Following the MC application, an ambient flash is employed to remove excess volatiles from the coating prior to baking. The entire coating system is baked simultaneously in a single bake, as described in 3.3.4.

Remarks.

Validation testing for plant specific layering, ancillary materials, and processing shall be conducted prior to release.
