(Test Method)Standard Test Method for Resin Solution Dilutability by Volumetric/Gravimetric Determination
Standard Test Method for Resin Solution Dilutability by Volumetric/Gravimetric Determination
SCOPE
1.1 This test method covers both volumetric and gravimetric determination of resin solution dilutability which gives a numerical value for the overall solubility of the resin expressed as percent dilutability.
1.2 This test method is applicable only if the test solution is of sufficient clarity to allow accurate visual judgement of the end point and of low enough viscosity for efficient mixing to take place.
1.3 This test method is primarily for, but not limited to, resins used in the printing ink industry.
1.4 The percent solvent tolerance of a resin can be determined using this test method if the solvent in the resin solution and the dilution solvent are the same.
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.
