Re: Delamination and Acetone

I have said it before, and I will say it again--Acetone is not suitable for cleaning surfaces prior to bonding.

Methylene Chloride or Dichloromethane is the only solvent this chemist would use. Go into the archives and read up on the glass plate test.

I know Boeing now uses Methyl Ethyl Ketone  (MEK) lacquer thinner or some such solvent, but MeCl2 is superior in all respects.  My personal opinion of the claim that it is carcinogenic is that some idiot in the government is blowing smoke up our heinnies.

I find it amusing that builders who are scared of using MeCl2 are feeding their children food with brightly colored food dyes--now, if you want to your family safe from carcinogens and brain-altering chemicals, stop buying all that colored breakfast cereals and Fruit Loops, etc which are causing a pandemic of ADD and other three and four lettered brain disorders among our society.

The bottom line is that if you have linear delamination the cause may be the cleaning solvent.  You did check for missed patches of polyester mold release before you rebonded it?
