Gloomisman Posted January 30, 2009 Report Share Posted January 30, 2009 Last night I went to start powder painting some of my jigheads. Well some how some way my black powder is not fluffy like it use to be. I use to put it in my fluid bed and it would work better then my brown and gp. Now it doesnt fluff as gay as that sounds. Is there any way to pull out the moisture. When I use to open the can I would get the dust like draft out of it like flower or anything else ganulated. I do have a dehumidifier. I have been thinking of opening it up and putting it in front of it. or maybe set the oven on 100 deg and try to dry it. I'm affraid of that one though. Might end up with a big glob. Sifter maybe?? Any ideas? Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted January 30, 2009 Report Share Posted January 30, 2009 (edited) Salt is good for absorbing moisture. Heat up a pound of salt in the oven, to dry it out. Place the powder and salt (separate containers) in a sealed container (tupawear or similar) for a week or so (just guessing). stir it up twice a day. It should do the job. I think there are other crystals that do the job faster, but cannot remember the name, sodium something. Try a web search. This is from wikipedia: Deliquescent materials are substances (mostly salts) that have a strong affinity for moisture and will absorb relatively large amounts of water from the atmosphere if exposed to it, forming a liquid solution. Deliquescent salts include calcium chloride, magnesium chloride, zinc chloride, potassium carbonate, carnallite, ferric ammonium citrate, potassium hydroxide and sodium hydroxide. Due to their very high affinity for water, these substances are often used as desiccants, which is also an application for concentrated sulfuric and phosphoric acids. These compounds are used in the chemical industry to remove the water produced by chemical reactions, to increase the yields. In everyday life people are most likely to come across deliquescence when they spill some instant coffee. This turns from a dry powder to sticky liquid when exposed to air for a few hours.

cadman Posted February 1, 2009 Report Share Posted February 1, 2009 thanks. I'll get some silica packs and do that. Thanks alot Vodkaman I was going to recommend the silica packs. You can even put the silica packs in the powder, to keep it drier. Make sure the silica packs are clean if you intend on putting them in the powder. One last thing do not put your powder in the oven or anything really warm. This will active the bonding process of the powder. 100 degrees may not be much, but it could affect adhisiveness down the road. Quote Link to comment Share on other sites More sharing options...
