Title: Ethylene glycol in paint
Post by: cluelesswonderer on April 27, 2023, 10:42:20 PM

Peasantry question from member of non chemistry public. :D

Ethylene glycol in household paint or primer. What is its purpose, and does it pose a health hazard once the paint/primer is dry? Does it continue to offgas or contribute in any way to air pollution in the home? And if so, in what way? Does painting over top with a coat of paint that doesn’t contain EG change anything in terms of exposure post cure?

Thanks!

In that case it would evaporate and not be an issue once the paint is cured. Is that correct?

Yes, but this will go very slowly, because the vapour pressure is low.

Ok. I understand. Any information on how long ethylene glycol would take to evaporate out of paint?
