(Specification)Standard Specification for Epoxy Resins
Standard Specification for Epoxy Resins
ABSTRACT
This specification covers totally reactive epoxy resins supplied as liquids or solids that can be used for castings, coatings, tooling, potting, adhesives, or reinforced applications. The epoxy resins described also can be used as stabilizers and cross-linking agents; and they can be combined with other reactive products. The resins covered contain no hardeners. The six resin types covered in this specification are divided into specific groups by their chemical nature. The materials shall conform to the required viscosity, Mettler softening point, and color.
SCOPE
1.1 This specification covers totally reactive epoxy resins supplied as liquids or solids which can be used for castings, coatings, tooling, potting, adhesives, or reinforced applications. The addition of hardeners in the proper proportions causes these resins to polymerize into infusible products. The properties of these products can be modified by the addition of various fillers, reinforcements, extenders, plasticizers, thixotropic agents, etc. The epoxy resins described also can be used as stabilizers and cross-linking agents; and they can be combined with other reactive products.
1.2 It is not the function of this specification to provide engineering data or to guide the purchaser in the selection of a material for a specific end use. Ordinarily the properties listed in Table 1 and Table 2 are sufficient to characterize a material under this specification, and it is recommended that routine inspection be limited to testing for such properties.
1.3 The values stated in SI units are to be regarded as standard.
Note 1: ISO 3673–1:1980(E) is similar but not equivalent to this specification. Product classification and characterization are not the same.
1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
