In present-day high-speed assembly line operations, adhesives are applied robotically. The adhesive bead is apphed quickly and evenly to parts on a conveyor line just prior to being fitted. These operations, especially the need to handle the adhered substrates soon after assembly, demand fast-curing adhesive systems [65]. Two-component adhesives are used to bond metals to plastics in automobiles, to laminate panels in the construction industry, to laminate foams to textiles, to laminate plastic films together, and to bond poly(vinyhdene chloride) films to wood for furniture. A commercial waterborne two-component adhesive is sold by Ashland under the trademark ISOSET. This system is used for exterior sandwich panels by recreational vehicle manufacturers and is composed of a water-emulsiliable isocyanate and a hydroxy-functionalized emulsion latex.

Loudspeaker The loudspeaker as shown in Fig. 2 has eight or so adhesive joints. In order to meet production requirements of one every 10-15 s, it is necessary to use automatically applied fast-curing adhesives. The alternative previously employed was to use... 

The reactions of phosphoric acid esters with epoxy resins have been employed to obtain fast-curing adhesives [42], corrosion-inhibiting coatings [43], fire-resistant materials [44], and high-solids coatings [45-48].

RF resin is also used to make fast-curing adhesives for laminated timber and beams as well as adhesive applications in building construction. 

A different form of RF resin is aiso used to make a fast curing adhesive for iaminated timber, beams, and other adhesive construction appiications. 

Hybrid adhesives, comprised of a polymer adhesive and a synthetic cement, are also used in cartridge injection systems. These are generally fast-cure adhesives and may exhibit superior resistance to high temperatures. 

Adhesives can also stress crack or craze certain plastics and this can also indnce premature failure of the substrate. This generally happens whilst the adhesive is uncured and the plastic part is pre-stressed due to abrupt changes of section. The liquid adhesive softens and weakens the plastic leading to the formation of cracks and the liqnid adhesive then penetrates these cracks causing fnrther damage. With fast-curing adhesives, this is less likely to occur as once the adhesive has cured it is essentially a thermoset plastic (or thermoplastic) itself and is therefore inert. Amorphons thermoplastics are more prone to stress cracking than others and so it is important therefore to ensure that the adhesive is compatible with the substrate. 

Wire tacking, which is the temporary or permanent rapid immobilization of wires at specific locations by touching them to an adhesive drop in the desired location, is a relatively recent innovation in the use of adhesives. The technique, which is widely used with printed circuit boards and other fine wire applications, depends upon fast curing adhesives which develop adequate joint strength in a matter of seconds. Since heat is not required to cure the bond, the technique is ideal for...
