High-performance water tank coatings can extend the service life of the tanks while reducing the frequency of maintenance and recoating. LUMIFLON® FEVE resins provide the long-term weatherability, durability and aesthetic performance needed for demanding water tank applications.
How Do Water Tank Coatings Protect Tanks?
Water tank coatings protect exterior surfaces against UV radiation, moisture, temperature changes and other environmental conditions that can contribute to fading, chalking, coating deterioration and corrosion.
A typical exterior water tank coating system can include a primer, intermediate coat and finish coat, with each layer serving a different function. The primer and intermediate layers provide corrosion protection and adhesion, while the topcoat provides a durable barrier against weathering and UV exposure. The topcoat also plays an important role in maintaining the tank’s color, gloss and overall appearance.
Why Use FEVE Resins in Water Tank Coatings?
FEVE resins are used in high-performance fluoropolymer topcoats because of their exceptional resistance to UV radiation and weathering. FEVE resins help water tank coatings retain color and gloss for extended periods while resisting fading and chalking.
This long-term performance can extend repainting cycles and reduce maintenance requirements—an important life-cycle advantage for elevated water tanks, where surface preparation and recoating require specialized equipment and significant labor.
Design Flexibility for Water Tank Coatings
Water tank coatings can provide long-term protection while transforming highly visible tanks into distinctive community landmarks. LUMIFLON FEVE resins are available for coatings in virtually any color, giving designers flexibility to incorporate colors, graphics and other visual elements while maintaining long-term color and gloss.
FEVE-based coatings also offer application flexibility and can be applied by brush, roller or spray equipment.
How Long Do Water Tank Coatings Last?
Water tank coatings can last 15 to 20 years or more, depending on the coating system, surface preparation, environmental exposure and maintenance. High-performance exterior fluoropolymer coatings can provide even longer service life. FEVE-based coating systems have demonstrated performance exceeding 20 years and can last two to three times longer than traditional polyurethane topcoats.
LUMIFLON FEVE resins are designed for long-term resistance to UV radiation and weathering, helping water tank coatings retain color and gloss for decades. Longer coating life can extend repainting cycles, reduce maintenance and tank downtime, and lower life-cycle costs. Because repainting elevated water tanks also requires significant labor, access equipment and surface preparation, reducing the number of recoating cycles can provide both economic and environmental benefits.
