  • Cryogenic mechanical means of paint removal
    Patent number: 5044129
    Abstract: A method for cryogenic removal of paint and other surface coatings is disclosed. Alternate stream pulses of a cryogenic fluid and abrasive beads are directed at a surface coating to alternately embrittle and then shatter the coating. The pulse durations and the time intervals between pulses are generally less than one second and may be on the order of micro and milliseconds. The cryogenic stream pulses may also be alternated with other mechanical paint removal methods.
