[AT] Acrylic enamel paint hardner????

[Louis Spiegelberg]

Charlie,

There is quite a difference between automotive and industrial paint.  They
are formulated for different applications.  Hardener has been around for
years for automotive paint.  If you go to a NAPA that sells paint, they
should be able to get you hardener for paint.  There is a difference between
hardener for synthetic (alkyd) and acrylic enamels.  I ran short of hardener
one day for synthetic, so I figured that I could use hardener for acrylic.
The normal pot life is 4 hours.  I sprayed my first coat of paint.  I came
back a few minutes later to shoot my second coat.  The paint had all gelled
in my gun by that time. What a mess to clean up.

Hardener adds durability, gloss, and color hold out to the paint.  It also
helps it cure quicker.

Here is what makes me interested in this topic.   I've read enough accounts 
from folks on the list that I'm certain that using hardner with plain old 
enamel paint can be done.  The knowledge of this list is testiment to that. 
However, I've been involved with industrial painting projects for over 20 
years.  I've used all kinds of exotic epoxies, urethanes, acrylics, vinyls, 
etc. and I've never seen or heard of (except on this list) anyone using 
hardner with an enamel.

When I first saw it mentioned on the list I asked a friend/business partner 
who has been and industrial painter since he got out of high school in the 
early 60's and now owns his own company.
He had never heard of anyone doing it.  I asked one of the industrial reps 
for ICI Devoe coatings and he had never heard of it.

All of this just seems strange to me.  It leads me to believe that somewhere

out in the heartland someone just decided to try it and lo and behold it 
worked.

I sure would like to know how.  I have to agree with one of the other posts.

The hardner is probably in fact a plastic and the enamel paint just becomes 
the colorant and body of the home made epoxy that results from the mixture. 
I'd be interested to see some of this paint tested along side other 2 
component paints to see how it holds up in terms of gloss retention and film

degredation.

Does anyone know of a manufacturer that makes a hardener specifically for 
enamel paint and comes as a kit?
