Flame Treating

What is the name of the Chemical thaqt supposedly takes the place of Flame treating? I know there is one, I just can't think of the name of it.

True...on the surface. But the thing is that the mold release agent isn't only on the surface of the part. It's mixed in with the molten plastic before it's molded. Heat brings it to the surface, thus the flame treating to remove it. These chemical agents may remove it from the surface, but how can they wick it out of the plastic itself? It may pass an adhesion test today, but what about after the hard hat or other part is subjected to heat down the line and more release agent makes it's way to the surface under your paint? It's why flame treating takes several passes, cleaning with alcohol between each pass. It keeps coming to the surface. You flame treat until it stops coming back up.
I've still yet to see someone do a thorough test on anything. Not even flame testing then leaving it in the sun. I'm going to have to set up a test. Guess I'm going to be picking up some hardhats next time I'm at Lowe's. LOL! I'll start a separate discussion and I would love some input on how to set it up and which products to test. I figure beginning of summer is a perfect time so I can leave stuff out in the sun. Stay tuned.
