What is the difference between epoxy-resin coated slides and teflon-coated slides?

Our epoxy-resin coating adheres on the glass very well and slides with that coating can be produced more cost-saving than slides bearing coatings of fluoropolymer for example "TeflonĀ®" (a trademark of DuPont). Normally the masks of fluoropolymer-coated microscope slides are more hydrophobic than those coated with epoxy-resin.
