In primer formulations for adhesive bonding of metals, the coupling agents that are most frequently used are those based on epoxy and amine functionalities. Aqueous solutions of aminosilanes have been successfully used for obtaining stable adhesive bonds between epoxy and steel [10] and epoxy and titanium [11,12], while epoxy functional silanes are preferable for applications involving aluminum substrates [13,14], A simple solution of % epoxy functional silane in water is currently used for field repairs of military aircraft [15] where phosphoric acid anodization would be extremely difficult to carry out, and performance is deemed quite acceptable.

The primary challenge facing adhesive bonding of metals is to obtain sufficient durability of a bonded structure. Initial bond strength in metal-polymer adhesive joints is almost invariably excellent. Challenging the application of adhesives in polymer-polymer joining, however, is the problem of obtaining a joint that is... [Pg.459]

The literature of metal-support interactions includes httle about the possible chemical bonding of metal clusters or particles to supports. Supported molecular metal clusters with carbonyl ligands removed have afforded opportunities to understand the metal-support interface in some detail, and the results provide insights into the bonding of clusters to supports that appear to be generalizable beyond the small clusters to the larger particles of conventional supported metal catalysts [6].

The participation of the 2p band in the bonding of metallic beryllium explains the greater cohesiveness (bond strength) of the metal when compared to that of lithium, and also why the enthalpies of atomization and the melting temperatures of the two metals are different, as shown by the data in Table 7.2.

The CBI process is an endothermic, physical-chemical bonding of metal ions to alumina-silicate crystals in a high temperature environment. The process is accomplished in two stages proportioning and mixing of the additive material with the metal sludge and thermal processing. [Pg.291]

The chemistry of the dithioformate anion was not explored until recently. A number of studies have appeared in the literature in which the formation of dithioformate complexes by the insertion of CS2 into the M- H bond of metal... [Pg.304]

One framework for discussing the bonding of metal complexes with diatomic ligands is to partition the complex conceptually into the units Mm+ and YJ". The values for m and n are determined by comparing the physical properties of the complex (Y—Y distance, v(Y—Y) (band position and intensity), electronic spectra, XP spectra, magnetic properties) with those of the isolated Y2" species.

The generally accepted valence bond and molecular orbital (MO) approach to the bonding of metal isocyanides has been well described in Treichel s review (6), and has been used to rationalize (i) variations in IR stretching frequencies between bonded and nonbonded isocyanides, and (ii) the better Tt-acceptor qualities of aryl versus alkyl isocyanide groups (53,54). In valence bond theory the canonical forms involved in metal isocyanide bonds are... [Pg.213]

Formally, metal or p-block carbamates can be obtained also by insertion of the heterocumulene in the M-N bond of metal- or p-block-amides [4, 5]. [Pg.121]

The structure and bonding of metal silylene complexes varied from those of their carbon analogs. While Fischer-type metal carbene complexes without solvent adducts have been extensively characterized,48 most metal silylenoid complexes contain a bound solvent molecule or counterion on the silicon atom. The bond energy for donor silicon complex 22 was determined to be between 15 and 20kcal/mol 49,50... [Pg.186]
