I spotted this photo yesterday on the "most viewed" so I thought there was a forum thread going on about this, but found nothing.

I guess nobody has asked yet, so what is this green coat on the A300's surface? Thanks in advance.

All you ever wanted to know about one particular type of green de-icing fluid - assuming that is the correct answer:

Looks like the old Eythel Glycol de-ice fluid, or the same stuff that you put in car radiators.

But that stuff AFAIK wasn't supposed to be used anymore because it tends to poison things.

I wasn't aware that colors of de-ice fluid had been standardized.

Actually the green stuff isn't "de-icing" its "anti-icing". The orange stuff is for de-icing. The green stuff sticks to the airframe longer therefore affording a much longer hold-over time.

The green anti-ice stuff is "type IV".

Looks like someone wasted a lot of type IV. It should be on the wings and empennage only. Hopefully they didn't use it for De-Icing- the surface must be cleaned with type I first, then Anti-Iced with type IV.

Normally, anti-ice/de-ice fluid will "wash" off during take-off.

Here is one interesting link for those who want to dig a little deeper in the stuff: http://www.aea.be/aeawebsite/datafiles/AEAtrainman_v1_final.pdf

Ethylene Glycol De/Anti-Ice Fluids remain in use, however it is not used as much because of environmental concerns. As far as I Know, the Isopropyl Alchohol/ethylene mixture (Type II) is no longer in use commercially.
The modern De-ice fluids consist of Propylene Glycol, with type I typically a low viscosity fluid that is mixed with water, then heated to 170- 180 degrees F to melt snow and ice. it is orange in color.
Type IV is used full strength, and has a thickening agent to allow it to stick to the aircraft surfaces. It is green in color. The thickening agent has a shear factor, so that when the airspeed increases the fluids breaks down an runs off the wing. It is used during periods of freezing precip as a protective layer to prevent refreezing of the lifting surfaces. it is also very expensive, so the use of it is determned by whether the extra hold time is needed.
Hope this helps  Smile

We used type IV too, but I remember it being more of a green/blue not a bright green in color.

Here they still use type II, under the brand name Killfrost in a 75/25 mix with water. It also gels and has certain anti-icing properties.

We use Killfrost here too, it is type IV though, and we use it 100%. Killfrost ABC-S. I don't know if yours is a different version...?

Lufthansa seems to be using the green kind. It's cool to see how the fluid stays on the aircraft's skin pretty well, giving lufthansa that new cool livery people are talking about  eyebrow
