VOC: Volatile organic compounds. VOC's are toxins commonly found in conventional paints, sealers, and finishes. VOC's off-gas into the air and are not good to people or to the environment.
VOCs or "volatile organic compounds" VOCs are primarily the lighter 'fractions' of oil or hydrocarbons (i.e., the parts that evaporate easily because they have a low boiling point).
Aerobic Treatment Process by which microbes decompose complex organic compounds in the presence of oxygen and use the liberated energy for reproduction and growth. Aerosol Suspended droplets of liquid or fine solid particles in air.
Most people use the terms "hydrocarbon" and "volatile organic compounds" (or VOCs) to mean the same thing.
Low VOC Materials - VOC’s, or Volatile Organic Compounds, are chemicals which evaporate into the air during the curing or, in some cases, throughout the life of the material.
