Corrosion-resistant coatings, for metallic

Some of these polymers are thermally stable, some have high molecular weight (150000), some are soluble in organic solvents, some are fusible, some can be cast into films. These polymers have been suggested as viscosity stabilizers for oil, grease thickners, anti-static agents, and corrosion resistant coating for metals.

It is claimed that the cured materials may be used continuously in air up to 300°C and in oxygen-free environments to 400°C. The materials are of interest as heat- and corrosion-resistant coatings, for example in geothermal wells, high-temperature sodium and lithium batteries and high-temperature polymer- and metal-processing equipment.

Catalysts for the production of fuels and chemicals. Optical coatings for window glass. Electrodes for batteries and fuel cells. Corrosion-resistant coatings for the protection of metals and ceramics. Surface active agents, or surfactants, for use in tertiary oil recovery and the production of polymers, paper, textiles, agricultural chemicals, and cement. 

Coatings permanent flexibility ability to bridge small cracks resistance to weathering, ageing, radiation, ozone and temperature protection of monuments as a weather-resistant coating for building materials rust and corrosion resistance coating on metallic rooves and tank surfaces, etc. 

The elements may be obtained by reduction of sulfides or oxides (e.g. ZnO with C). Zinc and cadmium are used for corrosion-resistant coatings. The metals have melting and boiling points that are lower than for group 2 elements, especially with Hg, which is one of two elements (Br being the other) existing as a liquid at...

The dissolution of material into an aqueous solution and so on, has a merit as well as a demerit to the enviroimient. Consider coated materials for an example. One of the objectives of a surface treatment such as plating is to improve corrosion resistance. In this case, it is preferable that the materials do not dissolve in water. This improvement of corrosion resistance enables the long-term use of materials, and will contribute to the reduction of resources and energy required for materials production. In Japan, JIS (Japanese Industrial Standards) H8502 (1999) regulates the methods of corrosion resistance tests for metallic coatings so as to evaluate the corrosion of a material. This standard includes the ISO 4540 (1980), ISO 4541 (1978) and others. 

Addition of one mole of P,P -dipheny1methy1enediphosphinic acid to tetraisopropyl titanate gives a chelated product, the solutions of which can be used as a primer coat for metals to enhance the adhesion of topcoats, eg, alkyds, polyalkyl acylates, and other polymeric surface coating products, and improve the corrosion resistance of the metal to salt water (102). 

Recently it has been shown that the oxides of the platinum metals can have a higher corrosion resistance than the metals themselves , and have sufficient conductivity to be used as coatings for anodes, e.g. with titanium cores. Anodes with a coating of ruthenium dioxide are being developed for use in mercury cells for the electrolysis of brine to produce chlorine , since they are resistant to attack if in contact with the sodium-mercury amalgam.
