Tire sealants available in the EU?

I know Slime is available, both in the tube and tubeless variety, where in Slovakia at least, the tube variety is less expensive than tubeless. But I've read about some pink tire seal and other types, so I wonder if any members in the EU know of other brands that are available and possibly cheaper while still being effective, if not superior to Slime.

I have had good experience with Slime-- tubeless version -- sealing up random thorn punctures in tubed tires. I suppose the tubeless version is just higher quality than the tube version, as it must run in tires at high speeds.

The two tires of one cutter bar mower I've just sent off to get foam filled, but I really can't afford foam filling larger tires that I have.
