Mallik, Mechanical and Anticorrosive Properties of Non Toxic
Coal-Tar Epoxy Alternative Coating, Prog.
* Availability of new technology--new solvent-free, fast-cure, ultra-high solids epoxy coatings are available that protect against corrosion and replace coatings that have been used in the past, such as
coal-tar epoxy or asphalt coatings impregnated with asbestos fiber or other reinforcements.
Early products, alkyds or
coal-tar epoxy resin coatings, were costly, often required several layers, adhered inconsistently, and were subject to pitting and corrosive gas penetration.
This is a dramatic improvement over cure times of conventional
coal-tar epoxy. The product provides a tough, flexible membrane for concrete tanks--where hairline cracks can be easily bridged.
In many cases they are replacing the black coal-tar epoxy coatings, offering many advantages, both aesthetical and functionally.
Coal-tar epoxy. When used in wastewater treatment plants, coal-tar epoxy coatings are almost always used to combat submerged conditions.
