Approximately 12 billion litres of paints are produced annually. 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. (August 6, 2011). These surfaces will scatter light more inconsistently, which is often detected as uneven sheen, glossy peaks & flat troughs, patchiness, lapping or just an uneven “dry looking” appearance. It is possible to switch to a lower VOC coating from a higher VOC coating only to find you have moved from a compliant coating to a non-compliant coating. A coating with a VOC content reported by the manufacturer as 3.44 lb/gal is selected for use in a dip tank. Since this coating's VOC content of 3.45 lb VOC/gal is less than the allowable value of 3.49 lb VOC/gal, this coating complies with the requirements for air-dry coatings.

A number of our products are formulated to meet these criteria. Not all solvents have this density, however. In the world of VOCs the number on the product label or MSDS does not always tell the whole story. Recycled Content Paint. The foregoing discussion primarily serves to make the following point. Like HAPs, TACs can be found in both the liquid and solid portions of coatings. #pollutioncontrol. Although it was prepared for finishers in Pennsylvania, it may be applicable to many finishers across the country who want to calculate their maximum allowable VOC content. This is the maximum amount of VOC per unit volume of solids that the standard air-dry coating may contain. "An Introduction to Indoor Air Quality." We've found innovative ways to make coatings that are compliant in the most stringent regulatory requirements. To determine whether or not this is a compliant coating, first solve for the present coating's solvent density: 3.44 (lb VOC (solvent) ÷ gal of coating) x (1 gal of coating ÷ 0.5237 gal of solvent) = 6.569 lb/gal of solvent. "VOC regulatory" is the same as the term "VOC coating" used in many local air district rules, which is equivalent to the term "VOC, less water and exempts." If one component in the mixture has a higher VOC content, or is added in a higher quantity than the others, We also share information about your use of our site with our social media, advertising and analytics partners who may combine it with other information that you’ve provided to them or that they’ve collected from your use of their services. Health.state.ny.us. Brands such as Backdrop, Clare, Behr, Sherwin-Williams, Farrow & Ball, and more have hopped on the bandwagon. Recycled content paints are not covered by this specification. The U.S. government now limits the amount of VOCs to 250 grams per liter for flat finishes and 380 for … 3. In the chemical industry, low VOC is used to describe a product with VOC content at or below 150 g/L. Low solids coatings, which are defined as coatings containing less than one pound of solids per gallon of coating, are regulated by the VOC of material. Paint with less than 250 grams of VOCs per liter is considered low-VOC paint [source: Midwest Eco-Design]. Copyright © Masking is employed in most any metal finishing operation where only a specifically defined area of the surface of a part must be exposed to a process. As a practical example for air-dry coatings, the VOC limit in Table I is 3.5 lb/gal. Calculating the maximum allowable VOC content adjusted for solvent density... VOC emissions, including the emissions fee in Rule 314, are also calculated based on the VOC of material. However, this coating has a volatile content of 47.05 pt by volume and a solids content … The picture below shows the VO… Consumerreports.org, April 2, 2008. http://news.consumerreports.org/home/2008/04/vocs-in-paint.html. VOC Actual – sometimes labeled ‘Material VOC’, ‘Total VOC’, or ‘Emitted VOC’ VOC Regulatory – sometimes labeled ‘VOC content less water and exempt compounds’, ‘VOC as applied’, or ‘VOC EPA Method 24’ Percent Water and Exempt Compounds A complete application will have at least two of the above three pieces of Epa.gov. By setting the pct reduction to zero in the equation and arranging the equation, one can determine x as follows. Meeting and Exceeding Standards and the Toughest VOC Regulations. VOCs are emitted by a wide array of products numbering in the thousands (EPA, Environmental Protection Agency “Volatile Organic Compounds’ Impact on Indoor Air Quality” 2017). Information about the device's operating system, Information about other identifiers assigned to the device, The IP address from which the device accesses a client's website or mobile application, Information about the user's activity on that device, including web pages and mobile apps visited or used, Information about the geographic location of the device when it accesses a website or mobile application. A wide selection of our products meet VOC guidelines for industrial and architectural applications. Illinois enacted New VOC (Volatile Organic Compounds) regulations for paints that went into effect on 7/1/09. VOC content = (VOC percent by weight/100) x density = (40 /100) x 7.00 lb/gal = 2.80 pounds per gallon Sometimes the VOC content is provided in volume percent. Clare Paint.  2020, The Voice of the Finishing Industry since 1936, Learn What’s Coming for Finishing Technology, Trends in Automotive Manufacturing Knowledge Center, Color and 3D Topography Analyzer Evaluates Surface Structure, Paint Application Without Atomizer Eliminates Overspray, Dialing in Chemistries for a New Washer System, Dürr Partnership Expands Market Access for EV Batteries. These regulations are similar to those that have been implemented in the The Ozone Transport Commission (OTC) regions. http://www.health.state.ny.us/environmental/indoors/voc.htm, "What are VOCs in paint, and is more or less of them better?" If I have a gas leak in my home, will I die? This means that the solids volume percentage in the coating would have to be at least 49.61 pct in order to be in compliance. Consumerreports.org, March, 2009. http://www.consumerreports.org/cro/magazine-archive/march-2009/home-garden/interior-paints/overview/interior-paints-ov.htm, "Paint." You consent to our cookies if you continue to use our website. Even though the actual VOC content of the coating is less than 3.50 lb/gal value, it is not a compliant coating because it does not meet the adjusted maximum allowable VOC content of 3.31 lb/gal. In coatings, the solvents containing VOCs assist with the quality of application and drying, so that a substance like paint does not streak on a surface. Check solvent density and/or solids volume ratio as well as VOC content then evaluate the compliance status of a coating. They can