This new development is quickly expanding worldwide. The system uses small rice size pellets of dry ice shooting them out of a jet nozzle with compressed air. It works like sandblasting or high-pressure water or steam blasting, with superior results. The frigid temperature (-109.3°F) of the dry ice "blasting" against the material to be removed, causes it to shrink and lose adhesion from its sub surface. Additionally when some of of dry ice penetrates through the material to be removed, it comes in contact with the underlying surface. The warmer sub surface causes the dry ice to convert back into carbon dioxide gas. The gas has 800 times greater volume and expands behind the material speeding up its removal. Paint, oil, grease, asphalt, tar, decals, soot, dirt, ink, resins, and adhesives are some of the materials removed by this procedure. Only the removed material must be disposed of.
Dry Ice Blasting has been approved by the EPA, FDA and the USDA.
