Buy a smal amount of epoxy and just coat them. After about 3-6 months the plastic will Crack and it's bad for your reef when the magnet oxidizes. Silicone for mold making would work to or 100% pure silicone caulk.

I would feel uneasy about encasing potentially harmful additives myself, just because of the much higher margin of error. These magnets are covered in polypropylene and I've had about a dozen on the wet side of my system for about 3 years now, with no signs of bubbling or cracking.
