Denso North America has released a new line of self-priming, spray applied coal tar epoxies and a coal tar epoxy alternative for the long-term corrosion protection of steel and concrete substrates against water, wastewater, seawater, alkaline water, and acidic water corrosion.

These high build two-part epoxies are designed to work in conjunction with cathodic protection and prevent corrosion by coating steel piles, sheet piles, lock gates, reservoirs, non-potable water pipelines, treatment or storage tanks, bridges, and many other aggressive industrial applications.

New Coal Tar Epoxies

The Protal 600 CTE (Coal Tar Epoxy) is a two-part, high build coal tar epoxy that can applied as a single or two-coat system. The epoxy can be applied in up to 26 mils [660.4 microns] of wet film thickness (WFT) in one coat.

Meanwhile, the Protal 600 CTE Low VOC is a two-part, high build coal tar epoxy that has low volatile organic compounds (VOCs) (0.4 lb/gal, 0.05 kg/L). This coating, which can be applied in up to 25 mils (635 microns) WFT in one coat, can be applied as a single or two-coat system.

Both coatings are polyamides with excellent abrasion and chemical resistance, allowing them to exceed many leading exterior standards, according to the company.

Coal Tar Epoxy Replacement

Finally, the Protal 650 CTR is an environmentally friendly non-carcinogenic coal tar epoxy replacement, for use when projects specifications prohibit the use of coal tar epoxies. It can easily be applied by brush or spray methods at a high build of 16 to 26 mils (406.4 to 660.4 microns) in one coat.

The replacement provides strong resistance to water and seawater while offering impact resistance as well, according to the company.
