  • The Permitting and Regulatory Nightmares of Using EPA Method 24 to Determine the VOC Content of Water-Based Coatings and Adhesives

    Many industries throughout the United States use water-based adhesives in their manufacturing processes. These adhesives typically have a very low volatile organic compound (VOC) content of less than 50 grams per liter (g/L). At present, the United States Environmental Protection Agency (EPA) and a California Air Quality Management District (CAQMD) mandate the use of EPA Method 24 to determine ...
