About LinkBacksIs the dangerous part (cyanide etc) in the hardener? Only thing I can think of, cause i've been sanding and polishing all the orange peel out of the laquer without any mask!

Beep Beep while I slide up the street...msn addy - sam.barwick@ntlworld.complease DrIvE slowly
The isocyanate in the hardener reacts with the resin in the paint cross-linking and forming a complex structure. The isocyanate is effectively 'bound in' to the structure and so is no longer harmful. A bit over simplistic, but it should do. If you really want I might have a diagram of the chemical process somewhere!! lmao

lol nice one, it was just something that was bugging me : -] I get's ya

like salt is sodium chloride and when a chemicl reaction occurrs is harmless
Like anything really isn't it
Water in its two parts are poisonous (hydrogen + oxygen)
Sodium split into parts (chlorine + oxygen)

Mix sodium (salt) with water, run 2 carbon rods with about 10 - 12 volts DC through them and you get chlorine gas, and i'm pretty certain its oxygen or hydrogen. But definately chlorine gas. Which is, of course, poisonous (as i found out the hard way when i sniffed a vat of it in science)
Salt is Sodium Chloride. Water is Hydrogen and Oxygen.
Sodium is just sodium, hence the 'Eh?'

Here you go - isocyante/hydroxy resin cross linking:
