Are Foam-iT! and FlexFoam-iT! "water-blown" foams or "solvent-blown" foams?

Article courtesy of Smooth-On, Inc.

Foam-iT! and FlexFoam-iT! castable foams are water-blown polyurethane foams that expand and cure quickly to solid, strong, lightweight foams. These types of foams are also known as "cold foam" because they do not require baking in an oven to cure. They are designed to be processed and cure at room temperature (73°F / 23°C).
