It … But the problem is that acetone evaporates very rapidly, so very slow solvents have to be added to make the thinner useful. VOC is the acronym for volatile organic compound – that is, an environmental (smog) pollutant. Acetone is by far the most common exempt VOC. It is used to make nail polish remover and paint thinner. But what makes acetone really stand out as we become more environmentally conscious is its exemption as a VOC and HAP. Familiar household uses of acetone are as the active ingredient in nail polish remover and as paint thinner. Need help with VOC compliance? Why some solvents are given VOC exempt status by the EPA and what the future holds VOCs or HAPs per weight of solids. The acetone present in Preptone is VOC exempt, this quality enables its vapors and VOC content to remain below regulatory limits. 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. It is on the VOC exempt list as it has no restrictions even though volatile. Why not just use an EPA VOC-exempt solvent? Why Choose Preptone? If handled improperly, acetone may pose a dangerous fire risk. 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. 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 VOCs are a group of carbon-based chemicals that easily evaporate at room temperature.

Only single component solvents that have been found not to contribute to ground level smog may be classified as VOC-exempt. In any given exempt formulation, these high boiling solvents make up most, if not all, of the non-exempt solvents. 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. Many of solvent borne coatings suggest compliance but in reality contain exempt VOCs and HAPs. Currently PCBTF and TBAc are considered the two largest volume VOC exempt solvents being used but DMC (Dimethyl Carbonate) is quickly rising in usage. This is primarily because it’s the only commonly available solvent that is classified as an exempt VOC solvent. Bob Flexner is the author of "Understanding Wood Finishing." As of 3/31/2009 . Under the United States Environmental Protection Agency's (U.S. EPA) Clean Air Act, acetone is an exempt volatile organic compound (VOC). Total US volume of VOC Exempt solvents market not including Acetone is estimated to be 30,000 MT per year. It has a flash point of −18 C (0 F). This includes I can't speak for other manufacturers paints, but I would try that anywhere I could, simply so it can stay off the reports. VOC is usually defined to indicate only the compounds, or solvents, that participate in photochemical (smog-forming) reactions. $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. So definitely run your tests. You could use regular mineral spirits and Penetrol, then it would flow out the best. When released into the soil, this material is expected to leach into groundwater. the VOC content of Safer Choice products. 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. “VOC-exempt” refers to a solvent that is on the VOC-exempt lists maintained by the EPA and SCAQMD. 434-1L-33018 MFG #: 434-1L. Just because a product has VOC exemption does not mean it is safe to use in all applications. You may have noticed that acetone is becoming more widely available. 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. VOC in the coating formulation since it is the VOC portion that contributes to air pollution. 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. As indicated above, the reduction of VOC content is certainly beneficial to the overall environment. Maintaining good indoor air quality (IAQ) is critical for health and safety. For example, acetone is a VOC-exempt solvent. 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. About 6.7 million tonnes were produced worldwide in 2010, mainly for use as a solvent and production of methyl methacrylate and bisphenol A. The VOC of material is the same as the term "actual VOC," which is equivalent to the term "VOC, including water and exempts." 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. Companies are guaranteed to save money by avoiding chemicals that are hazardous and require costly disposal. “Zero VOC” solvents are generally comprised of a blend of exempt solvents and may not be classified as VOC-exempt. However, this can be a challenge due to the presence of volatile organic compounds (VOCs). Acetone is produced and disposed of in the human body through normal metabolic processes. Acetone (67- 64 -1) No No None 12. If this total is less than 1,666 pounds per month, the facility is exempt from needing a … * 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 Different VOCs have different health effects, and range from those 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-containing products. The use of VOC-containing products will inadvertently release VOCs which cause air pollution and smog. Why VOC’s matter? Consumer products. Its an exempt solvent from the VOC reporting. Acetone is a petroleum-derived product. The problem Rustoleum and the modern oils have is they tend to not level too well, due to the lower VOC content. Acetone is a common ingredient in domestic 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. • 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. So, if you aren’t yet manufacturing or selling low-VOC products, now is a great time to start. 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. 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. It has volatile organic compound (VOC) exempt status in the USA. They only say to use acetone to thin as acetone is VOC exempt, not because it's the best. Acetone is present in the vehicle exhaust of cars, aeroplanes and from railway operations. Overall Weight of VOC – Each component in the bucket has a specific weight of VOC in it. Because of its low flash point and … Again, only the HAPs appear in the numerator, but all of the liquids appear in the denominator.. VOC Calculator 3. Acetone is a compound, and it is organic, colorless, volatile, flammable, and has a unique odor. Many common household materials and products, such as paints and cleaning products, give off VOCs. Common VOCs include acetone, benzene, ethylene glycol, formaldehyde, methylene chloride, perchloroethylene, toluene and xylene. Ecological Information Environmental Fate: When released into the soil, this material is expected to readily biod egrade. The VOC of Mixture is most easily understood if you picture a bucket of the mixed coating. The common few include Acetone, Methylacetate, Tertiary Butyl Acetate (TBAC), and Parachlorobenzotriflouride, (PCBTF). When rel eased into the soil, this material is expected to quickly evaporate. 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. the VOC emissions from all the coatings and solvents used to calculate total VOC emissions in pounds per month. 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. We use a lot of Prime Coatings solvent based paints, and use nothing but acetone to thin. Acetone is miscible with water and serves as an important organic solvent in its own right, in industry, home, and laboratory. Acetone occurs naturally in plants, trees, volcanic gases, forest fires and as a product of the breakdown of body fat. 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.
