The Ins and Outs of Low VOC Paint
What Is Low VOC Paint?
Volatile organic compounds (VOC’s) are gases that are emitted by various solids and liquids. With many having short- and long-term adverse health effects. Traditional paint solvents often contain high quantities of VOCs. Conversely, low VOC paints have relatively low levels of VOC’s. Low VOC paint has been shown to improve indoor air quality and reduce urban smog. A few of the benefits of using low VOC paint include low odor, clean air, and safer technology. In addition, low VOC paint is extremely durable and has a washable finish.
History of Low VOC Paint
1900s: Mass production of paint begins. Binders, additives, and solvents are added to paint, increasing the amount of VOCs in commercial paint.
1960: Paint manufactures incorporate as much lead and VOC’s as they see fit.
1966: Los Angeles, California institutes Rule 66. The first law attempting to limit the amount of VOCs in paint.
1967: The Federal Government enforces the new Clean Air Act (CCA). The first Federal law attempting to limit the amount of VOCs in paint.
1990: The Clean Air Act is updated and adds 189 toxins that must be removed from the environment.
1992: Glidden Company produces the first VOC-free coating. High prices limit its adoption.
2005: The Green Chemistry Research & Development Act is enacted. The passage of this law increases the awareness of green chemistry and its attempt to decrease air pollution.
Side Effects of VOCs
The ability of organic chemicals to cause health effects will vary greatly. As with other pollutants, the extent and nature of the health effect will depend on many factors including the level of exposure and length of time exposed.
Key signs and symptoms that are associated with exposure to VOCs:
nose and throat discomfort
allergic skin reaction
declines in serum cholinesterase levels
Immediate symptoms that are associated with longer exposure to VOCs include:
Eye and respiratory tract irritation
visual disorders and memory impairment
Some of the long-term health effects of VOC exposure include:
Eye, nose and throat irritation
Headaches, loss of coordination and nausea
Damage to the liver, kidney and central nervous system
Some organics can cause cancer in animals, some are suspected or known to cause cancer in humans.
How Low VOC Paint Is Different Than Normal Paint
Low VOC Paint:
Low VOC paints have reduced amounts of volatile organic compounds. This means that they do not release as much gas (VOCs) when compared to traditional paints. One important fact to remember is that low VOC does not mean NO VOC. Low VOC only means it has a lower amount of VOCs compared to that of traditional paint. Currently, there is no set standard that defines what "low" means. Therefore, be careful when reading labels when buying paint.

No VOC Paint:
Paints with no VOCs have absolutely no volatile organic compounds in them. But keep in mind, just because it is missing VOCs doesn't mean its chemical free. In fact, the paint tinting process can sometimes add some VOCs. That said, these are still a great option.
