VOC emissions, including the emissions fee in Rule 314, are also calculated based on the VOC of material. The only exception is for low solids coatings where the purpose of the coating is not to build film thickness. 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. The VOC limits listed in the Table of Standards (PDF, 35kb) refer to the VOC of coating. Let's explore the three basic percentage problems. The formulas below are all mathematical variations of this formula. You can think of the most basic as X/Y P x 100. This is important because those materials are applied at a certain film thickness so dilution would result in a larger volume of the material being applied to achieve the same film thickness. For conventional solvent based products with no exempt compounds, the two values are always the same.įor waterborne coatings and coatings containing exempt compounds, the VOC of coating is always the higher of the two values. There are many formulas for percentage problems.

All right, let's say I had negative x squared plus 18x, minus 72. And if you really wanted to, you could multiply the negative 1 times this, you would get 3 minus x if you did.

Dilution with water or exempt solvents would reduce the VOC-to-paint-volume ratio while maintaining a constant VOC-to-paint/adhesive-solids ratio. Negative 1 times x minus 3, times x plus 8.

Mounting hardware is included for easily hanging the plaque. Made from sturdy acrylic and featuring an embossed logo and text, the plaque’s stylish design complements a dedicated home theater or living room system. The calculation was derived to express the VOC emitted per volume of coating solids to eliminate the effect of dilution. Show your pride in owning SVS speakers and subwoofer with a handsome SVS Sound REvolution plaque. The regulatory VOC calculates the VOC less exempts and water, which is a more complicated calculation than the actual VOC, in that it subtracts the volume of water and the volume of exempt compounds from the volume of material, in the denominator. The VOC of coating/colorant/adhesive is the same as the term “regulatory VOC,” which is equivalent to the term "VOC, less water and exempts." The VOC of material is the same as the term "actual VOC," which is equivalent to the term "VOC, including water and exempts." There is sometimes confusion over the terms VOC of coating/colorant/adhesive and VOC of material.
