Why is ‘MCU’ so much better than coal tar epoxy or modified epoxy on pilings, locks, gates, penstocks and marine exposures?
Simply put, ‘MCU’ coatings last longer. No other coating in the world can offer 20,000 hours on ASTM salt spray testing and MCU’s coatings can be applied in the high humidity and damp conditions that completely hamper the applications of epoxies. MCU’s coatings are more surface tolerant, weather better, are more resistant to impact, more resistant to undercutting and are very flexible and the best coatings available for resistance to embrittlement. Moisture-cure urethanes, or more correctly polyureas, retain flexibility better than any polyurethane or epoxy.
