By now you’ve probably heard of the term “VOC” when talking
about paints and finishes. Like many you’re probably wondering what this
exactly means. VOC stands for Volatile Organic Compound, meaning organic
chemicals that have a high vapour pressure at room-temperature. Their high
vapour pressure is because of a low boiling point, thus causing large molecules
to evaporate or sublimate from the liquid or solid form.
For example, formaldehyde has a boiling point of -19 degrees
Celsius. Slowly, over an extended amount of time the chemical would slowly exit
the paint and diffuse into the air we breathe.
VOC’s are regulated by law and have a low concentration.
Although VOC’s are considered to be acutely toxic to humans, long term exposure
to these chemicals can cause a slow development of several different health
complications. Several health effects being; eye, nose and throat irritation;
headaches, loss of coordination, nausea; damage to liver, kidney and central
nervous system. Some organic compounds can cause cancer in both humans and
animals. The health effects are all in determinate to the length of time
exposed and level of toxicity within the paints.
Canada considers VOC’s to have a boiling point of 50-250
degrees Celsius. “The term “organic compound” covers all chemicals that contain
carbon and hydrogen” according to the government’s webpage.
Check out this table taken from the government’s website as well. Do you
recognize any of them?

As you can see a source for many VOCs is paint. That’s why
we pride ourselves on offering extremely low, or no VOC paints. Our customer’s
health is our number one concern.
