It originated at Lockheed in the 70’s when a coatings engineer, Calvin Fong, was researching ways to rejuvenate aircraft primer. The technology was introduced commercially in 1987.
It is a process in which particles of solid carbon dioxide (dry ice) are propelled with high velocity air (usually 80-100 psi) to impact and clean a surface.
It is made from liquid carbon dioxide. CO2 exists as a liquid only under high pressure. When it drops to ambient pressure (the normal pressure that surrounds us), approximately half turns to gas and half turns to solid. The solid, usually in the form of fluffy snow, is then compressed to form dry ice blocks, pellets or nuggets.
It is frozen carbon dioxide (CO2). Carbon Dioxide is a gas which is natural to our atmosphere. It is inert. It is non-conducive. Nearly all dry ice that is used in dry ice blasting is recycled from factories and industrial processing.
