ABSTRACT:
The present invention relates to a process for removing a protective coating from a surface of an airfoil which process comprises the steps of providing an airfoil having a protective coating to be removed and critical areas which require protection during a coating removal step and masking these critical areas by applying an ultraviolet curable masking material to the critical areas of the airfoil. The process of the present invention further comprises the steps of curing the UV curable masking material using ultraviolet radiation and stripping the protective coating from unmasked portions of the airfoil.
