Why aluminum paint?
I have a can of aluminum paint. I have it because it was left by the previous owner of my house. I've never used it and I'm wondering if there is something that it is good for. It must be good for something or they wouldn't make it. What is that? I did Google it and got inconclusive answers. E.g., it's durable, but a lot of paints are durable. Thanks, Bob |

: I did Google it and got inconclusive answers. E.g., it's durable, but a lot of paints are durable. The primary reason it was first made (besides the 'fake metal' look) was because originally, paints were made with natural drying oil vehicles (varnishes-- tung, linseed) which were VERY suseptible to UV damage by sunlight. Aluminum, better than any other pigment available, positively blocked the UV. It also looks nice, to paint a piece of metal that _should_be_ silvery, but's all corroded, and get it back to looking like clean(ish) metal again. LLoyd |

Well, that's a good enough reason to have a can around. Bleed through drives me crazy. I usually treat the knots with 2 coats of shellac, a coat of Kilz, then prime & top coat. And cross my fingers. Thanks for the tip, Bob Old time house painters would use a coat of silver to cover very dark color of paint when they wanted to paint over with a lighter color. The aluminum has superior coverage and a neutral shade. Paul K. Dickman |

But there is also something to beware of with that -- and something which is likely to happen given how long it has been sitting in your house. *Don't* put it in one of those paint shakers to get it stirred up and properly mixed. A friend worked for a while in a hardware store, and someone else put a can in the paint shaker (ignoring the warning labels to not do that on the shaker) and after a few minutes the can blew up, spraying the hot aluminum paint all over the store. :-) Apparently, the friction of the flakes of aluminum developed a lot of heat compared to other pigments. And maybe, once it got hot enough, the pigment and the vehicle may have reacted together. Stirring an open can with a bent shaft in an electric drill apparently does not generate anything like this amount of heat, so you can do that.

: Apparently, the friction of the flakes of aluminum developed a lot of heat compared to other pigments. And maybe, once it got hot enough, the pigment and the vehicle may have reacted together. Actually, that's not a problem with a full can, nor particularly with modern synthetic vehicles. Boiled linseed oil and boiled tung oil are "drying oils". That's a misnomer, because what they actually do is not 'dry', but 'cure' with the oxygen in the air, once exposed. The only thing that dries in that sort of paint is the extra solvent added to get it to proper consistency for brushing or spraying. To that end, as the oils oxidize they do *(like any other material that's oxidizing)* liberate heat. In a full can of paint, there's not enough free oxygen to particularly warm up a can, and most of it has already been consumed just sitting on the shelf, anyway. The same is true of a partial can that has been sitting for a long while. However, I don't know anyone who wouldn't first (almost compulsively) open a can before using it -- even before shaking it. You just HAVE to look! (sure... to check it's not skinned over, still good, how much... natch). And when you do that, you refresh the oxygen load in the can. NOW when you shake it, you may have a small amount of the drying oil and a large amount of air. Shake it, and you literally aerate the oil, encouraging a rapid, heat-generating reaction. If you get that mass hot enough, you volatilize the solvents, raising the pressure in the can significantly. Worse, because the solvents are dissolved in the oils, when you remove the lid, they may boil off (flash off) from solution, causing the whole contents to erupt from the can. It's not the aluminum. In fact, if anything, the aluminum would be competing with the oil for the oxygen... but generally doesn't oxidize much, because it's slower to react, and because as soon as it develops an oxide skin, it inerts itself. That said, add water to the mix, and all bets are off. Water, aluminum, and a higher-than-neutral pH can cause some vigorous reactions. Lloyd |

Paints and oils shouldn't be shaken just prior to application, but I've never felt any temperature rise from shaking a can of anything. I suppose it's possible, but you couldn't prove it by me. For the catalyzing finishes, I always float argon on the top to eliminate the problem of skinning. Yet another reason to have a little TIG around the shop, wot? It's not the aluminum.

: Since the propellant of choice seems to be propane nowadays, I wouldn't be too sure of the safety, Lloyd. non-sequitor, Larry... we're talking about open bulk cans of paint, not spray cans, which NEVER get any free oxygen in them, til you puncture them for disposal. Yes, oil paints should not be shaken JUST prior to application, but shaking is just fine, so long as you let them de-gas before use, AND you verify there was no 'skin' in the can before you shake (lest little crumbs of that get dispersed into the finish). Flooding a partial can with inert gas before hammering on the lid is a good way to help prevent that. Neither have I had any paints heat from shaking, but it is possible with a natural vehicle paint, it's just not the aluminum causing the problem; it could happen with any linseed or tung oil paints. As you mentioned, your rags are evidence of that. Lloyd |

And, just to make it clear--that doesn't mean weren't looking for ways to prevent such accidents; only that those types of initiating events were in others' purview, not mine so my research concentrated on those events that were criticality events foremost. If we did happen to come across some scenario in our areas would give the ideas to the others for evaluation, of course, but each group concentrated primarily upon their own field for initiating events and the facility operation plan was a then an amalgam for all. -- |

There's nothing on the cans about not shaking. I've not used a lot but did a little touchup with one a few years ago. AFAICT they're still as good as new despite the age as far as appearance in can and behavior in use goes. I didn't drive to town to put one on the paint-store shaker but I did put it on the homebrew vibrator I've cobbled together here out of an old combine pittman sickle drive. It's not as fast and has a longer stroke compared to real shaker but does get the stuff off the bottom...I don't remember noticing any pressure after that when opening it (but then again I wasn't looking for any as had never heard the stories/warnings). I don't know if there is more than one type of Al paint where there's a significant difference in the makeup or not. I'd guess these go back to around the late '70s/early '80s -- from the stuff in the old wellhouse it looks like Dad bought out a bunch of the stock from the Co-op when it closed the retail store in town but I'm not sure just when that was altho it's been quite a long time ago now...I looked but didn't see anything on the can that indicated a date -- even a tm or c on the label printing. There's a manufacturer's mark which likely has a date in it but it's coded to where can't decipher which letter/number(s) might be a year. I'd like to see a real explanation--a quick search on manufacturers' sites didn't bring anything to light. -- |

Look... it takes little heating to raise the vapor pressure of some of the higher-fraction solvents in there to the point of flashing when the can opens. It doesn't necessarily require a violent chemical reaction, nor long sitting in the sun to raise the temperature to the point where that could happen. Still, it's a long stretch from a 'poof' of vapors from the can to an 'explosion' of aluminum paint boiling out of the can. Lloyd |
