CHEM TRAILS!!!
;p

[godfish]

Well, in a way yes :))

So this is a plane pr0n? Coming on a plane? 😆
!LOL !BBH

[godfish]

Well, it's the plane I took yesterday night.

I guess you didn't get the joke. Sorry!

What is the composition of de-icing fluids?

[askrafiki]

Aircraft de-icing fluids come in four main types (I, II, III, IV), with Type I being the most common for initial de-icing.

Core composition:

• Propylene glycol (main antifreeze base, 50-100% concentration) or sometimes ethylene glycol (less common due to toxicity).
• Water (diluted to 25-100% fluid, depending on strength).
• Surfactants, dyes, and corrosion inhibitors (small percentages for better adhesion, visibility, and metal protection).
• Thickeners (in Types II-IV): Polymers like xanthan gum to increase viscosity for anti-icing holdover.

Types II-IV add these for longer protection but require higher shear-off speeds.

Take me with you.
