A. Each manufacturer of an adhesive, sealant, adhesive primer or sealant primer subject to this regulation shall display the following information on the product container or label:
1. A statement of the manufacturer's recommendation regarding thinning, reducing, or mixing of the product, provided that:
A. Except as provided in § 44.9(B) of this Part, each person subject to this regulation shall maintain records sufficient to demonstrate compliance with the applicable limitations in § 44.7 of this Part. Such records shall include, as applicable, but not be limited to, the following information for each adhesive, sealant, adhesive primer, sealant primer, cleanup solvent and surface preparation solvent in use or in storage:
B. Any person who complies with § 44.7 of this Part through the use of air pollution control equipment, as specified in § 44.7(E) of this Part, shall record the following information:
E. The composite vapor pressure of organic compounds in cleaning materials shall be determined by quantifying the amount of each compound in the blend using gas chromatographic analysis (ASTM E 260-96) for organics and ASTM D3792-16 for water content, as applicable and incorporated in § 44.4(B) of this Part, and the following equation:
| Where:Ppc = VOC composite partial pressure at 20°C, in mm HgWi = Weight of the "i"th VOC compound, in grams, as determined by ASTM E 260-96Ww = Weight of water, in grams as determined by ASTM D 3792-16We = Weight of the "i"th exempt compound, in grams, as determined by ASTM E 260-96Mwi = Molecular weight of the "i"th VOC compound, in grams per g-mole, as given in chemical reference literatureMww = Molecular weight of water, 18 grams per g-moleMwe =Molecular weight of the "i"th exempt compound, in grams per g-mole, as given in chemical reference literatureVpi = Vapor pressure of the "i"th VOC compound at 20°C, in mm Hg, as determined by § 44.10(F) of this Part |
F. The vapor pressure of each single component compound may be determined from ASTM D2879-10, incorporated in § 44.4(B) of this Part or may be obtained from any of the following sources:
G. If air pollution control equipment is used to meet the requirements of this rule, the owner or operator shall make the following determinations:
I. For adhesives that do not contain reactive diluents, grams of VOC per liter of adhesive, less water, shall be calculated according to the following equation:
| Grams of VOC per liter of adhesive = Where:Ws = weight of volatile compounds, in gramsWw = weight of water, in gramsWe = weight of exempt compounds, in gramsVm = volume of material, in litersVw = volume of water, in litersVe = volume of exempt compounds, in liters |
J. For adhesives that contain reactive diluents, the VOC content of the adhesive is determined after curing. The grams of VOC per liter of adhesive, less water, shall be calculated according to the following equation:
| Grams of VOC per liter of adhesive = Where:Wrs = weight of volatile compounds not consumed during curing, in gramsWrw = weight of water not consumed during curing, in gramsWre = weight of exempt compounds not consumed during curing, in gramsVrm = volume of material not consumed during curing, in litersVrw = volume of water not consumed during curing, in litersVre = volume of exempt compounds not consumed during curing, in liters |
K. Grams of VOC per liter of material shall be calculated according to the following equation:
| Grams of VOC per liter of materials = Where:Ws = weight of volatile compounds, in gramsWw = weight of water, in gramsWe = weight of exempt compounds, in gramsVm = volume of material, in liters |
L. Percent VOC by weight shall be calculated according to the following equation:
| % VOC by weight = Where:Wv = weight of VOCs in gramsW = weight of material in grams |
