Designation:D176300(Reapproved 2021)Standard Specification forEpoxy Resins1This standard is issued under the fixed designation D1763;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This specification covers totally reactive epoxy resinssupplied as liquids or solids which can be used for castings,coatings,tooling,potting,adhesives,or reinforced applica-tions.The addition of hardeners in the proper proportionscauses these resins to polymerize into infusible products.Theproperties of these products can be modified by the addition ofvarious fillers,reinforcements,extenders,plasticizers,thixo-tropic agents,etc.The epoxy resins described also can be usedas stabilizers and cross-linking agents;and they can becombined with other reactive products.1.2 It is not the function of this specification to provideengineering data or to guide the purchaser in the selection of amaterial for a specific end use.Ordinarily the properties listedin Table 1 and Table 2 are sufficient to characterize a materialunder this specification,and it is recommended that routineinspection be limited to testing for such properties.1.3 The values stated in SI units are to be regarded asstandard.NOTE1ISO 36731:1980(E)is similar but not equivalent to thisspecification.Product classification and characterization are not the same.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)D883 Terminology Relating to PlasticsD1209 Test Method for Color of Clear Liquids(Platinum-Cobalt Scale)D1544 Test Method for Color of Transparent Liquids(Gard-ner Color Scale)D1652 Test Method for Epoxy Content of Epoxy ResinsD3104 Test Method for Softening Point of Pitches(MettlerSoftening Point Method)D3892 Practice for Packaging/Packing of Plastics2.2 ISO Standard:3ISO 36731:1980(E)PlasticsEpoxy ResinsPart 13.Terminology3.1 Definitions:3.1.1 GeneralDefinitions of terms used in this specifica-tion are in accordance with Terminology D883.4.Classification4.1 The resins covered contain no hardeners.Resin typescovered are divided into specific groups by their chemicalnature:4.1.1 Type IBisphenol A and epichlorohydrin.4.1.2 Type IIReaction product of phenol and formalde-hyde(novolac resin)and epichlorohydrin.4.1.3 Type IIICycloaliphatic and peracid epoxies.4.1.4 Type IVGlycidyl esters.4.1.5 Type VReaction product of epichlorohydrin andp-aminophenol.1This specification is under the jurisdiction of ASTM Committee D20 onPlastics and is the direct responsibility of Subcommittee D20.16 on ThermosettingMaterials.Current edition approved July 1,2021.Published July 2021.Originally approvedin 1960.Last previous edition approved in 2013 as D1763-00(2013).DOI:10.1520/D1763-00R21.2For 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.3Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.14.1.6 Type VIReaction product of epichlorohydrin andglyoxal tetraphenol.4.2 These types may be further subdivided by grades:4.2.1 Grade 1Resins containing no diluent.4.2.2 Grade 2Resins modified with a reactive diluent.Each class of Grade 2 resin can be made from any class ofGrade 1 resin.4.2.3 Each grade may include as many classes as are shownin the tables.5.Requirements5.1 The resin shall be of uniform quality and as free ofcontamination as c
