How do volatile organic compounds from solvent-based adhesives affect the environment?

Volatile organic compounds (VOCs) from solvent-based adhesives pose significant risks to the environment by contributing to air pollution. When these adhesives are applied and cured, they release low-molecular-weight organic solvents into the atmosphere.12

In the lower atmosphere, these VOCs undergo photochemical reactions in the presence of sunlight, particularly when interacting with nitrogen oxides. This process generates ozone, a highly toxic gas that is a primary component of photochemical smog. This smog is environmentally harmful, as it causes damage to plants, reduces visibility, and creates atmospheric conditions that are hazardous to human health, including respiratory distress and eye irritation.34

Due to these detrimental effects, there is a strong ethical and regulatory imperative to reduce VOC emissions. Consequently, the industry is actively shifting away from solvent-based systems toward water-based adhesives to mitigate these environmental impacts and comply with increasingly strict pollution-control regulations.12
