Significant advances in the synthesis, design and fundamental understanding of these viscoelastic materials have fueled the tremendous growth of the PSA product industry and opened up a variety of often demanding new product applications. There is every reason to believe this growth will continue since these products provide convenience and versatility for both the industrial and consumer market. 

Direct bonding. In many high-volume production applications (i.e., the automotive and appliance industries), elaborate surface preparation of steel ad-herends is undesirable or impossible. Thus, there has been widespread interest in bonding directly to steel coil surfaces that contain various protective oils [55,56,113-116], Debski et al. proposed that epoxy adhesives, particularly those curing at high temperatures, could form suitable bonds to oily steel surfaces by two mechanisms (1) thermodynamic displacement of the oil from the steel surface, and (2) absorption of the oil into the bulk adhesives [55,56]. The relative importance of these two mechanisms depends on the polarity of the oil and the surface area/volume ratio of the adhesive (which can be affected by adherend surface roughness).

We can list the following areas as prime targets essential oil and natural product analysis, chiral analysis (e.g. of fragrances), trace multi-residue analysis, pesticide monitoring, and further petroleum products applications, in fact any separation where simply greater resolution and sensitivity is demanded-which means probably almost... 

For drug substances and drug products, applications for enantiomers and racemates should include a stereochemically specific identity test and/or a stereochemically selective assay. The choice of control tests should be based on the method of manufacture and stability characteristics and, in the case of the finished product, its composition. 

The nominal compositions of commercially pure wrought nickel and the main types of modern corrosion-resistant nickel alloys are given in Table 4.21 some of these supersede earlier variants no longer in production. Applications of nickel alloys are not confined to those where corrosion resistance to aqueous solutions is a prime requirement, and the complete... 

Stress-strain curves at the conditions of product application. If applicable, this would usually indicate the toughness of material by sizing up the area under the curve (Chapter 2). It would also show the proportional limit, yield point, corresponding elongations, and other relevant data. 

Creep data for periods at 100 and 1000 hours (or more, if available) covering stress and temperature conditions closely comparable to those of product application.

However, some of the most widely used phosphonates tend to be poor calcium sulfate inhibitors, and they may adversely affect the corrosion of copper in the boiler, so care in formulation design and product application is very important. 

NOTE Application patents for the use of erythorbates in BW were instituted by Nalco, Betz, and Calgon. The fact that three water treatment patents were issued for essentially the same product application shows the ease of finding alternative application protocols within the industry.

Coatings are used on a large scale in many production applications in optics, electronics, optoelectronics, tools, wear, and erosion and others. In the case of electronics and optoelectronics, practically all CVD applications are in the form of coatings. 

Existing development and production applications in wear, erosion and corrosion protection are shown in Table 17.3.

Plant carotenoids are still extracted at laboratory and industrial scales with solvent mixtnres of ethanol and ethyl acetate, bnt solvent extraction always bears the risk of toxic residnes in the extracts and this limits their use in large production applications in the food and pharmaceutical industries.

Points 1 and 5 refer to the increased importance of functional chemicals [291]. Owing to the wide parameter space determining functionality (not only molecular diversity), this demands much higher flexibility and speed in the preparation of new samples during the research phase. The behavior of complex molecular mixtures needs to be understood. In particular, product application, formulation, and blending skills need to be developed and acquired. In a more remote vision, this demands on-site distributed manufacture of functional chemicals such as paints and similar products. 

Where is the dividing line between bulk and fine chemicals Here again there is no universally accepted definition. Nonetheless, a useful definition of a fine chemical is one with a price of more than 10 US dollars/kg and a volume of less than 10,000 tons per annum. The latter is rather a large volume for most fine chemicals, e.g. most pharmaceutical intermediates are produced in quantities of less than 100 tons per annum. In practice, the type of technology used is probably more dictated by volume than by product application. 

Development is the proof of principle of material design and product applications. 

Utility depends on product applications and proof of superior performance. 

Examples of the utility and need for new, advanced-performance materials are numerous. For example, in turbine engines today, the need is to be able to increase operating temperatures by 100—150 °C. The laws of thermodynamics allow significant fuel efficiency to be gained as the temperature increases. However, the material, particularly for the turbine blades, must be able to handle these increased temperatures. This material need illustrates the connection between product application and material performance. 

One of the unique issues in the development of advanced-performance materials is that they are very product-specific, and their development requires expensive prototype iteration and performance testing. The product development is people- and design-intensive and usually results in a niche market for the material that is, the specific product slate for which the material has been designed and tested. Many of the applications are in high-tech industrial products like aerospace components, so the total volume of material used will be small. Thus, attractive commercialization schemes require that the material have intrinsic value that will justify a high margin, or there must be a product application for which the value can be captured in the end product. 

High development costs and extensive product application work are required for market entry. 

When the users are not the developers, a major mismatch can result between the material design and the end use. Thus, the developer will have extensive product application development to do, which is both expensive and time-consuming. Initial market potentials can be small, and manufacturing capital costs can be high. Thus, the development of new performance materials as the foundation of a materials business does not look very attractive to materials suppliers. Yet, these enabling technologies are very important to the future development of many basic industries. Some models for the successful development of advanced-performance materials are the following ...
