These products are very effective at blocking VOCs, including formaldehyde, from old paints and building materials.

What is considered low VOC sealer?

How does VOC affect the environment?

VOCs play a significant role in the formation of ozone and fine particulates in the atmosphere. Under sunlight, VOCs react with nitrogen oxides emitted mainly from vehicles, power plants and industrial activities to form ozone, which in turn helps the formation of fine particulates.

Is alcohol a VOC?

VOC is most often stated as a percentage, so the percentage of the full mixture that is not VOC exempt. For example, isopropyl alcohol (IPA) is not exempt by EPA (and most if not all other) standards, so 99% pure IPA has a VOC of 99%. 70% pure IPA, with 30% purified water, is 70% VOC, because water is exempt.
