DIN EN 923:2016-03 EN 923:2015 (E) 4 Introduction This Eur
19、opean Standard comprises terms peculiar to, or in general use in, the adhesive and adhesive processing industry. The terms defined have been classified so that, as far as possible, related concepts (adhesives, functional adhesive components, chemical base products, adherents, adhesives properties, b
20、onding, and bond properties) are grouped together. All definitions are numbered and an alphabetical index which includes all terms is provided at the end of this European Standard. The numbering of the individual definitions is the same in all three versions (English, French and German) of this Euro
21、pean Standard. Consequently this European Standard can be used as a dictionary, combined with one or both of the other versions as an aid for translation of terms into French or German, as a source of information about related concepts in the adhesive industry or to provide a term for a concept. In
22、order to find: a) the definition of a term: look up the term in the alphabetical index at the end of this European Standard. The index will refer to the number in this European Standard. The definition, the term and any synonyms appear by the number; b) information about related terms: look up the t
23、erm in the alphabetical index to find its number in this European Standard. When the term has been located in this European Standard, the related concepts can be found in the same subdivision; c) the translation of a term into the French or German language: look up the number of this term in this Eu
24、ropean Standard and locate the translation of the term and the definition under the same number in the standard of the foreign version. DIN EN 923:2016-03 EN 923:2015 (E) 5 1 Scope This European Standard defines terms used in the adhesive industry and terms relating to adhesives in those industries
25、that use adhesives. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 Adhesives 2.1.1 adhesive non-metallic substance capable of joining materials by surface bonding (adhesion), and the bond possessing adequate internal strength (cohesion) Note
26、 1 to entry: Many adhesives names refer to their main functional components or the physical nature of the adhesive. Table A.1 lists main binders, temperature and mode of setting of these adhesives and the number of parts that have to be mixed before use. Some other names refer to the method of appli
27、cation, or the mode of setting. Furthermore, adhesives are named according to points of less significance: field of application (e.g. footwear adhesive, construction adhesive, packaging adhesive), material to bond (e.g. paper adhesive, wood adhesive, wall paper adhesive, rubber adhesive), place of a
28、pplication (e.g. in situ adhesive), speed of setting (e.g. instant adhesive), bond properties (e.g. structural adhesive), shape (e.g. powder adhesive, pearl glue, table glue for solid glue, adhesive film for shaped adhesive, or stick adhesive for stick shaped adhesives), or aspect (e.g. white glue).

30、F, PF or PVAC, see 2.3.51, 2.3.52 and 2.3.30 respectively) DIN EN 923:2016-03 EN 923:2015 (E) 6 2.1.4 paste adhesive adhesive of a non-stringy, highly viscous nature Note 1 to entry: Paste adhesives based on starch or cellulose ethers are usually applied for paper bonding (e.g. paper bags or wall pa
31、per). 2.1.5 dispersion adhesive adhesive consisting of a stable dispersion of a polymer in a liquid continuous phase, usually water Note 1 to entry: Dispersion adhesives containing an elastomer as polymer conventionally are often termed “latex”. 2.1.6 emulsion adhesive adhesive consisting of a stabl
32、e emulsion of a liquid hydrophobic resin in water 2.1.7 solvent-borne adhesive solution adhesive solvent-based adhesive adhesive in which the binder is dissolved in a volatile organic solvent 2.1.8 solvent free adhesive adhesive that is substantially free from organic solvents (see 2.1.7) Note 1 to
33、entry: “Substantially free” means that organic solvents have neither been added in the basic elements of an adhesive nor during its process of manufacture out of these basic elements. “Low solvent adhesives” contain at most 5 % of solvents based on total weight of the adhesive. 2.1.9 plastisol adhes
34、ive paste or liquid adhesive material comprising a dispersion of a polymer resin in a plasticizer that when partially heated, gels as the plasticizer is incorporated into the swollen polymer to form a solid system Note 1 to entry: The plastisol will be converted into a solid plastic simply by heatin
35、g to fully fuse. 2.1.10 toughened adhesive adhesive which by virtue of its physical structure discourages propagation of cracks Note 1 to entry: The toughening can be achieved, for example, by the creation of a discrete elastomeric phase within the adhesive matrix. 2.1.11 spray adhesive adhesive tha
36、t is projected in small particles by means of a pressure medium DIN EN 923:2016-03 EN 923:2015 (E) 7 2.1.12 gap-filling adhesive adhesive designed for filling wider gaps between uneven surfaces Note 1 to entry: For high strength load-bearing purposes, e.g. in the car industry, the adhesive will prov
37、ide satisfactory bond strength in bond-lines up to 1 mm in thickness. For the construction industry, high solid adhesives designed for use between uneven surfaces and to bond satisfactorily in gaps up to 6 mm are used. 2.1.13 sealant adhesive material, used to fill gaps where movement can occur in s
38、ervice and which, when set, can accommodate movement Note 1 to entry: The term “sealant” is also used for a material filling a void against the ingress or egress of a fluid, gaseous substance or airborne particles under pressure. 2.1.14 film adhesive adhesive in film form, with or without a carrier
39、Note 1 to entry: Film adhesives set usually by means of heat under pressure. 2.1.15 foaming adhesive adhesive designed to foam in situ, after application, in order to provide extensive gap-filling properties 2.1.16 unsupported film adhesive adhesive supplied in sheet, film or web form, without an in

45、applied separately to adherends Note 1 to entry: Pressing together the components initiates a chemical reaction curing the bond-line. 2.1.25 two way stick adhesive double spread adhesive adhesive that is applied to both adherends 2.1.26 one-component adhesive one-part adhesive adhesive ready for use
46、 Note 1 to entry: A one-part adhesive may require external influences such as heat, humidity, radiation, oxygen firing or the evaporation of solvents for setting. 2.1.27 two-component adhesive two-part adhesive adhesive that consists of two separate reactive components that are mixed before use 2.1.
47、28 multi-component adhesive multi-part adhesive adhesive that consists of two or more separate reactive components that are mixed before use Note 1 to entry: With some multi-part adhesives, the reactive components are applied separated onto both adherends. The curing is going to start after the asse
