Is New auto paint in California water based?

We can only hope that today's waterborne paints are better than gm's early-70s "experiment" with them was.


CA is concerned/obsessed with VOCs. Shut down their statehouse and a lot of their VOC issues might possibly go away. Or is hot air considered to be a volatile organic compound?

I just called my local auto paint jobber and got a clerk who really knows his auto paint.  In Calif. they don't sell the old acrylic enamel anymore.  He said most new cars and new car repairs are painted with the new water based paint.  But you can still buy solvent based paint and urethanes.  The solvent that is used is a blend of acetone and PCBTF.  They still sell the isocyanate catalyst for this paint, which is required.  I asked doesn't the isocyanate hardener violate the Calif. VOC laws.  He said no.  Isocyanates if used improperly will kill you, but not the trees, and that's fine with Calif.  So they recommend an air supplied mask to use it.  Also they still sell epoxy primers.  they also sell the old lacquer primers.  



If you don't know what PCBTF is, here is part of an article on it from the Internet.


PCBTF — also known as Oxsol 100, Parachlorobenzotrifluoride and p-Chloro-a,a,a-trifluorotoluene — is the most widely used solvent in the coatings and adhesives industry. PCBTF is used in field applied architectural and industrial Maintenance (AIM) coatings; marine coatings; auto-refinish coatings; factory-applied metal, plastic, and wood coatings; and in adhesives and consumer products, including paint thinners.

The extensive use of PCBTF in industry products is largely because, in 1994, the U.S. Environmental Protection Agency (EPA) exempted PCBTF from its list of Volatile Organic Compounds (VOCs). In addition, PCBTF has more favorable characteristics than other exempt compounds, for example it evaporates slower and has a higher flash point and therefore is less flammable than exempt VOCs including acetone.
