Anticorrosive applications

Possible combinations of red lead with various binder systems are listed in Table 39 [5.114]. Red lead is still used for heavy-duty anticorrosion applications, especially for surfaces bearing residual traces of rust. In waterborne paints, red lead has no advantages over zinc phosphate [5.149]. 

Polyaniline has been grafted onto the poly(styrenesulfonic acid-co-aminostyrene) backbone using aniline, ammonium persulfate, and hydrochloric acid. The graft copolymer is water soluble and self-doping and can be used in electrical and marine anticorrosive applications. 

Probable applications in various fields like electro chromic displays, electronic devices, modified electrodes, chemical- and bio-sensors etc. [ 133] may be envisaged. Potentially, nanodimensional oxide- (Si02, Mn02 and Zr02) based composites of these polymers have shown promise as optical materials [50]. Conducting polymer-coated low Tg latexes of sub-micron (50-500 nm) dimensions are reported to find use in antistatic and anticorrosion applications [ 113]. In the light of this information it would be of interest to explore the usability of the corresponding MMT-based composites in these directions. 

The author has been involved with the rubber industry for almost forty five years in the non-tyre sector, in production, manufacture and research and development and has aimed to focus throughout the chapters on the most important aspects covering the nature and use of various rubbers in anticorrosive application. 

Conventional vinyl ester resins are increasingly used in anticorrosion applications and in marine applications. They are essentially epoxy resins, but chemically modified to enable them to cure in just the same way, and with virtually the same chemicals and fabrication procedures as polyesters. They have excellent water resistance and chemical resistance, but poor resistance to UV light, although modifications can be made to make them light stable and suitable for use in weatherable gelcoats [13]. 

Methacrylate-based copolymers are used often for anticorrosive applications. Copolymers from N-vinylcarbazole and glycidyl methacrylate have been synthesized using a free radical solution polymerization technique [229].

Another line of approach to the practical application of 1,3-oxazine derivatives was the suggested use of tetrahydro-1,3-oxazine derivatives as detergents for textile industry, as anticorrosion chemicals, and polymers from 2-oxo derivatives as additives to improve the properties of paper and textiles. ... 

A special application of the ether carboxylic acid in metalworking has been described by Schuster [46] a boric acid ester has been produced by condensation of boric acid, alkanolamine, and alkyl ether carboxylic acid, eventually combined with a fatty acid. This condensation product gives less Ca soap precipitation, good anticorrosion effect, better removability of residues, and cleaner apparatus than the condensation product using only fatty acid. 

Often a phosphorus-containing surfactant provides the combination of desired characteristics, e.g., wettability, detergency, and anticorrosiveness. Thus classification by discriminate application is difficult. The following structure only serves the purpose of a better survey. The limits between specific sections are hazy, and as a result the mentioned surfactants encompass more than one characteristic.

The development of conducting polymers is naturally related to hopes of feasible technical applications. Thus, conducting polymers are discussed as active battery electrodes [10], electrochromic displays (BCD) [11], anticorrosives [12], sensors [13], electrocatalysts [14], antistatic materials [15], or light-emitting materials (OLED) [16],... 

Another widespread application for flake zinc pigments is the coating of small articles with complex shapes (e.g., screws, steel springs, bolts, rivets) and for special anticorrosive paints (Section 5.2.11.1).
