Contact us today for guidance in meeting your … Formulating with Exempt Solvents seldom used in the coatings industry because of their corrosiveness, poor solvency, toxicity, cost and odor. PCBTF is used in field applied architectural and industrial Maintenance (AIM) coatings; marine coatings; auto-refinish coatings; factory-applied metal, plastic, and wood coatings; and in adhesives and consumer products, including paint thinners. A: Tertiary butyl actetate (TBAc), also known as acetic acid, 1,1-dimethylethyl ester, was excluded from the definition of VOCs under the Regulations because it was determined that this compound has negligible reactivity and would not contribute in a meaningful way to the formation of ground-level ozone and particulate matter. EPA’s Safer Choice Program will allow the use of certain solvents that do not fully comply with the Safer Choice Criteria for Solvents (at. MIR is now being adopted as a replacement for Low Vapour Pressure as more flexible standard in determining suitability of a solvent as “VOC-exempt” or “low VOC”. T-Butyl Acetate (TBAC) TBAC is exempt in all states, except for the four California air districts mentioned above. Check the EDS or other technical data to see if the coating contains water and exempt solvents and if the VOC content is expressed as lbs VOC/gal., minus water and exempt solvents, or lbs/gal less exempt solvents. However, if this ends up being the case, the air district would need to realize additional VOC reductions elsewhere to avoid “backsliding.”. Exposure levels and discharges to drinking water sources that are below the NSRL or “safe harbor levels” are exempt from the requirements of Proposition 65. Contact ACA’s David Darling for more information. PC is a less aggressive solvent in certain I&I applications, but it is highly miscible and can be used in customized blends (i.e. Customers are needing to formulate VOC’s (Volatile Organic Compounds) out of their formula because of continual state and federal reductions in the amount of VOC’s that can be found in paint. "VOC regulatory" is the same as the term "VOC coating" used in many local air district rules, which is equivalent to the term "VOC, less water and exempts." Announce ATS Agreement, Solenis Licenses Corn Oil Extraction Technology to Hydrite. End Market Shipping Location. Hydrite has a wide portfolio of VOC exempt products including: 300 N. Patrick Blvd. 262-792-1450 This fall, OEHHA is expected to release a proposed PCBTF unit risk factor and No Significant Risk Level (NSRL). 8 Other VOC Exempt Solvents • In the United States today there are few VOC exempt solvents that are not HAPS (or ODS) and even fewer that can be purchased for less than $2.00/lb to allow formulators an option for low cost formulations for the coating, cleaning & adhesive markets. Hydrite Announces Headquarters Move To New Building, Hydrite Announces Nelson-Jameson as Exclusive Equipment Supplier, Hydrite Announces New Food Safety Program Manager, Hydrite Chemical Co Acquires Organic Defoamer Group, Hydrite Chemical Co. Acquires Servco Chemical, Hydrite Chemical Co. Additionally, solvents with certain positive environmental and performance characteristics (i.e. This offers the possible option for coating manufactures to maybe reformulate their product(s) to comply with the regulations. CARB is focussing on eliminating high-MIR VOCs which will have the greatest impact in lowering ambient VOC levels. Our VOC compliant and/or exempt solutions get the job done, legally and safely at a low(er) total cost of ownership. Although states are allowed to set more stringent limits on consumer products sold within their borders, California is the only state that has done so as of this date.VOC-content limits for consu… Over ACA’s contention that the NTP report excluded scientifically valid data which were not considered and that sufficiency of evidence criteria were not met, on June 28, 2019, OEHHA added PCBTF to the Proposition 65 list of chemicals. In 1999, when Environment Canada added VOCs to the list of toxic substances in CEPA Schedule 1, it listed 44 exempt com-pounds identical to the U.S. list of VOC-exempt compounds. For companies and their workers, using zero VOC cleaning solvents to replace solvents that contain hazardous VOCs is win-win situation. Cyclo-2245 VOC Exempt Solvent/ VOC Exempt Carrying Agent Decamethylcyclopentasiloxane (Cyclomethicone) Products Description: VOC Exempt Solvents/ Carrying agents are Cyclic Silicone fluids that are exempt from federal VOC regulations including California (CARB) regulations and OTC regulations. Brookfield, Wisconsin 53045 They are HAP-free and do not contribute to ozone-depletion and global warming. The vapor pressure of any solvent that does not fully comply with the solvent criteria must be low enough to qualify as “volatile organic compound (VOC)-exempt” (under California Air Resources … ACA has a PCBTF workgroup and is currently conducting an informal PCBTF survey to gather information in the development of additional reasoning that will hopefully minimize the impact of future PCBTF actions on the coatings and adhesives industry. Note that EPA will only exempt pure compounds. “Zero VOC” solvents are generally comprised of a blend of exempt solvents and may not be classified as VOC-exempt. In 2017, the National Toxicology Program (NTP) determined PCBTF to be a potential carcinogen. Rule 1113 (PDF) - Architectural Coatings contains the following limited exemption for tBAc: Submit Quote Request. Certain solvents are exempt for the rulings to. The South Coast AQMD’s certification of these products does not constitute or imply an endorsement by the South Coast AQMD nor does it certify their ability to meet the requirements for proper disposal of used water-based cleaners. Volume Needed. 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. Both nationally and within certain individual states, rules governing use of adhesives and sealants are aimed at maintaining air quality. For example, acetone is a VOC-exempt solvent. While typically a raw material supplier company would coordinate advocacy efforts to maintain PCBTF’s exempt VOC status, including filing comments, there are no domestic manufacturers of PCBTF — all production occurs in China. 262-792-8721 Fax. Also, compatibility concerns with acetone eliminate it from use in many carpet and furniture product formulas. VOC Exempt Solvents; VOC Exempt Solvents. There are only two nonhalogenated exempt solvents, acetone and methyl acetate. These clean air solvents comply with the VOC requirements of Rule 1122 - Solvent Degreasers and/or Rule 1171 – Solvent Cleaning Operations. Based on the NTP report, in 2018, SCAQMD asked the California Office of Environmental Health and Hazard Assessment (OEHHA) to evaluate the health data regarding the cancer potency of PCBTF. This list includes mostly halogenated compounds but also includes acetone and methyl acetate. Due to its classification as VOC exempt, dimethyl carbonate has grown in popularity and applications as a replacement for methyl ethyl ketone (MEK) and other solvents. These laws are in effect because certain volatile organic compounds (VOCs) found in some adhesive and sealant products react with nitrogen oxides in the air in the presence of sunlight to form the ozone and subsequently pose a health threat in the lower atmosphere by causing respiratory problems. The extensive use of PCBTF in industry products is largely because, in 1994, the U.S. Environmental Protection Agency (EPA) exempted PCBTF from its list of Volatile Organic Compounds (VOCs). “VOC-exempt” refers to a solvent that is on the VOC-exempt lists maintained by the EPA and SCAQMD. VOC-Exempt Solvents EPA regulations include a list of compounds that are explicitly exempted from regulation as VOCs, even though they are “compounds of carbon.” These include a short list of compounds such as carbon monoxide and carbon dioxide that historically have not been regulated as VOCs, and a longer list of compounds that EPA has classified as “negligibly reactive.” Exempt products including: 300 N.
