Can this be used on aluminum too? Since it doesn't rust

Yes it can used. But for Aluminium it is advisable to choose from 2K range of Samurai Kurobushi products as 2K based products are chemical resistant, have high adhesion strength to the surface, Waterproof, Scratch and weather resistant - Overall they are much more durable and long lasting.

can i use this primer to quote bike alloy wheel before applying actual paint?

If the alloy or metal is rusted then use UCU19 as it acts as a rust protective layer else you can directly use 2K04 Epoxy primer grey and do the paint.

Does this leech into water and affect any plants in touch with that water?

No It will not leech in water. As it is solvent based waterproof primer.
