Re: MEK in paint

I passed the questions along to my father who is a retired chem
engineer, with some knowledge. His reply was:

My small bottle of poly ester resin catalyst is labled, "(MEK
PEROXIDE)"
DANGER - CAUSES SEVEERE BURNS - MAY BE FATAL IF SWALLOWED. It comes
from CLEAR COTE CORP. in St Petersburg FL 33713. Contents 1.4 FL
OZ


He didn't comment on the polmerization potential.

Actually MEKP is Methyl Ethyl Ketone Peroxide, not phosphate. It is a
free radical initiator for polymerization of monomeric components
like styrene that is found in certain polyester resins. It may help
initiate cross-linking reactions in some alkyd paints, but I have no
direct knowlege of this.

Just a note that you folks might want to be careful of...

Seen much discussion about adding MEK to paint - may very well
work.

Be advised, however, that MEK is NOT the stuff used to catalyze
polyester resin. That's MEK_P_ (Methyl-Ethyl-Ketone Phosphate)

MEK is a cleaning agent (Methyl-Ethyl-Ketone). Think
"super-acetone"
and you've basically got it.

Now... I'm not a chemist, but I have a sneaky suspicion that the
original author meant MEKP, not MEK (MEK is relatively hard to
get, in the home market.) and after all... how far is polyester
resin
from polyester paint?

Perhaps he could comment?
