Any brand is very similar i assume. It is just normal silicone chaulk,  
which comes in a big "syringe". You should have that tool which presses  
the plunger, but i guess for paper coating you could do without.
I only tried with acid curing, and it worked great, but someone mentioned  
the acid that is produced during curing might harm the printer. So i  
bought neutral curing at the DIY store a few days ago, chose grey variey  
so it is well visible on paper and also the black toner on it is well  
visible. It costs about 5eur, a bit more than acid curing one at ~3eur.  
310ml that is i think, you can coat a huge amount of paper with that.

The whole point is this silicone has a slightly tacky surface (you can't  
slide anything over it), as opposed to papers for baking or label backing  
which have a very slick surface. This allows the toner to stay in place,  
but allows it to come off easily too.
