How do VOC and non-VOC adhesives compare?
~ Article courtesy of Master Bond Volatile organic compounds (VOCs) are compounds that have high vapor pressure and low water solubility. Many VOCs are human-made chemicals used and produced in the manufacturing of paints, pharmaceuticals, and refrigerants. VOCs are typically industrial solvents or by-products produced by chlorination in water treatment, such as chloroform. They’re…
