Good question,
Unfortunately there is not an easy answer.
It depends on
what the Volatiles are that are in your particular product.
The solvents should evaporate and will lesson as the product cures. It is off gassing that you smell from fresh paint or new carpet.
Other things can continue to off gas over time so it can effect the air quality of your breathing space. It also depends on how air tight your trailer is and how much fresh air you are introducing. (air exchanging)
There are low and non VOC products, but they can be misleading and contain VOC's, just not the regulated and recognized ones, but I think that they could be a preferable alternative. It really depends on what it is and how concerned you are about it.
Also, VOC are a complicated and many varied lot, it includes methane gas, which you may also off gas, I'm just not sure of your level of acceptability in your confined air space.
You even breath out VOC's they are everywhere and in just about everything.
Formaldehyde is one that you might want to avoid.
So I suggest you do a little research of your own and take in-account your sensitivity and your personal risk assessment and make a decision before using it in a small confined space.
