I can't seem to find an equation of some sort where a metal has a plastic coating over it causing a reaction?

This is so that the metal doesn't end up being oxidised, but can't seem to find any?

Maybe you are looking for Anodising ... http://en.wikipedia.org/wiki/Anodising

Its something along those lines, put i'm looking for the name of the plastic. For example garden chairs are often made from iron and then coated in plastic to prevent oxygen reacting with the metal. But what is that plastic exactly?

paint / varnish / sealant ?

[in anodising the oxide layer, which is harder than the metal, is made thicker, and then a sealant can be applied ]

Oh aye, so it can be any type of paint or sealant? I dont know which type of paint to use as I have to construct that in the equation with the iron you see, which is why I'm trying to find out what its called.

What you are looking for may be a procedure known as 'Powder Coating'.

It involves bonding a powdered plastic to a material (usually.. maybe always.. a metal.... not sure off the top of my head) by coating it with powder than heating it and bonding the coating to the metal.  Have a look... put Powder Coating into your favorite search engine, and see what you get.
