Where: PVF = The as-applied monomer VOC emission rate for the filled production resin or tooling resin, in kilograms monomer VOC per megagram of filled material.
PVU = The monomer VOC emission rate for the neat (unfilled) resin before filler is added, as calculated using the formulas in Table 2 of Section 3(B)(3) of this Chapter.
%Filler = The weight-percent of filler in the as-applied filled resin system.
