Manufacturing Sanding Discs w/o MEK

	I am working with a sanding disc manufacturer that uses a binder 
consisting primarily of MEK (methyl ethyl ketone) and ethyl acetate 
to bind the abrasive material to the paper/ cloth disc. The 
representative I spoke with said that this binder was standard 
throughout their industry and she has spoken to trade association 
representatives regarding alternatives and has found nothing.   The 
sanding discs this company manufactures are the ones available at any 
hardware store for commercial or residential applications.  
	I have searched the archives and some other websites with no leads 
regarding a more environmentally friendly alternative binder.   Does 
anyone have any ideas?
