Rule 1113 (PDF) - Architectural Coatings contains the following limited exemption for tBAc: "VOLATILE ORGANIC COMPOUND (VOC) is as defined in Rule 102 Definition of Terms. These include Coatings, Adhesives, Sealants and Elastomers . Safety [ edit] VOC exempt status does not mean that the solvent is non-flammable and thus safety must be carefully considered. VOC exempt solvents are organic compounds that are exempt from restrictions placed on most volatile organic compounds (VOCs) in the United States. f |A 28(R]:8W5f--.jFR+F{3fAL2qwSFdF Eastman solvents portfolio includes: non-HAP solvents, many with low MIR (Maximum Incremental Reactivity) values, LVP-VOC solvents and even a non-HAP, VOC-exempt solvent (Eastman Methyl Acetate). endobj Oct 2018 - Present 4 years 5 months. The potential for a VOC to react with NOx to form smog, i.e., the maximum incremental reactivity (MIR) of a VOC, varies from compound to compound. Organic materials that do not appear on this appendix and are not classified as a VOC or an exempt VOC can be summed into the category "Grouped LVP" in the 2018 ART. Volatile Organic Compounds (VOC) react with nitrogen oxides on hot summer days to form ozone (smog). As a result, air quality regulations focus on VOCs that increase ground-level ozone concentrations, and exclude compounds with negligible reactivity. Some rules include prohibitions from using certain Group II Exempt Compounds as they have potential toxic health risks, as well as being contributors to upper-atmosphere ozone depletion and other potential environmental impacts. 262-792-1450 As per section 5.5 of the Standard, solvents that can VOC 0.0 lbs/gal mixed T-547 DYNA-ZV Urethane Catalyst. The United States Environmental Protection Agency (U.S. EPA) excludes certain organic compounds from the regulatory definition of a VOC based on the compound's negligible contribution to the formation of ground-level ozone, better known as smog. tert-Butyl acetate is used as a solvent in the production of lacquers, enamels, inks, adhesives, thinners and industrial cleaners.

Short-term exposure can cause symptoms such as upset stomach, difficulty breathing, and watery eyes. 2023 Obtaining a VOC exemption means that CARB will add the compound to the list of exempt compounds in the VOC definition for the applicable regulation. VOCs that are determined to have negligible photochemical reactivity may be exempt from being included in VOC content calculations because these chemicals do not lead to the formation of ground-level ozone. Compounds with reactivity levels lower than, or equal to, ethane under the assumed conditions, may be deemed negligibly reactive. 262-792-8721 Fax. endobj VOC Exempt Silicone Lubricants can be applied to a wide range of surfaces including plastic, rubber & vinyl.
