Many common household materials and products, such as paints and cleaning products, give off VOCs. It has volatile organic compound (VOC) exempt status in the USA. 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. Again, only the HAPs appear in the numerator, but all of the liquids appear in the denominator.. VOC Calculator 3. 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. In any given exempt formulation, these high boiling solvents make up most, if not all, of the non-exempt solvents. So definitely run your tests. It is used as a solvent in industry, lab, and home. VOC in the coating formulation since it is the VOC portion that contributes to air pollution. When rel eased into the soil, this material is expected to quickly evaporate. For example, acetone is a VOC-exempt solvent. It … 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 Many of solvent borne coatings suggest compliance but in reality contain exempt VOCs and HAPs. The common few include Acetone, Methylacetate, Tertiary Butyl Acetate (TBAC), and Parachlorobenzotriflouride, (PCBTF). Why Choose Preptone? Bob Flexner is the author of "Understanding Wood Finishing." The VOC of material is the same as the term "actual VOC," which is equivalent to the term "VOC, including water and exempts." Overall Weight of VOC – Each component in the bucket has a specific weight of VOC in it. As of 3/31/2009 . Need help with VOC compliance? Acetone is a compound, and it is organic, colorless, volatile, flammable, and has a unique odor. About 6.7 million tonnes were produced worldwide in 2010, mainly for use as a solvent and production of methyl methacrylate and bisphenol A. 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. Acetone is present in the vehicle exhaust of cars, aeroplanes and from railway operations. Acetone is produced and disposed of in the human body through normal metabolic processes. 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. But what makes acetone really stand out as we become more environmentally conscious is its exemption as a VOC and HAP. 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. 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. This includes Why some solvents are given VOC exempt status by the EPA and what the future holds Only single component solvents that have been found not to contribute to ground level smog may be classified as VOC-exempt. $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. Just because a product has VOC exemption does not mean it is safe to use in all applications. VOCs are a group of carbon-based chemicals that easily evaporate at room temperature. Acetone is a common ingredient in domestic products. VOC is the acronym for volatile organic compound – that is, an environmental (smog) pollutant. Acetone is by far the most common exempt VOC. Acetone occurs naturally in plants, trees, volcanic gases, forest fires and as a product of the breakdown of body fat. We use a lot of Prime Coatings solvent based paints, and use nothing but acetone to thin. 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. Companies are guaranteed to save money by avoiding chemicals that are hazardous and require costly disposal. Why not just use an EPA VOC-exempt solvent? Currently PCBTF and TBAc are considered the two largest volume VOC exempt solvents being used but DMC (Dimethyl Carbonate) is quickly rising in usage. Maintaining good indoor air quality (IAQ) is critical for health and safety. This is primarily because it’s the only commonly available solvent that is classified as an exempt VOC solvent. However, this can be a challenge due to the presence of volatile organic compounds (VOCs). Acetone is a petroleum-derived product. I can't speak for other manufacturers paints, but I would try that anywhere I could, simply so it can stay off the reports. If handled improperly, acetone may pose a dangerous fire risk. * 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 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. Total US volume of VOC Exempt solvents market not including Acetone is estimated to be 30,000 MT per year. Acetone is miscible with water and serves as an important organic solvent in its own right, in industry, home, and laboratory. It is used to make nail polish remover and paint thinner. It has a flash point of −18 C (0 F). 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. Fast Drying Voc-Exempt Acetone, 32 fl.oz Can ; Fast Drying Voc-Exempt Acetone, 32 fl.oz Can. The acetone present in Preptone is VOC exempt, this quality enables its vapors and VOC content to remain below regulatory limits. 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. the VOC emissions from all the coatings and solvents used to calculate total VOC emissions in pounds per month. “VOC-exempt” refers to a solvent that is on the VOC-exempt lists maintained by the EPA and SCAQMD. Although acetone is an excellent solvent and is relatively non-toxic, it is extremely flammable. 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. Familiar household uses of acetone are as the active ingredient in nail polish remover and as paint thinner. Formulating coatings either free of VOCs or with exempt materials present many challenges. Acetone (67- 64 -1) No No None 12. The VOC of Mixture is most easily understood if you picture a bucket of the mixed coating. “Zero VOC” solvents are generally comprised of a blend of exempt solvents and may not be classified as VOC-exempt. Your body also produces acetone when it breaks down fat. Ecological Information Environmental Fate: When released into the soil, this material is expected to readily biod egrade. Different VOCs have different health effects, and range from those 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. VOC is usually defined to indicate only the compounds, or solvents, that participate in photochemical (smog-forming) reactions. You could use regular mineral spirits and Penetrol, then it would flow out the best. 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. Consumer products. If this total is less than 1,666 pounds per month, the facility is exempt from needing a … the VOC content of Safer Choice products. We can use as much acetone as we need for cleaning or to make our finishes work. 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 use of VOC-containing products will inadvertently release VOCs which cause air pollution and smog. The problem Rustoleum and the modern oils have is they tend to not level too well, due to the lower VOC content.

Transport sources. VOC-containing products. 434-1L-33018 MFG #: 434-1L. When released into the soil, this material is expected to leach into groundwater. Because of its low flash point and … • 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. 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. Why VOC’s matter? VOCs or HAPs per weight of solids. 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. You may have noticed that acetone is becoming more widely available. But the problem is that acetone evaporates very rapidly, so very slow solvents have to be added to make the thinner useful.
