Question:

What are the effects of an O2 rich environment on powder coating? Is there any possibility of combustion when powder coating comes into contact with liquid oxygen? S. L.

Answer:

Powder coatings, once cured, are pretty much inert and non-reactive compounds. They will not catch fire in liquid oxygen without a source of ignition. However, they will be very brittle, considering that liquid oxygen is about –200°C (-430°F) and would likely shatter under the slightest mechanical force.
