The plastic media covered by this specification is intended as an abrasive blasting material for paint removal. The visual appearance of surfaces stripped using this media can vary from no discernible effect to extensive erosion damage. Other damage may occur which is not visually apparent, but which may be manifested as loss of fatigue life. Those effects are dependent on the nature of the substrate, plastic media used, type and degree of contamination of recycled media, nozzle pressure, angle of impingement and distance of blast nozzle from the work. Prior to the use of these media for production blasting, appropriate engineering studies shall be initiated to determine the effect of the process and the media on the substrate. Surface residue can result from the use of any plastic media and should be removed prior to refinishing. Type V residues must be removed using methyl ethyl ketone or similar solvent. Type I, II, III, IV and VI residues can be removed using a detergent wash.
