Designation:D595899(Reapproved 2012)1Standard Practices forPreparation of Oil-Based Ink Resin Solutions1This standard is issued under the fixed designation D5958;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,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.1NOTEThermometer references and Footnote 5 were editorially corrected in November 2012.1.Scope*1.1 These practices describe laboratory procedures for pre-paring an oil-based ink resin solution in a high-boiling solventusing four pieces of lab equipment;(1)a hot oil bath(Sections4 to 11),(2)a stirrer/hot plate(Sections 12 to 16),(3)an industrial blender(Sections 17 to 22),and(4)a hot air gun(Sections 23 to 27).ASTM Subcommittee D01.37 recommends using the hot oilbath procedure(Practice D5597)where possible.1.2 These practices use laboratory equipment generallyavailable in a normal,well-equipped laboratory.1.3 One or several of these practices allows for rapid resinsolution preparation(under 30 min,typical),can regulate themaximum temperature,can be done under an inert atmosphere,and can prevent the random solvent loss during preparation.1.4 These procedures are for use with ink resins intendedmainly for oil-based offset and letterpress inks.The type ofresins are typically,but not limited to C9aromatic hydrocarbonresins,modified dicyclopentadiene resins,rosin pentaerythritolor glycerine esters,phenolic modified rosin esters,maleicanhydride modified rosin esters,and naturally occurring resinssuch as gilsonite.1.5 The typical high boiling solvents to be used include C12to C16petroleum distillates,2,2,4 trimethyl 1,3-pentanedioldi-isobutyrate,2alkali refined linseed oil,tridecyl alcohol,orcombinations of the above.1.6 To avoid fire or injury,or both,to the operator,thesepractices should not be used with low flash point solvents suchas toluene or xylene.The minimum flash point of the solventsused should be 60C(140F)as determined by Test MethodD56.(WarningUsers of this practice should be aware thatthe flash point of many solvents used for this test(as defined inTest Methods D56 and D1310)is exceeded in the heating cycleof this test method.Take safety precautions since there is thepotential for vapor ignition.Do the methods outlined in ashielded exhaust hood,where there is access to a fire extin-guisher if needed.)1.7 The values stated in SI units are to be regarded asstandard.The values given in parentheses are for informationonly.1.8 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 limitations prior to use.For specific hazardstatement see 25.11.2.Referenced Documents2.1 ASTM Standards:3D56 Test Method for Flash Point by Tag Closed Cup TesterD1310 Test Method for Flash Point and Fire Point of Liquidsby Tag Open-Cup ApparatusD1725 Practice for Preparing Resin Solutions for ViscosityMeasurement by Bubble Time MethodD5062 Test Method for Resin Solution Dilutability byVolumetric/Gravimetric DeterminationD5597 Practice for Preparation of Oil-Based Ink ResinSolutions Using a Hot Oil Bath(Withdrawn 1999)4E1 Specification for ASTM Liquid-in-Glass ThermometersE230 Specification and Temperature-Electromotive Force(EMF)Tables for Standardized Thermocouples3.Terminology3.1 Definitions of Terms Specific to This Standard:1These practices are under the jurisdiction of ASTM Committee D01 on Paintand Related Coatings,Materials,and Applications and are the direct responsibilityof Subcommittee D01.37 on Ink Vehicles.Current edition approved Nov.1,2012.Published November 2012.Originallyapproved in 1996.Last previous edition approved in 2011 as D5958 99(2011).DOI:10.1520/D5958-99R12E01.2The sole source of supply of the plasticizer TXIB known to the committee atthis time is Eastman Chemical Company,/Texas E.M.Division,P.O.Box 7444,Longview,TX 75607-7444.If you are aware of alternative suppliers,please providethis information to ASTM International Headquarters.Your comments will receivecareful consideration at a meeting of the responsible technical committee,1whichyou may attend.3For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.4The last approved version of this historical standard is referenced onwww.astm.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.1 cold cut,ndispersion of resin into solvent using highshear dispersion without external heating.3.1.2 compatibility,nresin an
