Aqueous emulsions of polymeric compounds, e. g., homopolymers of vinyl acetate and vinyl propionate, vinyl acetate copolymers with ethylene or maleic esters; polyacrylic esters, styrene copolymers. Uses: paper, wood, also bonding to plastics.

Solutions of polymeric, natural, and/or synthetic substances in organic solvents, e. g., vinyl polymers, natural rubber, synthetic rubbers of low polarity. Uses: paper, plastics, silicate-containing materials, wood. Solutions of natural and synthetic high molecular mass substances in water, e. g., starch, dextrins, casein, cellulose ethers, water-soluble derivatives of poly(acrylic acid), poly(vinyl alcohol), poly(vinyl pyrrolidone) (adhesive […]

Heat-Sealing Adhesives and High-Frequency Welding Auxiliaries, e. g., vinyl polymers. Uses: paper, plastics, lamination of plastic films to metal foils (packaging, metal-foil lamination). Contact Cements: elastomers (e. g., polychlorobutadiene) in conjunction with adhesive resins (e. g., alkylphenol or modified phenolic resins); bonding is obtained by contact under pressure between two almost dry adhesive layers. Uses: […]

Adhesives can be classified on the basis of chemical composition [29], setting mechanism [30], and adhesion mechanism as pressure-sensitive, adhesion, and diffu­sion adhesives [31]. Lucre [32] proposed a flexible classification in which each adhesive is characterized and classified according to various characteristic features, such as chemical basis, form of application, application temperature, thermal behavior, and […]

The adhesives industry uses many different products of natural and synthetic origin. These are mainly raw materials that are produced in large quantities and hence at reasonable prices. Raw materials that are used solely or primarily for adhesives are relatively rare or, alternatively, represent special types within fairly broad production programs. Basic raw materials are […]

Some of the terms are defined in DIN 16920 [24] and EN 923 [132]. Adherent: a body that is or is intended to be bonded to another body. Adhesion: state in which two surfaces are held together by interfacial bonds. Adhesive application: the application and distribution of an adhesive over the surface to be joined. […]

The atoms or molecules in any solid are held together by so-called cohesion forces. These interatomic and intermolecular forces are conservative in character, i. e., not dependent upon the pretreatment of the material [4, p. 1]. After a break in the solid, the two fragments cannot be put back together in such a way as […]

Adhesives are defined as nonmetallic substances capable of joining materials by surface bonding (adhesion), the bond itself possessing adequate internal strength (cohesion). Adhesive is a generic term and covers other common terms, such as glue, paste, gums, adhesive cement, and bonding agent. History. Adhesion is among the oldest technologies of mankind [129]. As early as […]

The impressive developments in numerous fields of technology — anything we can imagine from bookbinding, food packaging, electronic devices, automobile manufac­ture to building and aircraft constructions — all engeneering progress in these and other areas is enabled and accelerated by innovations in adhesive technology. Although adhesive applications mostly are not readily evident in daily life […]
