With the advent of use of high-performance organic coatings on cathodically protected structures such as gas and oil transmission linepipe, the cathodic disbondment properties of a particular coatings system have become important material parameters and are now to be found in the manufacturer s technical data for such systems. However, the standards... 

To study atmospheric corrosion, different types of structural steels were used both in uncoated and coated conditions. Some steels provide excellent corrosion protection against certain atmospheric conditions in uncoated state, but most steels are coated with paints to serve the same purpose. High performance organic coatings were used for barrier protection. 

Potassium ionisation of desorbed species (K IDS) with mass spectrometric detection is an extremely useful tool for the characterisation of high performance organic coatings. K IDS uses a commercial rapid heating probe to desorb intact molecules which are then ionised by potassium cation attachment. Based upon the molecular ions, which appear as [M]K, coatings components can be qualitatively and quantitatively analysed. In this work K IDS was selected as a method of soft ionisation, (i.e., producing molecular ions) because of its simplicity, wide applicability, low cost and compatibility with the quadrupole mass spectrometer. Simonsick [76] reports the application of K IDS to polymer additives (UV stabilisers and antioxidants), catalysts (organotin), reactive diluents (vernonia oil and aliphatic epoxides) and polyurethane precursors (polyesters and isocyanates). Tikuisis and co-workers [77] also discussed this technique. 

Paints, coatings, and high-performance organic coatings were developed to protect equipment from environmental damage. Of prime importance in the development of protective coatings was the petroleum industry.

Paint stripping is the process of removing an organic coating from a workpiece. The stripping of such coatings is usually performed with caustic, acid, solvent, or molten salt.

Ref. 102) illustrates the difference in selectivity ascribed by three different ligands for the separation of four cytochrome C derivatives (chicken, tuna, horse, bovine). The improved chromatographic performance of etched and subsequently derivatized capillaries was ascribed to the larger number of bonding sites of the organic coating to the activated surface, which effectively block the access to the silanol groups. 

Rare earths are used in the paints and pigments industry (i) as coating materials for pigments to enhance their durability and performance characteristics, (ii) in the manufacture of ceramic pigments and (iii) in the manufacture of driers for organic coatings.
