25 Pa. Code § 130.603
(a) VOC content limits. Except as provided in subsections (b), (c) and (g), a person after January 1, 2005, may not:
(b) Most restrictive VOC limit. If on the container of an architectural or industrial maintenance coating, or a label or sticker affixed to the container, or in sales, advertising or technical literature supplied by a manufacturer or a person acting on their behalf, a representation is made that indicates that the coating meets the definition of or is recommended for use for more than one of the coating categories listed in Table 1, then the most restrictive VOC content limit applies. This provision does not apply to the following coating categories:
(g) Lacquers. Notwithstanding the provisions of subsection (a), a person or facility may add up to 10% by volume of VOC to a lacquer to avoid blushing of the finish during days with relative humidity greater than 70% and temperature below 65°F, at the time of application, provided that the coating contains acetone and no more than 550 grams of VOC per liter of coating, less water and exempt compounds, prior to the addition of VOC.
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.
