... such as primers and can coatings. Their main advantages are that they have no hydrolyzable bonds (and are thus completely resistant to hydrolysis, or swelling by water) and they have very good adhesion properties. They also resist swelling in the presence of oils. However, they turn yellowish-brown during baking...
