Just because a product has VOC exemption does not mean it is safe to use in all applications. The VOC of Mixture is most easily understood if you picture a bucket of the mixed coating. The use of VOC-containing products will inadvertently release VOCs which cause air pollution and smog. 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. This is primarily because it’s the only commonly available solvent that is classified as an exempt VOC solvent. It … It has volatile organic compound (VOC) exempt status in the USA. Formulating coatings either free of VOCs or with exempt materials present many challenges. Its an exempt solvent from the VOC reporting. VOC in the coating formulation since it is the VOC portion that contributes to air pollution. For example, acetone is a VOC-exempt solvent. Why VOC’s matter? If handled improperly, acetone may pose a dangerous fire risk. 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. Ecological Information Environmental Fate: When released into the soil, this material is expected to readily biod egrade. It is used as a solvent in industry, lab, and home. 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. So, if you aren’t yet manufacturing or selling low-VOC products, now is a great time to start. They only say to use acetone to thin as acetone is VOC exempt, not because it's the best. When released into the soil, this material is expected to leach into groundwater. VOC-containing products. Acetone occurs naturally in plants, trees, volcanic gases, forest fires and as a product of the breakdown of body fat. Acetone is a compound, and it is organic, colorless, volatile, flammable, and has a unique odor. We can use as much acetone as we need for cleaning or to make our finishes work. Why some solvents are given VOC exempt status by the EPA and what the future holds 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. VOC is usually defined to indicate only the compounds, or solvents, that participate in photochemical (smog-forming) reactions. This includes Only single component solvents that have been found not to contribute to ground level smog may be classified as VOC-exempt. You could use regular mineral spirits and Penetrol, then it would flow out the best. the VOC emissions from all the coatings and solvents used to calculate total VOC emissions in pounds per month. 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. Call 800 563-1305 or email for a response within 48 hours ‘guaranteed.’ We handle all inquiries confidentially and will develop a custom blend if one of our many off-the-shelf low VOC or VOC exempt solutions do not meet all your success criteria. “Zero VOC” solvents are generally comprised of a blend of exempt solvents and may not be classified as VOC-exempt. 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. Currently PCBTF and TBAc are considered the two largest volume VOC exempt solvents being used but DMC (Dimethyl Carbonate) is quickly rising in usage. Bob Flexner is the author of "Understanding Wood Finishing." 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. 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 (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. Total US volume of VOC Exempt solvents market not including Acetone is estimated to be 30,000 MT per year. Many common household materials and products, such as paints and cleaning products, give off VOCs. • 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. Maintaining good indoor air quality (IAQ) is critical for health and safety. The acetone present in Preptone is VOC exempt, this quality enables its vapors and VOC content to remain below regulatory limits. * 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 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. I can't speak for other manufacturers paints, but I would try that anywhere I could, simply so it can stay off the reports. 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. However, this can be a challenge due to the presence of volatile organic compounds (VOCs). 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. The common few include Acetone, Methylacetate, Tertiary Butyl Acetate (TBAC), and Parachlorobenzotriflouride, (PCBTF). Fast Drying Voc-Exempt Acetone, 32 fl.oz Can ; Fast Drying Voc-Exempt Acetone, 32 fl.oz Can. Acetone is a common ingredient in domestic products. But what makes acetone really stand out as we become more environmentally conscious is its exemption as a VOC and HAP. 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. Acetone (67- 64 -1) No No None 12. 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. Acetone is miscible with water and serves as an important organic solvent in its own right, in industry, home, and laboratory. $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. It has a flash point of −18 C (0 F). Your body also produces acetone when it breaks down fat. Acetone is by far the most common exempt VOC. Overall Weight of VOC – Each component in the bucket has a specific weight of VOC in it. VOCs or HAPs per weight of solids. Acetone is a petroleum-derived product. So definitely run your tests. When rel eased into the soil, this material is expected to quickly evaporate. 434-1L-33018 MFG #: 434-1L. Why not just use an EPA VOC-exempt solvent? Again, only the HAPs appear in the numerator, but all of the liquids appear in the denominator.. VOC Calculator 3. Different VOCs have different health effects, and range from those As indicated above, the reduction of VOC content is certainly beneficial to the overall environment. Familiar household uses of acetone are as the active ingredient in nail polish remover and as paint thinner. If this total is less than 1,666 pounds per month, the facility is exempt from needing a … We use a lot of Prime Coatings solvent based paints, and use nothing but acetone to thin.
