Group,

I have received the literature from the Aeropoxy people and in this
literature they DO NOT recommend direct contact between their laminating
resins and any fuel.  They cite two reasons, the first being room
temperature curing resins exhibit reduced resistance to fuels.  The second
reason is the formation of microfissures in the epoxy due to vibration
leading to drips and an overall reduction in structural integrity caused by
the additional chemical attack.  They are recommending a two part
polysulfide coating as the best solution.  I have worked with polysulfide
previously in my rubber formulating career.  It does have unusually good
chemical resistance.  For instance, it is the only polymer I know of that
gives resistnance to laquers.  I have contacted one of the manufacturers of
the coatings, Morton Chemical (now called Advanced Chemistry & Technology),
to see if they could provide me, if they have it, any fuel and alcohol/fuel
immersion data which I will share.  I also can provide a copy of Aeropoxy's
literature as well.  I am sure they won't mind publishing it as long as we
don't alter it.  The coatings are available in trowel-on and paint-on
versions.  I also have the tech literature on Morton's paint on version.
All can be made availabe to any who request.
