Abstract
Coatings are stripped from substrates by means of a stripping composition which comprises at least one low vapor pressure solvent. The stripping compound is applied to a coated surface of the substrate and is allowed to dwell in contact with the coating. The coating and stripping compound are removed, separately or together, and the stripping compound is reused to strip the same or a different substrate.
Claims10
A process for stripping a coating from a surface, the process comprising the steps of
- A. applying a stripping compound to a surface of a substrate, the surface having a coating be removed, such that the applied stripping compound overlies and contacts at least some of the coating to be removed, wherein the stripping compound comprises at least one low vapor pressure solvent;
- B. allowing the stripping compound to dwell in contact with the coating for a period of time sufficient to at least partially dissolve the coating;
- C. removing the stripping compound from the surface;
- D. removing at least some of the coating which was contacted by the stripping compound;
- and,
- E. repeating steps A through D at least once wherein the stripping compound of repeated step A comprises at least some of the stripping compound removed in a previous step C,
- wherein step D is conducted simultaneous with armor subsequent to step C.
