1、Designation: D5201 05a (Reapproved 2010)Standard Practice forCalculating Formulation Physical Constants of Paints andCoatings1This standard is issued under the fixed designation D5201; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision
2、, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This practice covers procedures commonly used in thepaint industry to formulate paints and coating mate
3、rials. Itdescribes procedures for calculating formulation values forweight solids, volume solids, solvent content, volatile organiccompound (VOC) content, hazardous air pollutant (HAP)content, and density of liquid paints and coatings. These valuesare calculated from basic formulation data. These ca
4、lculationsmay be related to either as-supplied (unreduced) or as-applied(reduced) coating materials, including multicomponent types.1.2 These calculated, formulation-based values may or maynot be acceptable for VOC regulatory purposes, depending onthe specific wording of the applicable regulation. S
5、ome regu-lations require analysis of the coating. Some rules allow the useof formulation data, however, some adjustments may beneeded to the values calculated in this practice before they areused for regulatory purposes (see 4.3).1.3 For purposes of this practice, it is assumed that volatilecomponen
6、ts evaporate and the materials that remain areidentified as coating solids. For example, solvents are normallyused to adjust viscosity for application and appearance of thecoating. Other liquid materials, such as plasticizers, reactivediluents, etc., that are expected to be retained in the dried fil
7、mto affect the final physical properties should be classified aspart of the coating solids. Standards such as Test MethodsD2369, D4758, D5403 and Guide D2832 may be used todetermine volatile or nonvolatile content of specific compo-nents. For purposes of this practice it is assumed that theblended f
8、ormulation behaves as an ideal solution with novolume change on mixing (see 6.2).1.4 Volatile by-products of cross-linking reactions (curevolatiles) are not considered in these calculations since theobject of this practice is to define paint physical constantsbased on formulation information. Variat
9、ions in raw materials,variations in the production processes, test methods, and testmethod accuracy are not taken into account in these calcula-tions.1.5 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that
10、are provided for information onlyand are not considered standard. However, they may be readilyconverted into SI units, if required by the user (for example,see Note 4).2.
