See link, see properties of the product <<<<<<<<< URETHANE
Yes, it has 'ceramic' powders added.........what ever the hell that means........
Duplicolor, which I use BTW, 1635, for incidentals and ease of application where and when I need a cheap and quick black paint.........is good up to 500 degrees. Well, guess what? so is your common automotive acrylic.
For wheels and such, when I need to 'push cure', I'll bake them in the oven at 350 degrees for 30-45 minutes after an overnight dry.
Here is my tractor, engine and frame were painted with urethane, and more than two years later.......good as new-
