Tubeman Posted February 3, 2007 Report Share Posted February 3, 2007 I talked to Calhoun last week about a problem I have been having with my plastisol discolouring (turning brown) if its been in my production pot for a couple of hours. Paul told me about an additive they use to stabilize the plastisol so it could be heated for upwards of 8 hours !!! Now I dont know the exact name other than its a derived from Soy Bean oil. You only have to add 4 oz to 5 gallons. This is not the heat stabilizer that is used to offset the initial start up heating. I can tell you the stuff is magic, I have tested it with flouresent colours and it works great. Today we are going to test it out in tube plastisol for a run of Pearl White...a colour that will reveil any plastisol discolouration very quickly. I'll post my results later on today, keep your fingers crossed. Quote Link to comment Share on other sites More sharing options...
BassnG3 Posted February 4, 2007 Report Share Posted February 4, 2007 sounds good have they figured out the bubble problem? I've been away for a while and was wondering. I still have about two gallons left over in a 5 gallon pail that nearly foams when heated:mad:. Scott Quote Link to comment Share on other sites More sharing options...
Garneau Baits Posted February 6, 2007 Report Share Posted February 6, 2007 Tubeman, How did the pearl pour go? Did you get the bubble cure chemical from Calhoun? If so how much do you use? I used 3oz per gal, It seemed to work for the most part but I still get a few bubbles, nothing like the FROTH syndrome though. As far as the color changing in the production pot, I use the LC 5 gal Pressurized pot. When I have plastic in it a long time I get a greenish oily residue that comes out the top of the hood where the mixing rod goes through it. I found out the oily residue doesn't only come out the top but it drips from the top inside of the hood and back into the plastic which after awhile changes the color of your plastic. I haven't talked with LC or Calhoun about this yet. I really think the only way to not have the plastic change color is to get it out of the pot as fast as possible which means using lots of molds. PS: I need more molds Del LOL Quote Link to comment Share on other sites More sharing options...
Delw Posted February 6, 2007 Report Share Posted February 6, 2007 The problem tubeman is talking about is a problem in ALL plastics when you have them in heat for that amount of time. like 45mins + it has nothing to do with bubbles. Normally you put in a heat stabilizer so your plastic doesnt scorch, this stuff is just better than heat stabilizer its not needed for guys who dont run thier pots all day with teh same batch of plastic in it. Mike runs big pots with a few gallons in each f I remember correctly.. Heat stabilizers burn off very quickly, Calhoun use's more heat stabilizers than all the other plastics thats why it can withstand more heat. The bubbles have been resolved months and months ago, we gone through many differnt shipments since then Quote Link to comment Share on other sites More sharing options...
Tubeman Posted February 7, 2007 Author Report Share Posted February 7, 2007 Hey Guys, sorry about the late reply...burnt out from too much pouring lately. Yes the White Pearl was a success !! The stuff is incredible for stabilizing plastisol over long periods of time. As Del said. its got nothing to do with bubbles. If you are using mixer with your production pot, any bubbles created for any reason will evaporate within 10-15 minutes anyway. Quote Link to comment Share on other sites More sharing options...
Tubeman Posted February 7, 2007 Author Report Share Posted February 7, 2007 Ted, if have a lid on your pot....you will get oil condensation on the inside of it from the plasisol. That condensation will discolor and scorch more quickly that the plastisol. This is why I don't use lids on my pots anymore, I realize pressure pots are quicker though.

SwampBaits Posted February 7, 2007 Report Share Posted February 7, 2007 Thanks for the report Tubeman. Sounds like a great product! I assume it's priced about the same as Heat Stablizer? Quote Link to comment Share on other sites More sharing options...
