Then add up the VOC emissions from all the coatings and solvents used to calculate total VOC emissions in pounds per month. The following analysis will be limited to coatings containing no water and no exempt solvents. A coating with a VOC content reported by the manufacturer as 3.44 lb/gal is selected for use in a dip tank. 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. the waterborne coatings provided better coverage and resulted in the use of a smaller volume of coating … ATTACHMENT I Given the mass of VOC and mass of exempt solvent per unit volume of coating, determine the mass of VOC per unit volume of coating less exempt solvent. Calculating VOC of Coating, Less Water and Less Exempt Solvent. Acetone is on the Federal exempt solvent list - not just California. Consider these examples: • HCFC-225 is a VOC-exempt degreasing solvent proven to be an effective cleaner with good materials compatibility. This confuses the categorization of chemical compounds and blends as “VOC-exempt … An exempt solvent is a particular type of solvent that falls below specific safety criteria. Thanks, I really need this info!

However, there are very few options that deliver high performance while meeting VOC and other EHS requirements. solvents directly related to the process, such as gun or applicator cleaning for coating operations. So, if you aren’t yet manufacturing or selling low-VOC products, now is a great time to start. content of 25 g/l or less. The density of the exempt solvent is 1.3 kg per liter. As VOC-exempt solvents, these materials may be used in coatings, but are excluded from the weight aggregation of total VOC although, like water, their volume must also be excluded from the VOC calculation. The low VOC content of an adhesive is very dependent on VOC exempt solvents. VOC Content and VOC Exemption Rules. It is not used for emission calculations. Some coatings contain water as a solvent and/or some amounts of exempt solvents. I provided several sample calculations. o 12-month organic HAP emission rate (Options 2 and 3). VOC content expressed as the Mass of VOC per Unit Volume of Coating Less Water and Exempt solvents (pound per gallon or grams per liter) ASTM Practice D3960 - Standard Practice for Determining Volatile Organic Compound (VOC) Content of Paints and related coatings. WHAT IS LOW VOC AND WHAT ARE THE BENEFITS? VOC per unit volume of coating less exempt solvent and water. Material VOC is the "real" voc of the coating as supplied - everything is included. Attached is a memorandum dated February 26, 1981, from David Salman, Chemical Applications Section, Chemical Petroleum Branch, to James Berry, Chief, Chemical Applications Section, Chemical Petroleum Branch, Emission Standards and Engineering Division. Many states defer to the South Coast Air Quality Management District of California (the air pollution regulator for the Los Angeles basin) for VOC content limits. Other LVP-VOC propylene glycol ethers include Glycol Ether DPNB and Glycol Ether TPNB. o Total volume of coating solids used each month (Options 2 and 3). Low VOC Solvents Home Specialty ingredients Solvents Low VOC Solvents. Attachment I Given the mass of VOC and mass of exempt solvent per unit volume of coating, determine the mass of VOC per unit volume of coating less exempt solvent. In addition to calculating coating VOC content as applied on a per gallon of coating basis, many State and federal rules require that the as-applied coating VOC content be determined on a per gallon of coating basis, less water and exempt solvent. A.

All voc exempt solvents wholesalers & voc exempt solvents manufacturers come from members. In certain instances, there are solvents that do not entirely comply with the safety use standards, but are still permitted for use. In commercial and regulatory applications, the pounds of VOC per gallon of coating less water and exempt compounds is calculated from the measured loss of weight and the exempt compound and water content of the coating. 0.2 1 - ----- = 0.3 kg of VOC per liter of coating less 0.4 exempt solvent 1 - --- 1.3 Note: The term VOC as used above means reactive VOC only. In coating materials of less than 1 pound of solids per gallon the material VOC is used. However, SCAQMD Rule 102 includes VOC-exempt products which may or may not be listed as VOC-exempt by the EPA. printing, surface cleaning, vehicle coating, dry cleaning and manufacture of footwear and pharmaceutical products. The VOC Solvents Emissions Directive is the main policy instrument for the reduction of industrial emissions of volatile organic compounds (VOCs) in the European Union. Choosing less toxic alternatives for solvents keeps you safe and helps to keep harmful substances out of our environment. A: An exempt solvent is a volatile organic compound that does not participate in an atmospheric photochemical reaction to form smog. Other terms to describe it include volatile organic compound (VOC) exempt. the mass of VOC per unit volume of coating less exempt solvent and water. Additionally, solvents with certain positive environmental and performance characteristics (i.e. Could you please show me how to calculate VOC's with a sample formulation for solventborne and waterborne coatings. 3 (Footnote 3). VOC content, less exempt solvents: This is the value needed to determine if the coating complies with a regulatory formulation limit, e.g., 3.5 lbs VOC/gallon. EPA's Reference Method 24A is applicable to the determination of VOC content and density of solvent-borne (solvent-reducible) printing inks and related coatings. Modern solvents with water or soy as a base are often good options. When adhesives have 400-540 grams solids content per liter of VOCs the only exempt solvent used is acetone whereas in the composition of the present invention in order to reduce the VOC content two VOC exempt solvents, namely acetone and methyl acetate, are used. 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. 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. Search through these databases to find more information on solvent substitutions: CleanerSolutions is a general solvent substitution database. Q. Calculating Emissions from Coating and Painting Operations P a g e | 5 What is a compliant coating? I have seen the calculation formula but I never get the same value as the mfr shows on their formulation. Note: the conversion factor to convert grams per liter to pounds per gallon is 120 (Divide G/L by 120 to get Lbs/Gal). The coating also has a reported volatile solvent content of 52.37 pct by volume, which implies a solids content of 100 - 52.37 = 47.63 pct by volume. For Coating VOC (sometimes called Regulatory VOC) the water and exempt solvent are subtracted and the VOC is calculated on the remainder. We doesn't provide voc exempt solvents products or service, please contact them directly and verify their companies info carefully. 3 z = ----- = 3.7 pounds of VOC per gallon of coating 2 less exempt solvent 1 - -- 11 Example 2 - Each liter of coating contains 0.2 kg of VOC and 0.4kg of exempt solvent.

What does “VOC per gallon, less water and Federally exempt solvents” mean? PC is a less aggressive solvent in certain I&I applications, but it is highly Coating VOC Content Less Water and Exempt Solvent . It can be an organic solvent but it takes so long to react with nitrogen oxides (NOx) in the presence of sunlight that the EPA considers its reactivity to be negligible. voc exempt solvents. When a solvent is said to be "exempt," it qualifies or is exempted. EPA regulations typically limit the amount of VOC per gallon of coating, excluding water and exempt solvents. Thus, the 55% decrease (from 5.70 to 2.58) in VOC content calculated by the "per-pound-ofsolids" method reflects the actual reduction in VOC emissions obtained by using a VOC-exempt solvent. Manufacturers are also facing pressure to reduce flammability, toxicity and GWP. It covers a wide range of solvent using activities, e.g. Eastman solvents and coalescents that qualify as LVP-VOC in the U.S. Regulatory authority. Use less toxic solvent alternatives.
