Given the extensive use of PCTBF in the coatings industry, these changes could be very problematic. Introduction For decades, regulatory agencies in most industrialized nations have enacted more and more stringent volatile organic compounds (VOC) regulations to reduce the solvent content in coatings. The VOC content values are the result of calculations using the weight solids and density determinations. The same is true of the new Universal Flux Remover (#MCC-UFR) which is 100% VOC exempt. For most coatings, VOC content is calculated by subtracting the pounds of exempt solvent from the numerator and the gallons of exempt solvent from the denominator. SCAQMD is expected to delete the exemptions for TBAC for Industrial Maintenance and certain Auto Refinish Coatings later in 2018. Unless you recycle exempt solvents, such as ac-etone, the VOC content of the recycled solvent may be … Evidence shows that HFO 1336mzz-Z is negligibly reactive in forming ground-level ozone. VOC exempt status does not mean that the solvent is non-flammable and thus safety must be carefully considered. For the purpose of this rule, tertiary butyl acetate (tBAc) shall be considered exempt as a VOC only for purposes of VOC emissions limitations or VOC content requirements and will continue to be a VOC for purposes of all recordkeeping, emissions reporting, photochemical dispersion modeling, and inventory requirements which apply to VOCs, when used in industrial maintenance coatings, including zinc-rich … Propylene Carbonate (also specifically exempted by EPA): Propylene Carbonate is exempted as a low reactivity compound by the EPA and also qualifies for the LVP-VOC exemption.

There is nothing you can do to claim an exemption for it. VOC exempt solvents are organic compounds that are exempt from restrictions placed on most volatile organic compounds (VOCs) in the United States[1][2]. T-Butyl Acetate (TBAC) VOC-Exempt Solvents. California’s South Coast Air Quality Management District (SCAQMD), Bay Area AQMD, San Diego AQMD, and Sacramento AQMD have not exempted several of these compounds, and recent regulatory activities in these air districts will likely lead to the removal of several exemptions and further restrictions. While EPA has exempted these compounds, various states and California Air Districts have to go through a rulemaking to adopt these exemptions (many have a direct reference to the EPA exemption, so the compounds are automatically exempted in many State when EPA exempts). Reducing the VOC content of industrial cleaning solvent allowed to be used in subject cleaning activities from 900 g/l to 50 g/l would be a reduction of approximately 95% or 95% control efficiency ([(900 g/l—50 g/l) / … S.A.F.E.
