It has a flash point of −18 C (0 F). But the problem is that acetone evaporates very rapidly, so very slow solvents have to be added to make the thinner useful. Exempt products such as acetone and ammonia are very toxic but do not contribute to smog and are consequently used in low/zero VOC formulations of major manufacturers, safe from regulation and with no concern for users. Under the United States Environmental Protection Agency's (U.S. EPA) Clean Air Act, acetone is an exempt volatile organic compound (VOC). Transport sources. For example, acetone is a VOC-exempt solvent. In addition to these high boiling tails, acetone, tertiary butyl acetate, and parachlorobenzotrifluoride can be employed in various ratios depending on the binder and the coating type to complete the solvent system. 40 CFR 51.100(s) - Definition - Volatile organic compounds (VOC) (s) "Volatile organic compounds (VOC)" means any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, which participates in atmospheric photochemical reactions. 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. The global low VOC paint market was valued at USD 6,719.72 million in 2017, according to Mordor Intelligence, and an increase of 6.45% is expected by the year 2023. Bob Flexner is the author of "Understanding Wood Finishing." It is used to make nail polish remover and paint thinner. Acetone is by far the most common exempt VOC. Acetone is a common ingredient in domestic products. We can use as much acetone as we need for cleaning or to make our finishes work. Acetone occurs naturally in plants, trees, volcanic gases, forest fires and as a product of the breakdown of body fat. About 6.7 million tonnes were produced worldwide in 2010, mainly for use as a solvent and production of methyl methacrylate and bisphenol A. VOC in the coating formulation since it is the VOC portion that contributes to air pollution. However, this can be a challenge due to the presence of volatile organic compounds (VOCs). The VOC of Mixture is most easily understood if you picture a bucket of the mixed coating. Different VOCs have different health effects, and range from those It is used as a solvent in industry, lab, and home. Consumer products. Volatile Organic Compounds (VOC) Any chemical substance which contains compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, determined to have photochemical reactivity. Need help with VOC compliance? 434-1L-33018 MFG #: 434-1L. VOCs or HAPs per weight of solids. Currently PCBTF and TBAc are considered the two largest volume VOC exempt solvents being used but DMC (Dimethyl Carbonate) is quickly rising in usage. Its an exempt solvent from the VOC reporting. You could use regular mineral spirits and Penetrol, then it would flow out the best. These organic chemicals are substances made up of carbon and other elements, and they encompass nearly all carbon compounds with the exception of carbon dioxide and carbon monoxide. the VOC emissions from all the coatings and solvents used to calculate total VOC emissions in pounds per month. Companies are guaranteed to save money by avoiding chemicals that are hazardous and require costly disposal. If handled improperly, acetone may pose a dangerous fire risk. $12.95 / CN Available to Order - 0 on Hand Brand Name: MG Chemicals This item is hazardous and may be subject to an additional handling fee which will appear on your invoice. Maintaining good indoor air quality (IAQ) is critical for health and safety. “VOC-exempt” refers to a solvent that is on the VOC-exempt lists maintained by the EPA and SCAQMD. As indicated above, the reduction of VOC content is certainly beneficial to the overall environment. VOCs are a group of carbon-based chemicals that easily evaporate at room temperature. In California and other areas with strict VOC laws, manufacturers make their thinners using a high percentage of acetone because acetone is an exempt solvent manufacturers can use all they want. Why Choose Preptone? The common few include Acetone, Methylacetate, Tertiary Butyl Acetate (TBAC), and Parachlorobenzotriflouride, (PCBTF). When released into the soil, this material is expected to leach into groundwater. VOC is the acronym for volatile organic compound – that is, an environmental (smog) pollutant. They only say to use acetone to thin as acetone is VOC exempt, not because it's the best. Overall Weight of VOC – Each component in the bucket has a specific weight of VOC in it. Fast Drying Voc-Exempt Acetone, 32 fl.oz Can ; Fast Drying Voc-Exempt Acetone, 32 fl.oz Can. This includes You may have noticed that acetone is becoming more widely available. Acetone, methylene chloride, methyl acetate and parachlorobenzotrifluoride (PCBTF), which was originally marketed under the trade name Oxsol 100, are all examples of exempt VOCs.Thus, you can buy zero VOC lacquer that is 75 percent volatile organic compound solvent, yet is legally free of VOCs. Many of solvent borne coatings suggest compliance but in reality contain exempt VOCs and HAPs. We use a lot of Prime Coatings solvent based paints, and use nothing but acetone to thin. Acetone is a compound, and it is organic, colorless, volatile, flammable, and has a unique odor. Ecological