The Future of Protective Coatings
MCU-Coatings® delivers a next-generation moisture-cured urethane system that is easy to apply, cures rapidly in any humidity, and delivers exceptional long-term durability.
Our streamlined suite of primers, intermediates, topcoats, and supporting products is engineered to simplify specification, reduce application risk, and improve project outcomes.
Primers ensure superior adhesion, intermediates provide efficient build, and topcoats deliver durable, long-lasting protection. Every product is built on high-quality, stable urethane resins designed for predictable application and proven long-term performance.
Traditional coating systems typically require three coats to achieve long-term durability. MCU-Coatings® achieves the same — or better — protection using a two-coat, thin-film system. Independent testing has verified +25 years to first maintenance in a C5 environment, even when applied to an ST3 surface preparation.
Because our product suite is engineered for broad, multi-purpose performance, most projects can be completed without relying on dozens of specialised, single-use products. This simplifies specification, reduces inventory, and lowers the risk of application errors.
Get good at simplicity. Protect more. Waste less. Finish faster with MCU-Coatings®.
