1、Designation:D595899(Reapproved 2020)Standard 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 revisio
2、n.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 These practices describe laboratory procedures for pre-paring an oil-based ink resin solution in a high-boiling solventusing four piece
3、s of lab equipment:(1)A hot oil bath(Sections 4 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 us

5、ng 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
6、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.
7、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 poi
