Guaranteed Protection
Moisture cured urethanes have been around for years as they were invented in the 1940’s. What is fascinating is why the inventor chose to develop this technology when he started to develop his protective coatings.
The answers are many and varied:
- Urethanes have really good flexibility, chemical resistance, durability and heat resistance.
- Moisture cure polymers are single component, so do not require any mixing, which makes them really easy to use. They are also no limited by high relative humidity, like all other polymer coatings.
- The moisture curing technology cures quickly and is not temperature dependant, and because moisture is plentiful and always available, the polymer cures fully and is therefore stable. What this means is that they do not react with contaminants and they are less affected by ultra-violet (UV) rays.
- The curing reaction uses up any micro-moisture on the substrate, thereby eliminating the cause of any potential secondary corrosion reactions under the coating surface that invariably results in a loss of adhesion.
After commercializing his new technology in the 1980’s and 1990’s what very few people realised was that the inventor went back into the laboratory after he sold his business to upgrade and improve his formulations. As a result MCU-Coatings now has a 2-coat, thin film technology that, in independent testing, has achieved +25 years to first maintenance in a C5 environment using a ST3 surface preparation.
The use of a high-quality urethane base resins that are stable and have excellent performance fundamentals also means that MCU-Coatings do not need an extensive range of specialist coatings – like most other protective coating manufacturers. The primers are designed to adhere, the intermediate coatings are designed for high build, and together with the limited range of top coats the MCU-Coatings product suite can be applied almost anywhere and addresses over 90% of all protective coatings challenges.
MCU ZINC
Single component, moisture cured polyurea coating. MCU-ZINC is a high performance pure zinc rich primer for atmospheric exposure, splash zones, and areas with permanent condensation where the longest possible life is required. It is suitable for maintenance and new construction and has excellent adhesion on St3 prepared surfaces. MCU-ZINC is also the perfect substitute for galvanization. MCU-ZINC is different to most zinc rich coatings as it does not crack when higher DFT’s are applied and does not blister on surfaces that have a low profile.
- Temperature:
-20 °C to 75 °C (-4 °F to 167 °F)
This temperature range should be achieved for ambient, sur- face and material temperature. Substrate must be visibly dry. - Relative Humidity:
6% to 99%*
MCU-Quickcure is advised when relatives humidities are be- low 40% - Coating Accelerator:
MCU-Quickcure. See MCU-Quickcure Product Data for information. - Storage
Store off the ground in a dry, protected area in temperature between -5 ºC to 35 °C (23 ºF to 95 °F). Containers must be kept sealed when not in use. Use a solvent float to reseal partial containers. - Safety precautions

MCU MIOZINC
Single component, moisture cured polyurea primer, combining Zinc and Micaceous Iron Oxide (MIO). MCU-MIOZINC a true universal primer that adheres tenaciously to a wide range of substrates. This primer protects steel in high humidity climates, splash zones, and areas with permanent condensation. The properties of the resin, high quality zinc and lamellar MIO, makes MCU-MIOZINC the perfect primer as it provides both barrier and galvanic protection simultaneously. In ad- dition, MCU-MIOZINC has superior abrasion & impact resistance with long term flexibility. MCU-MIOZINC is more surface tolerant than any epoxy mastic coating and it outperforms inorganic zinc primers. It can be applied as a universal primer for use with conventional epoxy, PU and alkyd coatings. It is excellent as a spot primer and for overcoating and overlapping on existing coatings. It is different to other zinc rich coatings as it does not crack with high DFT’s or blister when applied on surfaces that have a low profile.
