MCU
(Moisture Cured
Urethanes)
At Royalton, our Moisture Cured Urethane (MCU) coatings provide cutting-edge protection through a unique single-component moisture-cured polyurea formula. Designed as a thin-film coating, MCU offers superior physical and chemical protection while maintaining high flexibility and excellent adhesion, even when the substrate preparation is not ideal. This makes MCU a versatile choice for a wide range of industrial and marine environments where reliable performance is crucial.
One of MCU’s most significant advantages is its ability to adhere strongly to substrates like steel, concrete, and other industrial materials, even when surface preparation may be less than perfect. In fact, MCU products can be applied onto existing conventional two-component epoxy coatings, offering additional flexibility for projects where surfaces are already protected with epoxy-based systems. This feature makes MCU an efficient and cost-effective solution for extending the life of existing coatings while enhancing overall protection.
The result is a long-lasting, durable bond that provides robust protection from corrosion, chemicals, and physical wear, without requiring extensive preparation work beforehand.
In addition to its strength, MCU delivers outstanding flexibility, allowing the coating to move with the substrate, resisting cracking or peeling, even in challenging conditions. This combination of flexibility and durability makes MCU an excellent choice for surfaces that are exposed to frequent movement, thermal expansion, or mechanical stress.
Fast Recoating, Efficient Project Completion
One of the key features of MCU is its fast recoat time. Under standard conditions, MCU can be recoated after just 4 hours, which allows for the rapid application of multiple layers. With this fast recoating capability, a full three-coat system can be applied within a single working day, significantly reducing project timelines. This efficiency is particularly beneficial in industries where downtime needs to be minimized, or where weather conditions might limit the time available for application.
For even faster results, MCU-Quickcure is available as an additive, enabling the coating to be ready for recoating within 45 minutes, allowing for even more accelerated application schedules. This makes MCU ideal for high-paced projects where speed is essential without compromising the quality and durability of the final protective system.

MCU-Zinc
Indefinite Recoatability
Window
A standout in the MCU range is the MCU-Zinc coating, a single-component zinc-rich primer. One of its most unique properties is its indefinite recoatability window. MCU-Zinc can be applied onto a freshly sandblasted surface, and the next layer—whether an intermediate or top coat—can be applied months, or even up to a year later. This allows for flexible project timelines and ensures protection even in cases of prolonged intervals between application stages. MCU-Zinc provides excellent corrosion resistance, particularly for metal surfaces exposed to harsh environmental conditions.
Reliable Performance in High Humidity and All Weather Conditions
Unlike many traditional coatings that are limited by weather conditions, MCU performs exceptionally well in environments with high moisture or humidity. As a moisture-cured coating, it can be applied in up to 99% relative humidity without concerns about dew point restrictions. This means MCU can be applied continuously, even in wet or humid conditions, making it an excellent choice for regions where the weather is unpredictable or consistently damp.
Whether in coastal environments, rainy climates, or indoor spaces with poor ventilation, MCU ensures that your surfaces are protected no matter the conditions. This ability to cure and adhere in such a broad range of climates makes MCU ideal for marine applications, as well as industrial settings where humidity is a constant challenge.
Versatile Applications Across Industries
MCU’s flexibility, fast recoating capability, and weather resistance make it suitable for a wide range of industrial, marine, and construction projects. Its superior adhesion and protection make it perfect for coating metal structures exposed to harsh chemicals, concrete surfaces in moisture-prone environments, and equipment in marine and offshore environments.Unlike many traditional coatings that are limited by weather conditions, MCU performs exceptionally well in environments with high moisture or humidity.
