VOC Content Limits for Architectural and Industrial Maintenance Coatings

The VOC content limits are effective on January 1, 2005, and are expressed in grams of VOC per liter¹ of coating thinned to the manufacturer’s maximum recommendation, excluding the volume of any water, exempt compounds, or colorant added to tint bases. ‘‘Manufacturer’s maximum recommendation’’ means the maximum recommendation for thinning that is indicated on the label or lid of the coating container.