Information Environmental Fate: When released into the soil, this material is expected to readily biod egrade. “Zero VOC” solvents are generally comprised of a blend of exempt solvents and may not be classified as VOC-exempt. Just because a product has VOC exemption does not mean it is safe to use in all applications. Acetone (67- 64 -1) No No None 12. Acetone is miscible with water and serves as an important organic solvent in its own right, in industry, home, and laboratory. When rel eased into the soil, this material is expected to quickly evaporate. * Extract from 40 CFR 59.203(f): Under EPA regulations, a chemical is VOC-exempt, if it: - Has vapor pressure of less than 0.1 millimeters of mercury (at 20 degrees Celsius); Or, if the vapor pressure is unknown: - Consists of more than 12 carbon atoms; or In any given exempt formulation, these high boiling solvents make up most, if not all, of the non-exempt solvents. The VOC of material is the same as the term "actual VOC," which is equivalent to the term "VOC, including water and exempts." Only single component solvents that have been found not to contribute to ground level smog may be classified as VOC-exempt. So, if you aren’t yet manufacturing or selling low-VOC products, now is a great time to start. Product Comparison - Examine Ingredients •Product A •Product B Ingredient CAS # Wt %MIR Value Overall MIR Lists Acetone 67-64-1 52% 0.36 0.83 VOC Exempt Heptane-branched, cyclic and linear 426260-76-6 40% 1.47 Heptane 142-82-5 5% 1.07 The use of VOC-containing products will inadvertently release VOCs which cause air pollution and smog. But what makes acetone really stand out as we become more environmentally conscious is its exemption as a VOC and HAP. Because of its low flash point and … Formulating coatings either free of VOCs or with exempt materials present many challenges. Why VOC’s matter? 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. So definitely run your tests.

Why some solvents are given VOC exempt status by the EPA and what the future holds Some of the solvents in your finishes might be “exempt,” meaning they don’t count as VOCs even though they are volatile, organic and compounds. Many common household materials and products, such as paints and cleaning products, give off VOCs. VOCs (volatile organic compounds) are found in wide variety of everyday products such as solvent-based paints/coatings, adhesives, sealants, printing inks, many consumer products, organic solvents and petroleum products. Why not just use an EPA VOC-exempt solvent? Your body also produces acetone when it breaks down fat. The acetone present in Preptone is VOC exempt, this quality enables its vapors and VOC content to remain below regulatory limits. If this total is less than 1,666 pounds per month, the facility is exempt from needing a … • Effective 9/30/09, TBAC is VOC-exempt in Canada for architectural and automotive coatings • US and Canadian Regulations based on photochemical reactivity – Only photochemically reactive compounds are regulated – Negligibly reactive compounds are exempt: • Acetone, methyl acetate, TBAC, many halogenated solvents. It is on the VOC exempt list as it has no restrictions even though volatile. VOC-containing products. Acetone is a petroleum-derived product. Although acetone is an excellent solvent and is relatively non-toxic, it is extremely flammable. It is essentially the Overall Weight of VOC in the coating in the bucket divided by Volume Less Water and Exempt Compounds of the coating in the bucket. Acetone is produced and disposed of in the human body through normal metabolic processes. The problem Rustoleum and the modern oils have is they tend to not level too well, due to the lower VOC content. the VOC content of Safer Choice products. Exempt VOC - 1 Revised 1/2/08 EXEMPT VOC LIST VOC (Volatile Organic Compounds) - For all areas in Missouri VOC means any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, that participates in atmospheric photochemical reactions to produce ozone. As of 3/31/2009 . Acetone is present in the vehicle exhaust of cars, aeroplanes and from railway operations. Familiar household uses of acetone are as the active ingredient in nail polish remover and as paint thinner. It … As mentioned in the Introduction, the older regulations were concerned with VOCs, while the newer ones have been written with the focus on HAPs.The calculation methods are very similar. Total US volume of VOC Exempt solvents market not including Acetone is estimated to be 30,000 MT per year. Common VOCs include acetone, benzene, ethylene glycol, formaldehyde, methylene chloride, perchloroethylene, toluene and xylene. I can't speak for other manufacturers paints, but I would try that anywhere I could, simply so it can stay off the reports. Again, only the HAPs appear in the numerator, but all of the liquids appear in the denominator.. VOC Calculator 3. Kingsport, Tenn. (January 24, 2005) - To help meet customer demand for alternatives to acetone, Eastman Chemical Company offers Eastman Methyl Acetate, a non-HAP, VOC-exempt replacement. VOC is usually defined to indicate only the compounds, or solvents, that participate in photochemical (smog-forming) reactions.
