HM-604 is a high sensitivity, water-washable fluorescent penetrant. It has been accepted and used by major aerospace firms – airframes, turbine engine, and missile – for several years. Approved under MIL-I-25135 and AMS-2644, HM-604 qualified to the stricter requirements of MIL-I-25135-D without modification.
