What adhesive to connect lexan to MDF?

DrewKaree:

I M-U-S-T glue lexan/plexi to MDF.  It's a "sandwich" I am making.  MDF-Lexan-MDF.  In that order.  I need to glue the three pieces together for a project.  

Does anyone know of an adhesive that will join the two materials, or can recommend one?  I've already tried a mock-up with Gorilla glue, but it expands as it dries, and it pressed the materials apart.  White glue or woodworking glue isn't strong enough.  Liquid nails is too thick no matter how thin I am able spread it.  I need the three pieces to be in contact with each other across the entire setup.

The problem is that on everything I've tried, the friggen MDF soaks up anything thin enough to work, and anything thick enough not to soak into the MDF is too thick to be able to press the "sandwich" together.

Only thing that comes to mind would be some sort of construction adhesive.  Not too sure on the thicknesses of the different kinds, but you may be able to get away with using one of those slotted or jagged putty knives like for tile work.  That's what I did to affix sheet metal to the solid panels of my ddr hardpad.

BTW, what's this for?  I can't think of anything that would require a sandwich like that...

Tilzs:

I don't know if it'll work or not but you might want to look at some contact adhesive like what is used to glue down laminate.

Witchboard:

I don't know if it will stick to the lexan, but you could try liquid nails?

DeathDealer:

have you tryed contact cement??
When I use it, it seems to stick to everything.  You just put a coat on the wood and a coat on the plexi, let it dry a little and it should stick
