1、Designation: D6887 03 (Reapproved 2013)Standard Test Method forTesting Alkyd Compatibility with Resin or Resin Solutions1This standard is issued under the fixed designation D6887; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the

2、 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. Scope1.1 This test method covers the procedure for determiningthe degree of compatibility of an alkyd with a specific

3、resin orresin solution.1.2 The most common use of this method is to test alkydcompatibility with a hydrocarbon resin or a solution of theresin in an aliphatic solvent, for lithographic ink vehicleapplications.1.3 The values stated in SI units are to be regarded asstandard. No other units of measurem

4、ent are included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitat

Summary of Test Method4.1 The required resin to alkyd ratio is mixed into a 150-mLbeaker and heated to 160C until clear and homogenous.4.2 The solution is placed into pre-labeled jars

Significance and Use5.1 Incompatibility of the system can lead to loss of gloss,decreased color strength, rheological problems and grind issuesin the flush or pigment base.5.2 This method is us

All laboratories agreed on the compatibility/incompatibility of each hydrocarbon resin with each alkyd.However, s
