Dry Ice Blasting Division
Dry ice blasting is a non-destructive method of cleaning surfaces and removing unwanted coatings, grease, paint, and rust. We've taken your automotive detailing needs to the next level. Who knew your undercarriage and engine bays could look this good & have a fresh start?
But what does it do?
When dry ice particles are blasted at a surface, unwanted contaminants freeze and fracture through an explosion of energy. This results in the removal of unwanted coatings, grease, paint, and rust.
We blast surfaces clean using a combination of compressed air and dry ice particles at supersonic speeds, at temperatures of -78.5°C. The dry ice pellets create an explosive sublimation chain reaction which breaks the bond between the substrate and the contamination. The entire process happens in a matter of milliseconds. Crazy, hey?
Will this harm my vehicle?
Simply put, no. The process of using dry ice to clean surfaces is safer than that of water or other abrasive medias such as sand or glass.
Because dry ice is non-abrasive and turns back into gas after the reaction process, the surface is left clean with no secondary waste or damage.
Ok, I'm intrigued... what's the science behind it?
Well, there are three primary factors that contribute to the cleaning process:
1. Pellet Kinetic Energy - Occurs when the dry ice is accelerated by compressed air at supersonic speeds. When the dry ice collides with the substrate being cleaned, it creates a kinetic effect.
2. Thermal Shock Effect - The extreme temperatures cause a thermodynamic shock, which causes the contaminant to become brittle and shrink. The rapid transfer of heat into the dry ice creates an extreme temperature change resulting in micro-cracking of the contaminants, leading to the failure in the bond between the contaminant and the surface of the substrate.
3. Thermal-Kinetic Effect - The transition from a solid to a gas where the dry ice expands up to 800 times within a few milliseconds, lifting the contaminant off the substrate and causing a micro-explosion.
Are you geeking out as bad as I am?!
Why have I never heard of this before?
The concept of dry ice blasting is fairly new to the consumer automotive market and has traditionally in the past been used in industrial settings.
It seemed near impossible to find a undercarriage coating provider who would actually remove contaminants and then apply an undercoating protection, particularly on older vehicles. Our research showed that at most in other shops or dealerships, a pressure washed undercarriage followed by a coating would be applied... but... in typical beyond detailing fashion, this wasn't good enough for us. So Sub-0° was born.
