yes Mick I have the correct thinner

I would play it safe and assume it contains some bad stuff. They are not required to list what is in it on the label as it is a "chemical" intended for industrial use only and the warnings on the tin (avoid vapours and skin contact) suggest to me that it would not be part of a well balanced diet!! Just play it safe and wear your thongs upside down.:thumb

Dubcrazy: re putting the moisture trap just after the compresser, I always thought it was better to have a run of hose/pipe from the compresser to the trpa to allow the air to cool and therfore more vapour will condensate.

What do you think?

I painted my bus in 2pac, first 2pac epoxy primer then 2pac Glasurit.
I sprayed it in my garage and made a spray booth out of plastic drop sheets.
Before you open the paint put on a GOOD mask and always cover yourself up.
I used a paint coverall with a hood, eye googles and gloves, the bad shit can be absorbed through your skin and eyes.
I spoke to a number of painters before I started and this was what they use,.
It is the fumes that do the damage, if you are careful you should be O.K.

If you are just doing one vehicle it wont be a problem if you do the above, if you are doing it as a job, invest in air fed breathing gear,

Cheers

thats pretty much right murph, i have mine about 5 foot away from the compresser which is plenty enuf for the air to cool. Poeple tend to have them so far way sometimes it stops them being affective. U need to stop the moisture before it gets down the air lines not stop it at them end.

In a perfect world you will have your main trap close (5-10 feet) from the comresser and at the and of the fed another smaller mounted oil/water trap that you run your airline you are useing from....



steff............................

Thanks for the help people
I have a mate with an air trap so I should be sweet.
