Dry ice blasting alone will remove any loosely adhered rust, surface rust, oxidation, and salts (SP 6), but it will not remove the deeply adhered or pitted oxidation. Due to the non-abrasive characteristics of dry ice, it is not aggressive enough to create a profile or a white metal finish.
Our new dry ice blasting + abrasive solution, the E-CO2 150, adds an abrasive to the dry ice blasting stream. The solution boosts its’ aggression and effectively removes deeply pitted rust and corrosion, while eliminating the issues with traditional methods of removal, such as excessive dust and waste. The solution achieves a white metal finish (SP 10 / SA 2.5 / NA 2).
