Handbook of adhesive technology

These adhesives are used as additives to other materials to form adhesives for glass and metals, or modifying agents for thermoplastic elastomer adhesives, or as components of thermoplastic resin-elastomer adhesives for metal bonding. ESCA yields chemical analysis of organic surfaces in atomic percentage, with the exclusion of hydrogen, which is undetectable by this technique. Under conditions of high humidity and DC voltage, however, silver is reported to undergo electrolytic migration to the surface of the adhesive. Developments in polymerization and adhesive chemistry proceeded in a near parallel fashion.

Be the first to review this item Amazon Best Sellers Rank: Sometimes the adhesive bond is so strong that the failure occurs in one of the adherends away hnadbook the bond.

They also guarantee accurate formulation of components. Aerospace structures, including helicopter rotor blades, require smooth exteriors to minimize drag and to keep temperatures as low as possible. These materials will bond all common metals, glass, ceramics, and thermosetting plastics to each other.

Dextrins are water soluble, white to slightly yellow solids that are optically active. Wood Chemistry, South Africais the author of more than research and technical articles, patents, contract reports and international conference papers as well as 7 books on adhesion and adhesives published in New York, and is the recipient of numerous international prizes for new industrial developments in his fields of specialization.

Cellulose nitrate is tough, develops strength rapidly, is water-resistant, bonds to many surfaces, and discolors in sunlight. Mittal obtained his Ph. Casein glues are used at room temperature and set or hardened by loss of water to the wood substrate and by a degree of chemical conversion afhesive the protein to the more insoluble calcium derivative.

Adhesives Technology Handbook, 2nd Edition

Browse content Table of contents. Smooth surfaces are an inherent advantage of adhesively joined structures and products. The higher homologs, however, generally adhesivee not form bonds as strongly as the methyl form.

Their primary function is to hold structures together and to be capable of resisting bearing high loads.

These include organic materials such as casein, blood, albumin, Adhesives Natural Synthetic Thermoplastic Thermosetting Figure 4.

Chapter 7 is devoted to the design of joints. If the adhesive does not wet the surface of adhesibe substrate completely, the bond strength is certain to be less than maximal. The pressure is then increased to 0. The distinction between structural and nonstructural bonds is not always clear. Film and tape adhesives differ from paste and liquid adhesives in that the former contains a high proportion of high-molecular-weight polymer.

This is done to assure that the dispersion remains liquid when cooled to room temperature so that it can be bottled.

The correction factors have been determined and tabulated. Amazon Advertising Find, attract, and engage customers. Kinloch, Preparing low-energy surfaces for bonding. Neoprene joints may require several weeks of conditioning to yield maximum strength. Fatty polyamides are probably the most technolog used epoxy curing agents. Asphalt emulsions are used to increase solid content, improve water resistance, and lower the cost of laminating adhesives.

PBIs are expensive and are limited to the bonding of high-temperature metals stainless steel, beryllium, and titanium.

They are used mostly in stressed joints and designs with caps, overlaps, and stiffeners. Where temperature variations are encountered in the service of an item containing dissimilar technologyy, adhesives perform another useful function.

Fatigue and impact strengths are excellent. Resistance to oleic acid, oxidizing agents, and strong bases or lime is poor. They are also used in wood bonding and in bonding metal sheets to various substrates; in bonding glass to glass; porcelain; leather; textiles; stoneware, etc. Excess acidity due to poor control of the acid catalyst content often leads to wood damage on exposure to warm humid air.

The cellulose ethers have fair to good resistance to dry heat.
