Re: What is the chemical make-up of correction fluid (white out)?

Correction fluid such as "White-out" is a suspension of opaque particles,
usually titanium dioxide, in a volatile solvent, usually mineral spirits,
trichloroethane, or methylcyclohexane.  There are also varieties that are
water-based, although they often contain some alcohol.

[Depending on the solvent system used, there will also be a solvent or water 
soluble binder or 'glue' used to permanently attach the TiO2 to the paper 
surface...Eds. note]

What is correction fluid?  In short, it's just quick-drying paint, nothing
more.  I do not know who patented it originally, but the idea no doubt
came from someone who thought, "I'll bet if I put a little white paint 
down on that extra letter, nobody will know the difference!"
