“…27,56,[57][58][59][60]63 Paiva et al 55 concluded that to maximize peel strength of the single lap joints leather/TR and leather/PUR joints, it is necessary to apply some surface treatments: on TR -chemical treatment, on leathermechanical treatment and primer and on PU -mechanical treatment and primer. Navarro-Ban˜o´n et al 64 concluded that chemical treatment as surface treatment increases the SBS rubber surface energy and introduced surface roughness, improving the adhesion with PU and PCP adhesive types in upper-to-sole joints. Each material requires the application of a specific surface treatment, as shown in Table 11.…”

“…Paiva et al 55,63 concluded that applying solventbased PU adhesive to bond PU soles to leather upper, the peel strength is capable to satisfy the minimum requirements for the footwear industry, since applied the correct surface treatment. Navarro-Ban˜o´no et al 64 concluded that is possible to obtain good results of peel strength using PU and PCP adhesive types to manufacture SBS/adhesive/leather joints; however, to eliminate the reactivation process with PCP adhesive, it is necessary to use thermoreactive phenolic resin on the formulation.…”

Footwear manufacturing is basically a process of transformation and assembly of various components made up of several materials where different adhesives play a key role, because without them, the shoe would lack shape and structure. This paper aims to understand the importance of adhesives in the footwear industry. It is necessary to identify the different processes in a shoemaking where adhesives are involved and the different adhesive joints produced, as well as their technical requirements. The adhesive joint performance will depend on the different adherends' nature used as footwear materials, the joint design, the surface treatments, the adhesive properties which depend on their formulation, and so on. Adhesive joints in a shoe act under different stress types (peel, shear, tensile, etc.). The most disfavourable are the peel stress. For that reason, the peel strength test is one of the most common to evaluate adhesive joints' performance. When heat resistance is an important adhesive requirements, a creep test is carried out. Furthermore, aging tests are undertaken in order to evaluate durability. This methodology is described in this paper. In the literature, one can find several papers on adhesives, specifically on their mechanical properties. However, there is little research related to footwear applications, including not only the mechanical properties that this industry demands, but also the composition of the adhesives. Therefore, this paper aims to connect the important mechanical properties for the footwear industry with the constituents of the adhesives. However, other properties are also important, such as viscosity, wettability, compatibility, etc., depending on the materials and the adhesive joint type.

“…Styrene-butadiene copolymers (SBC) have a wide field of applications as shoe soles, impact modifiers, asphalt modifiers, adhesives and sealants. Several kinds of SBC have been used in adhesive formulations and as films in adhesives [2,6,7]; however, study of radial structure is not reported before.…”

Nowadays, adhesive industry is growing, and its development will be important in a short future because it offers good returns, and in some cases it is a better option for packaging and sealing with advantages in prices, productivity and weight reduction. In terms of joining and/or sealing, adhesives are well positioned among joining systems; however, knowledge about adhesives is need for their efficient use and only through proper design of the union can be achieved satisfactory results. In this chapter, a development of a formulation of pressure-sensitive adhesive based on styrenebutadiene copolymers using a reactive resin is reported. Non-aromatic solvents were used in adhesive formulation with the aim of avoiding the emission of harmful solvents into the Atmosphere, and the adequate combination and amount of solvents were found. The effect of addition of a phenolic resin in the adhesive formulation as a crosslinking agent was evaluated. By means Fourier Transform Infrared spectroscopy (FTIR), the crosslinking reaction was also studied. The performance of adhesive formulation was evaluated by means of dynamic mechanical analysis (DMA).

“…Cumiloxy radical can experiment beta cleavage to form acetophenone and methyl radical (figure 1). Some reports have use IR for evaluation of grafting surface and evaluation of curing reaction in adhesives reporting that is a useful tool for that kind of studies [12,13]. Also is possible with IR to identify decreasing of peaks attributed to double bonding in polybutadiene backbone when crosslinking process is carry out [14].In this case, radical energy does not reduce significatively, then peroxide eficiency is not alterated, with advantage that methyl radical is not esterically hindranced as initial cumiloxy radical and can participate more effectively in reactions where esteric limitations or diffusion are a limitation.…”

Adhesion refers to a complicated set of interconnected phenomena that is not easy to understand, and by means several semi-empirical tests try to be predicted the strength of an isolated adhesive joint or the strength of a more complex structure, such a laminate, of a fiberreinforcer of particle-filled composite [2]. Adhesives are classified according with common characteristics to facilitate their understanding and use, although no one classification is universally recognized. Classifications include source, function, chemical composition, physical form and application. Within the most used adhesive are natural or synthetic rubber-based materials, usually due its good properties. Based solvent technology in adhesive is one of the most used for wood industry, mainly Polychloroprene, which has high temperature resistance and good paste strength. However, for halogenated compounds generated and for marketing strategy, this material is intended to be replaced by Styrene-Butadiene rubber (SBR) and Styrene-Butadiene-Styrene (SBS) copolymers, and Styrene-butadiene-Ethylene-Styrene (SEBS).
