The g/L less water and VOC exempt solvent approach comes from the U.S. regulatory scheme. Back in the 1970s at the beginning of coatings VOC regulation, the USEPA was concerned that house paint manufacturers would simply dilute their products to reduce VOC content and direct users to apply heavier

100.0%. Organic Volatiles. 0.0%. 0.0%. Percent Non-Volatile. 0.0%. 0.0%. VOC Content. LB/Gal g/L. Total. 0.00. 0. Less exempt solvents.

To calculate the weight of total VOC you will need to go to the MSDS and list the density of each VOC ingredient and convert each one from volume to weight. However, the vendor is obliged to tell you the VOC by weight per EPA Method 24. That is the only method that is legally acceptable and you should not need to perform any caluclations.

SCAQMD generally lists paints in terms of grams per liter VOC content. I have seen several paint manufacturers listing VOCs in other formats 

12/21 · It happened that the VOC content (EU) are 0% (w/w), which I'm pretty sure it's the same as 0 g/L , is it correct? And some MSDS also stated VOC content in lbs/gal, which we

Under current regulations, there are two ways of determining the VOC content of a coating: (1) in pounds (or grams) of VOC per gallon (or liter) of solution 

1) Except as provided in paragraph (2) for single-ply roof membrane, use materials containing VOCs for surface preparation, unless the VOC content of the surface preparation solvent is less than 70 grams per liter of material or 0.6 pound of VOC per gallon of material.

Comparison of VOC content of a Conventional Lacquer with that of a 275 G/L VOC (or Waterborne) Lacquer V.O.C. is defined as Volatile Organic Compound (which is almost all solvents) - and it is expressed as a ratio of weight to volume (e.g. pounds per gallon or grams per liter).

According to experts, a level of 0.3 to 0.5 mg/m3 is safe. Do VOCs in paint go away? Most Volatile Organic Compounds dissipate very quickly from 

Under current regulations, there are two ways of determining the VOC content of a coating: (1) in pounds (or grams) of VOC per gallon (or liter) of solution minus exempt solvents (including water and VOC-exempt organic compounds); or (2) in pounds of VOC per pound of solids, as applied. These two methods ar See more

9/1 · A calculated VOC target of less than 25 g/L was achieved by using 3% dipropylene glycol n-butyl ether (DPnB) along with 2% plasticizer, both based on polymer solids. A maximum of 3% volatile coalescent must be used to maintain the calculated VOC level under 25 g/L.

a) sets limits on the voc content of 172 types of products including 51 types of architectural paints/coatings, 7 types of printing inks, 6 broad categories (15 types) of consumer products, 14 types of vehicle refinishing paints/coatings, 36 types of vessel and pleasure craft paints/coatings and 47 types of adhesives and sealants, fountain

Majority of SealantDirect sealants and adhesives are considered to be “Ultra-Low VOC” as they have VOC content below 50 g/L. A product that is lower in VOC 

VOC content of each coating, thinner and other component as supplied. (3) The VOC content of each as applied coating. (d) The solvents methyl chloroform (1,1,1-trichloroethane) and methylene chloride are exempt from control under this section A

Volatile organic compounds (VOCs) are organic chemical compounds which can quickly evaporate to air due to their high vapour pressure and low boiling point. Common VOCs include ethanol, formaldehyde, benzene, toluene and xylene. VOCs are of concern to both indoor air quality and outdoor quality.

MPI Green Performance® Standard (GPS-2-12) provides for a maximum allowable limit of 50 g/L of VOCs. VOCs shall be listed as g/L (grams/liter). The calculation 

VOCs are common ground-water contaminants. Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors.

9/24 · In general, the term “low VOC” describes a solvent whose VOC content is at or below 150 g/L. A solvent that has low VOC content usually isn’t as safe as one that has no VOCs.

VOC emissions, including the emissions fee in Rule 314, are also calculated based on the VOC of material. The VOC Calculator (XLS, 90kb) is a spreadsheet that will calculate both VOC values based on the solids, water content and density of the material. Sample Coating Calculation: Density= 0.99 g/mL Water= 50% by weight Density of water= 0.997 g/mL

10/25 · When it is all said and done, the VOC content is a multi-faceted number for the content in a product that someone is concerned might evaporate into the air and that could pose some degree of health concern. Typical application: Paint, coatings, adhesives, cleaners, air fresheners etc. VOC emission doesn't seem all that different on the surface.

MPI Green Performance ® Standard (GPS-2-12) provides for a maximum allowable limit of 50 g/L of VOCs. VOCs shall be listed as g/L (grams/liter). The calculation of VOC shall exclude water and tinting color added at the point of sale.

However, most low-VOC paint will have a VOC content of no more than 50-150 g/L, and most paint manufacturers that sell low-VOC paints do

Define VOC content. means the total weight of VOC in a product expressed as a percentage of the product weight (exclusive of the container or packaging), as determined pursuant to sections 94515(a) and (b). Adhesives shall have a VOC content of 70 g/L or less when calculated according to 40 CFR 59, Subpart D (EPA Method 24).
