Anyone know of the best clear sealer for particle board?

I have finished cutting all the peices for a drill press table kit
I got from Woodsmith store. The main table top peice being
3/4" plywood. This MDF is sealed in a thin white formica
coating but the edges (end-flats), I suspect, can become flaky
over time of use, wouldn't want it to even start. The MDF
was free from my adult ed. class luckily. Any suggestions?
