In the 1970's the offshore industry made a request to the coating industries to develop a coating that could be applied in high humidity conditions. This was due to the numerous pre-mature coatings failures for offshore marine maintenance. We will discuss here one of the most viable new technology developments the moisture cure urethane, more aptly called polyurea and developments over the past 30 years. The most viable result was a single component pure urethane product that goes through a rather complicated production procedure where it is pre-reacted. The final cure is through the exposure to minimal amounts of moisture forming a polyurea. This is quite a different product to the two component polyurethane coatings in many ways. In comparison to two-component urethane, it is a much safer product for the applicator in primarily due to the lack of isocyanate (carcinogenic) free monomer. The polymer technology for this technology is used for production of many common products today including artificial heart valves, tennis shoes, automobile parts and caulking compounds for example. Independent third party testing has proven this to be more effective for corrosion resistance and long term monitoring of projects have demonstrated the MCU's to be more durable and have a longer lifespan, when compared to plural component technology.
