Method for removing a selenium layer from a substrate
摘要:
A coating layer, such as a photosensitive selenium coating is removed from a substrate by producing cracks in the layer, introducing a volume expansive material into the cracks, and then causing the volume expansive material introduced into the cracks to expand and thereby dislodge the coating layer from the substrate.