be present in paints, coatings and cleaning products. Since the solids content of the coating is only 47.63 pct, this coating is not in compliance. Maximum allowable VOC content at standard solvent density. Over the last several years, EPA and several states have also issued regulations that establish VOC-content limits for many types of paints and coatings. Better adhesion, enhanced corrosion and blister resistance, To determine the allowable VOC content, corrected for non-standard solvent density, one must use Equation 1. For example, to earn maximum credits as a low-emitting interior material, flat paint must meet a VOC level of 50 g/L or less and be emissions-certified. In such a case if the weight percent of solids is given, you can calculate the VOC content by the difference of the total and solids weight percent. Because it emits fewer fumes than a traditional pick might, low-VOC paint is a safer option—and you don’t have to sacrifice a great wall color to use it. 10 Dangerous Everyday Things in Your Home. Equation 1 is formulated to solve for the pct reduction required by a control method when using a coating with VOC content greater than that specified in Table I. Certain VOCs are harmful when inhaled and may pose indoor air quality concerns. (Maximum allowable VOC content at coating's solvent density. (August 6, 2011).http://www.epa.gov/iaq/voc.html, "How long does it take for VOCs to dissipate?" Note that this solvent density is less than the standard of 7.36 lb/gal. To achieve LEED v4 accreditation for the same products, however, VOC emissions and VOCs must also be taken into consideration. The most prevalent VOC is ethane, a relatively inert compound. ), (Found in Table I. The directive also requires that suppliers label the subcategory of the product, the legal limit value for VOC contents and the maximum content of VOC of the product in its ready to use condition. How long paint releases VOCs depends on the type of paint, the surface being painted, and the climate. When it comes to paint, VOCs are often added for better open time and freeze-thaw resistance and are emitted as gasses from liquids that evaporate as paint dries. The complete listing of the toxic air contaminants regulated … These values are based on a standard solvent density of 7.36 lb/gal. The result is a value of 3.31 lb/gal, the maximum allowable VOC content for the present coating adjusted for its solvent density. Low-VOC or zero-VOC paints typically contain VOC content of less than 5 grams per liter. Conversely, masking may be employed on a surface where treatment is either not required or must be avoided. Even though less than 3% of all man-made VOCs in Europe (and less than 1% in the UK) come from decorative paint, we have long implemented a voluntary industry agreement for carrying out VOC reductions in products and for displaying VOC content information on product labels. Green Programs and VOC Regulated Areas Specifications Paints with no VOCs have no volatile organic compounds in them. However, this coating has a volatile content of 47.05 pt by volume and a solids content of 52.95 pct by volume. However, they can cause respiratory and other health problemsfor occupants, when used indoors. That's not to say they don't contain any harmful chemicals, though. According to Equation 3, the maximum allowable VOC content for this particular coating is 3.49 lb VOC/gal of coating. Like many healthier alternatives, no- and low-VOC paint usually costs more (about 20 to 80 … VOCs are carbon-containing ingredients that can have effects on those exposed to high concentrations of VOCs – the lower the VOC level, the better it is for th… The move to low VOC paints means that application and drying properties can differ significantly from what the user is accustomed to, hence ne… Ultra-low-VOC products have VOC content that's below 50 … VOCs are Volatile Organic Compounds. The solvent density is 3.45/0.4705 = 7.33 lb/gal. A second coating has a reported VOC content of 3.45 lb VOC/gal of coating, which is slightly greater than the first coating. Low-VOC and no-VOC paints have entered the market but even these paints are not truly free of VOC compounds; a paint without a VOC drying agent will often still have a (sometimes significant) VOC content based on other ingredients like the pigment that is added at the point of sale. and reduced coating-part interactions make pretreatment a must. The right-hand side of Equation 4 may be regarded as the maximum allowable VOC content of a coating divided by the minimum required volume fraction of solids in a standard coating. Substituting units into Equation 4 results in this: {(lb VOC÷gal coating)÷(1-((lb VOC÷gal coating)÷(lb VOC÷gal solvent))} = {(lb VOC÷gal coating)÷(1-((lb VOC÷gal coating)÷(lb VOC÷gal solvent))}, (lb VOC÷gal solids) = (lb VOC÷gal solids). No VOC . Amount of Coating Used – 4,000 gallons VOC Content – 2.11 lbs/gallon 4,000 gallons x 2.11 lbs/gallon = 8,440 lbs of VOC = 4.22 tons of VOC What if only weight % is … Next, place these values in Equation 3 and solve for x: z1 = 6.569, y = 3.50 and z2 = 7.36. For all coatings used in air-dry applications, Thus, the minimum required volume percentage of solids in a standard coating for air-dry application is 52.45 pct. VOC charts for PPG Refinish brands are found on each brand's web page: Automotive Refinish Products. Paint Over It: If your previous paint job is more than 5 years old, you may choose to just paint over it with low or zero VOC paint. The left-hand side of Equation 4 represents the lbs of VOC per gal of solids allowable in the present coating that has non-standard solvent density (and also non-standard solids volume fraction). The VOC of Mixture is a number that accounts for the following in a mixed coating: - The VOC content of each component in the coating - The amount of each component in the coating It is essentially a weighted average for the entire coating. The federal government caps the VOC content in paint at 250 grams per liter (g/l) for flat finishes and 380 g/l for other finishes (low-luster, semigloss, etc.). You can get any color your heart desires in low- or no-VOC paint! Paint manufacturers are required to print the amount of VOCs on the paint can itself, so a little sleuthing at your local paint store will go a long way. 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. Under LEED 09, paint and other building materials were addressed and evaluated according to volatile organic compounds (VOCs). ), z2lb VOC (standard)÷gal of standard solvent, (Or standard solvent density of 7.36 lb/gal).
