Building Construction Adhesives

The use of adhesives in building construction imposed exacting requirements upon quality and application techniques [92] — [98]. In addition to durability and resistance to mechanical stress, temperature and weather resistance are prime requirements. In prefabricated construction, the use of adhesives was an important requirement for efficient assembly techniques. Adhesives as Additives for Hydraulic Compositions. […]

Floorcovering Adhesives

Flooring adhesives are used for attaching floor coverings to a variety of substrates. The adhesives must develop a strong and durable bond between the floor covering and the substrate. They should not adversely affect coverings, supports and substrates, and after application, should remain odorless and have low emissions. Usually flooring adhesives are applied to the […]

Adhesives for Wallcoverings

Wallcoverings, classified by EN 233-235 [133], consist of a variety of materials: paper, textiles, glass, plastics (PVC, PE, PS, PU), ceramics, wood, cork, metals, leather. They are attached by hand in the form of sheets (wallpapers), tiles, or profiles to masonry, plaster, concrete, plasterboard and gypsum wallboard, wood, and metals. For ease in do-it-yourself projects […]

Bonding of Metals

The adhesives used for bonding metals are preferably reactive adhesives, predom­inantly epoxies, phenolics, (meth)acrylates, polyurethanes, although poly(vinyl chlo­ride) plastisols, MS polymers, and rubber adhesives also are used for elastic bonds [81] — [85]. The range of bond strengths obtainable extends from high-strength, struc­tural bonds (tensile shear strength ca. 40N/mm2) to highly elastic adhesive sealing compounds […]

Bonding of Rubber

Rubben-to-Rubber Bonding. In the bonding of unvulcanized rubber mixtures to one another, there is generally no need to use adhesives when the mixtures to be combined with one another are identical or similar in composition. However, adhesives have to be used for combining different types with one another. Various bonding agents based on halogenated polymers […]

Adhesion of Rubber

Contact Adhesives. Nowadays, rubber solutions based on natural rubber or sty­rene-butadiene rubber, optionally in conjunction with regenerate and depolymerized rubber, are used for large-area bonding where adhesion does not have to meet stringent requirements, as is the case, for example, with the lining of vessels, containers, etc. with rubber. Today, multipurpose adhesives based on polychloroprene […]

Bonding of Elastomers

In the rubber industry, a fundamental distinction is drawn between “bonding” and “adhesion”. Whereas the adhesion of generally vulcanized rubber articles to one another or to metals or plastics is solely a function of the adhesive used, bonding is a process in which vulcanization of the rubber and, at the same time, adhesion between rubber […]

Bonding of Plastics

Plastics are bonded to one another or to other materials. They differ widely in their affinity for bonding. Some plastics are easy to bond (e. g., PVC-U, ABS, PS), whereas others can be bonded only after special preparation (e. g., PTFE). On account of the low polarity and surface tension of certain plastics (e. g., […]

Footwear Adhesives

One of the most important methods of assembling shoe components is adhesive bonding. In 1949 polychloroprene adhesives replaced the nitrocellulose solutions that had been introduced in 1906. The almost complete versatility of the polychloroprenes allowed leather, textiles, and other natural substances (until then the only shoe materi­als) to be supplemented by other materials, such as […]

Gluing of Wood and Wooden Materials

Today for the assembly gluing of wood, for gluing veneers, plastic sheets, and films, and for the manufacture of wood-based materials (chipboard, plywood, hardboard, profiles), synthetic adhesives are used almost exclusively. The traditional use of adhe­sives based on natural products (glutin and casein glues) is confined to a few special cases only (for example, violin […]
