VOC  are the solvents that escape during painting.  Unfortunate the numbers vary on all painting cans and paint products so it is difficult to so if they are low VOC  or not.

Diamond Vogel has a product that is call Zero Plus that has Zero  VOC!!

Sherwin Williams has a zero VOC paint  call ProMar 200 Zero VOC


After looking at the material data sheet you will find that there are still solvents in the paint no matter what the rating

The best recommendation is that proper ventilation no matter what paint you are using.
