Abstract
This invention relates generally to methods for removing adherent materials, for example, paint, flashes, burrs, photoresists, contaminants, and other materials from various external surfaces. In particular, the method employs an improved media comprising core/shell particles. The media can be propelled against or along the surface by a gaseous or liquid carrier medium or a mixture of gas and liquid to remove the unwanted surface material. In one embodiment, suitable blasting equipment propels the media, via a pressurized air stream, against a surface of an object, for example an airplane skin, to dislodge the material to be removed.
