Significance and Use |
3.1 The nonvolatile content of resin solutions is useful to coatings producers and users for the determination of the total solids available for film formation and for the estimation of the volatile organic content. |
1. Scope |
1.1 These test methods cover the determination of nonvolatile content of solutions of resins in volatile organic solvents. 1.2 Two test methods are included as follows: 1.2.1 Test Method A—For solutions of non-heat-reactive resins. These solutions contain resins that remain stable and release the solvent under conditions of the test. Examples are ester gums and alkyds. 1.2.2 Test Method B—For two types of solutions: 1.2.2.1 Solutions of heat-reactive resins. These solutions contain resins that undergo condensation or other reactions under the influence of heat. Examples include the formaldehyde reaction products of urea, melamine, and phenols. 1.2.2.2 Solutions that release solvent slowly. Examples include epoxy resin solutions. 1.3 Test Methods A and B differ primarily in the drying times and types of oven used. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
