Racine, WI - February 2022 – Modine Coatings, a division of Modine Manufacturing Company (NYSE: MOD), a leader in corrosion resistant coatings technology in the HVAC industry, showcased its innovative GulfCoat™ technology during the AHR Expo in Las Vegas earlier this month.

Known for its ElectroFin® E-Coat and Insitu® Spray Applied Coatings, Modine unveiled GulfCoat™ AM anti-microbial and GulfCoat™ Circuit Shield products during the event.

GulfCoat™ AM is a spray-applied antimicrobial coil coating that utilizes silver ions from the Agion® compound to inhibit the growth of bacteria, molds, fungi and other microbes and deliver long-lasting antimicrobial protection for a wide range of high-performance HVAC/R applications. Agion® is designed to automatically release its antimicrobial components only when conditions for bacteria growth are present. The spray also protects against deterioration caused by mildew, staining and discoloration due to mildew growth and microbial odor development.

GulfCoat™ Circuit Shield corrosion-resistant coating is specifically designed for the protection of circuit boards that are used in outdoor environments. Invented to help protect service equipment circuit boards from early default, the product can protect HVAC equipment, elevator control panels, telecommunications equipment and more. The circuit shield coating was formulated to improve adhesion, moisture resistance, UV protection and corrosion resistance and remain reliable in even the harshest conditions. Modine will also have two other coatings on display at the Expo: GulfClean™ Coatings Warranty Protection and GulfClean™ Contractor Series Coil Coating.

In addition, Modine Coatings also displayed its color modified ElectroFin® AT product, an immersion conversion coating that provides corrosion protection for all-aluminum coils in mild to moderate corrosive environments.

The ElectroFin® AT product is a nano-scale conversion coating, which uniformly covers the entire surface of the coil. The coating is flexible and integral to micro channel and to all aluminum round tube coils and will not flake or lose adhesion. Modine’s Aluminum Treatment provides corrosion protection ranging from C1 to C3 environments including urban and industrial atmospheres, moderate sulfur dioxide pollution and coastal areas with low salinity. Originally a transparent coating, ElectroFin® AT has been modified to include color for visibility.

“At Modine, we are revolutionizing the industry by obsessively innovating new solutions to protect HVAC units against severe corrosion, better satisfying the needs of our customers across the nation,” said Daniel Fisher, director of sales and marketing for Modine Coatings. “The products we displayed at AHR Expo showcased our commitment to providing our customers with the necessary solutions to keep both their own HVAC units and those they service maintained and operating at optimal levels. No names are more synonymous with quality and service than our ElectroFin® and Insitu® products. In addition, we are confident that our exciting new GultCoat™ AM and Circuit Shield products will continue our commitment to high quality standards.”

GulfCoat™ AM

Modine’s GulfCoat™ AM is a powerful antimicrobial after-market coating that is used to protect HVAC systems in hospitals, schools and other settings from mold and mildew caused by fungal growth; deterioration caused by mildew; staining and discoloration due to mildew growth; and the development of microbial odors. To help protect systems, the spray uses silver ions from the Agion® compound to inhibit the growth of bacteria, molds, fungi and other microbes for long-lasting antimicrobial protection. GulfCoat™ AM utilizes UV protection and cost-effective IAQ enhancements to improve indoor air quality and extend the equipment’s life. With GulfCoat™ AM, HVAC systems will continue running at optimal capacity in areas that are more susceptible to organic growth.

GulfCoat™ Circuit Shield

Modine’s GulfCoat™ Circuit Shield provides a micro-thin corrosion-resistant acrylic coating for circuit boards in a range of challenging applications, including outdoor HVAC equipment, elevator control panels, telecommunication equipment, outdoor timers and switches, traffic lighting and rail crossing control panels and off-highway equipment. Created to protect against moisture, pests, dust and chemicals, Circuit Shield keeps HVAC equipment running in harsh environments. Formulated to improve adhesion, moisture resistance and UV protection, GulfCoat™ Circuit Shield coatings can be applied onsite or during manufacturing to protect the performance and reliability of the essential machinery throughout its life cycle.

ElectroFin® AT Immersion-Applied Corrosion Resistant Aluminum Coating

ElectroFin® AT is a nano-scale conversion coating that covers the entire surface of the coil. This flexible coating is integral to MCHE and/or to AI/AI round tube coils. This coating will not flake or lose adhesion because it is applied by immersion, which provides the most uniform and reliable protective coverage you can get. Modine’s Aluminum Treatment provides protection against many C1 to C3 environments while also showing 2400 hours of resistance in urban and coastal areas with low salinity. This corrosion coating is gaining momentum within OEM residential equipment circles due to the relatively low cost and high effectiveness of the protection offered. Originally transparent, ElectroFin® AT has been modified to include color for visibility.
