Hot-melt adhesive systems comprise versatile performance hot melts and applicators with auxiliary equipment for continuous use in industry (Figure 8.50). Hot-melt adhesives with 100% solids content have been developed from solvent-free thermo­plastic hot-melt resins. In the molten state, they are capable of wetting a surface and of developing a strong bond by means ofheat dissipation, […]

Postcuring polyurethane hot melts are solvent-free, one-part, moisture-setting adhesives with a solids content of 100%. They rapidly build up strength resulting in a high initial tack (as do conventional hot melts), and this is followed by a postcuring that results in a high structural strength. These adhesives offer good flexibility and resistance to impacts as […]

Cyanoacrylate adhesives are colorless, solvent-free, rapidly polymerizing and cold­setting one-part structural adhesives. The moisture contained in the air initiates curing, while light pressure contact generates a thin film that sets within seconds, making these adhesives particularly well suited for small and plane surfaces. Activators can be employed to accelerate the curing process or to enable […]

One-part and two-part structural adhesives are solvent-free and cured under the effect of heat (one-part adhesives) or at room temperature (two-part adhesives). The curing process oftwo-part adhesives can be accelerated by heat (e. g. a temperature of 65 ° C for 120 min). Structural bond strength can be achieved with versatile high-performance epoxy resin, polyurethane […]

Adhesives and double-sided adhesive tapes provide for a firm connection between dissimilar materials. With one-part and two-part adhesives, structural bond strengths can easily be achieved at room temperature, even on low-energy surfaces such as PE and PP. The adhesives perform tasks that previously were reserved for mechanical joining techniques, such as joining by screws, riveting […]

Adhesive bonding is gaining ground in modern production processes in small-scale industries, handicraft trades and in the do-it-yourself sector. A wide range of products has become available for the adhesive bonding of most different materials under most different conditions and impacts. A wide spectrum of pressure-sensitive rubber-, acrylate — and silicone-based ad­hesives for the purposes […]

Over the past few years, new packaging concepts and materials have brought forth more sophisticated and refined packaging options. A steady increase in the world population and growth in industrial production will have a further growing market impact on the packaging sector that will become even more complex owing to active and intelligent packaging options: […]

Among the multitude of statutory regulations applying to industrial processing, food-law regulations, such as the European Framework Regulation 1935/2004, are of particular importance for packaging adhesives because many packages are used for foodstuffs. A wide array of raw materials is available for the formulation of adhesives that comply with food law requirements, such as the […]

Composting represents another option allowing the material loop of products made from organic materials to be closed. Biological degradation of the material allows the products to be reconveyed to a form that is useful to Nature. Especially in the packaging sector, this is an attractive option, in particular when packages are contaminated with food residues. […]

Today, packages made from plastics are also recycled on a major scale. As with paper recycling, the adhesives used for plastic packaging are required not to disturb the recycling process. As a wide variety of different recycling methods is available for plastics, the adhesives must meet manifold demands. The most established method starts with washing […]
