Industrial applications of adhesives and sealants are subject to air quality regulations in the states and local air districts in California. There is no national rule for industrial adhesives and sealants. Rule 1168 remains the most stringent regulation for industrial adhesive applications, and it has been embraced by the Green Building community as the "standard" for adhesives and sealants in the construction of new buildings.
Earlier this month, California’s South Coast Air Quality Management District (SCAQMD) began its regulatory process for amending Rule 1168 governing Industrial Adhesive and Sealants.
The test methods — ASTM D6886 and SCAQMD Method 313 — are intended to be used to analyze the VOC content of coatings less than 150 g/L. While coatings manufacturers can use formulation data to determine the VOC content of a product, SCAQMD will likely use Method 313 for enforcement purposes.
