Denso North America recently released a new line of self-priming, spray applied coal tar epoxies and a coal tar epoxy alternative to protect steel and concrete substrates against water, wastewater, seawater, alkaline water, and acidic water corrosion.

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

Protal 600 CTE

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

It is a polyamide with excellent abrasion and chemical resistance exceeding many industry standards for exterior use, according to the company.

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). It can be applied as a single or two-coat system in up to 25 mils (635 microns) in a single coat.

Protal 650 CTR

Finally, the Protal 650 CTR is a non-carcinogenic coal tar epoxy replacement, for use when specifications prohibit using coal tar epoxies.

The Protal 650 CTR can be applied by brush or spray in one coat at a high build of 16 to 26 mils (406.4 to 660.4 microns).

The product provides strong resistance to water and seawater while also offering strong impact resistance as well, according to company officials.
