Heating & Powder Painting Indoors

[ipt]

I've seen lots of topics on melting indoors, haven't seen too much on painting indoors.

 

What are the dangers of heating jig heads with a heat gun and applying powder paint indoors? with no ventilation?

The powder paint seems to sink in the air more than it rises and its supposed to be non toxic.

Can heating the jig heads up with the heat gun produce any harmful fumes? 

Also, what are the dangers of curing in a toaster oven indoors?

 

Thanks for the info.

I can only speak from my own experience and that is it is safe to do indoors as long as a few things are followed one being that it's probably not a good idea to let it burn as non toxic is very vague when discussing these types of issues, I have not experienced any fumes either by heating with a gun which I don't do often because of the inconsistent results. You are working with lead so again at the temps were talking about its safe but to overheat would pose some risk if not careful I would not for any reason use your household oven either the real one or the toaster oven, get yourself a dedicated unit for this purpose.

 

A respirator would be a good idea the painter type should suffice they make them for some solvent based products as well as particulate matter, you don't need the big honking units with charcoal in them unless you choose too which there is nothing wrong with if your that safety conscious. I would use some sort of box to put your fluid bed in if that's the route you go powder can be messy and you can capture some of it by doing, this for the most part powder paint is pretty heavy and does not float off to much.

I powder coat my jigs outside my garage, but cure them inside the garage in a toaster oven, and haven't noticed any smell.

I wouldn't do it the house.

I use a heat gun to head the head and dip, then cure in a small oven...

 

IMHO...

 

For the most part - powder painting heads is one of the "safer" things you can do compared to melting lead/plastisol, using solvents, aerosol paints, etc.  Most of your exposure will be if it burns (buring is bad no matter what you burn) or if the powder gets airbourne (as if using a fluidized bed) and even then - it's like being exposed to a very dusty area - some people have no issues, others like me are very sensitive to airbourne dust.

 

With that being said - simple precautions will go a long way.  Don't burn the powder when curing, wear a dust mask when using a fluidized bed and open a window if you can.  I wouldn't use a toaster that you plan to cook in later... buy a cheap one just for this purpose - not sure if it is even dangerous, but just doesn't seem prudent. 

 

All that I mentioned above is also proportional to how many heads your going to coat... if you're coating 50 heads a year for your own use, probably not too much to worry about even if you ignored all safety precautions - BUT DONT!!! LOL!!  If your coating hundreds or thousands of heads a year as in a small business... you should take steps to set things up right.

From all i've read and digested,powder paint seems non-toxic-That said

 

Here's a warning and cautions using powder paint from the Eastwwod site-

 

CAUTION

Read and understand all instructions and precautions before proceeding.
This unit uses high voltage as well as powder which may become
flammable under certain circumstances. Eastwood shall not be held liable
for consequences due to deliberate or unintentional misuse of this
product.

 

                               Flammability Hazard
 

Powder coating dust, like common household dust, when confined and
suspended in air, poses a fire and potential explosion hazard if
ignited. Good housekeeping, adequate ventilation, dust control and
isolation from potential ignition sources is required!

Sweep up unused powder from the floor. Do not vacuum unless the vacuum is equipped with an explosion-proof motor. Never smoke while powder coating. Do not apply powder coat near any source of ignition, e.g. open flames, sparks, etc. Use the same precautions that you would for liquid solvent based coatings. DO NOT USE A GAS OVEN!

the toaster oven is just for baits, i wont be using it to eat from. but it is in my kitchen.

 

my garage isnt heated at all, so its way too cold do work out there. ill be working out there once it warms up, but im just wondering about painting inside with the heatgun & lead.

 

powder paint has to be highly concentrated to explode from what i've read.

It's all about handling properly if you follow the basic proceedures you'll be good.

[mark poulson]

If you smell something, or see some smoke, stop.  Your nose and eyes are your best safety feature when it comes to painting and heating.

One great thing about powder painting is you don't have to fully cure the paint immediately after getting it on the head....

 

I heat one head at a time over my heat gun - in a couple seconds I can get the jig just hot enough to get the powder to stick well when I dip it - I then hang it up, and continue to the next jig. Once I have all the heads coated, I'll hang them all in my small oven, turn on the heat and cure them.  Sometimes it might be a couple days / a week before I have everything coated and put them in the oven... it doesn't make a difference if they sit there coated but uncured for an extended period as long as you don't really bang them around and chip the paint off.

 

With that being said... you could heat you heads with the gun, "dip" them, then once you have a reasonable day outside - bring it all outside and cure them.  Just a thought.  If you get the head just hot enough to "flow" the powder out but not clump it on heavy they are pretty durable - sometimes I throw them back in a box before curing if I don't want them hanging around for awhile (to avoid kids sticky fingers!!!)

 

I wouldn't try to cure a head fully with a heat gun.... for one you can't control the temp and this stuff takes 10-20 minutes to full cure which just isn't practical to try one by one.

i do alot of powdercoating in my shop ...i wear a dust mask when i spray but some powders do put of fumes ..non toxic they say lol ....but i would def not do it in the house because u dont wanna cook anything in the oven u  use for powder...i have been powdercoating for 7 years now and would highly recommend some typ of ventalation and def not do it in the house like slow fish says u cant get them cured properly with a heat gun and the good thing about powder is u dont have to cure it right away because its not really paint it is actually so u can let it flow out and cure at anythime 

actually pastic lol
