The term VOC stands for volatile organic compounds. These are a group of organic chemicals that have a high vapor pressure at room temperature, which means they can easily become gases or vapors. VOCs are prevalent in many products, including paints, solvents, adhesives, and cleaning agents.

Understanding VOCs is crucial, particularly in surface coating applications, as they can contribute to air pollution and may have health implications for individuals exposed to them. Regulations often aim to limit the amount of VOCs in products to promote better air quality and overall health, making it significant for professionals in surface coatings to be aware of these compounds and their effects.

The other choices, while related to different contexts, do not define VOC. Variable operating capacity refers to a different concept primarily found in system performance discussions, volume of coating pertains to the measurement of coating materials used, and visible optical clarity relates to the transparency of a material. Each of these concepts is relevant in specific fields but does not relate to the term VOC.
