  • What are Lumiflon resins?

    LUMIFLON was developed and commercialized in 1982 by Asahi Glass as the first solvent-soluble fluoropolymer for coatings that can be cured at room and elevated temperatures. This makes LUMIFLON suitable for use in both field applied and shop applied coatings. Since 1982, fluoropolymer coatings based on LUMIFLON have been produced by many coating manufacturers worldwide. LUMIFLON based coatings maintain gloss and color when applied to buildings, bridges, water towers, aircraft, automobiles, and other structures for well over 20 years. They also protect steel, aluminum, fiberglass, concrete, and other materials of construction from corrosion, sunshine, wind, and rain. The use of LUMIFLON resins can substantially reduce life cycle costs, including maintenance cost, replacement cost, and re-coating costs. LUMIFLON resins are available in conventional solvent grades. Powder coated, water based resins and solid resins allow for the production of low VOC and HAPS free environmentally friendly coatings.

    Polymer Structure of LUMIFLON Resins

    LUMIFLON resins consist of alternating segments of fluoroethylene and vinyl ether, or FEVE. This regularly alternating structure, combined with the chemical stability of the carbon-fluorine bond is responsible for LUMIFLON’s durability, weatherability, and corrosion resistance. The fluorinated segments protect the vinyl ether segments from degradation by UV light and chemicals, while the vinyl ether segments impart solubility, gloss, pigment compatibility, adhesion, and reactivity.

  • Because LUMIFLON-based coatings offer crisp, clean colors and a wide range of gloss, designers and builders choose them to achieve a superior look from day one. And with LUMIFLON’s ability to resist UV degradation, corrosion, and the ill-effects of chemical exposure, projects using LUMIFLON continue looking good for years to come with little or no maintenance required. That means markedly less fading, discoloration or chalking for the life of the coating – which is estimated at up to 60 years! Meanwhile, AGC’s research and development team continues to press LUMIFLON’s aesthetic advantage with new FEVE resin formulations that add even more improvements, like the ability to resist dirt and grime.

  • Corrosion is a major problem that can dramatically add to a project’s life cycle costs, especially for bridges, water towers and other metal structures.

    A LUMIFLON-based coating:

    • Resists degradation due to weathering and exposure to ambient chemicals
    • Over the course of many years, loses little of its thickness
    • Keeps corrosion initiators from getting past the topcoat and degrading the zinc-rich primer underneath
    • Has an estimated coating life of 60 years or more

  • There are those who make buying decisions based on price – and then there are those who are more interested in value. With LUMIFLON, the difference is clear.

    • LUMIFLON-based coatings maintain gloss and color when applied to buildings, bridges, water towers, and other structures for between 20 and 60 years – significantly longer than other coating types.
    • LUMIFLON resins protect steel, aluminum, fiberglass, concrete, and other materials from corrosion, sun, wind, rain and chemical exposure.

    Over time, all that protection also protects your bottom line. Total life cycle costs, factoring in savings on maintenance, re-coating and replacement, are much lower with LUMIFLON. Based on results from numerous projects, it’s estimated that the life cycle cost of LUMIFLON coatings is only 40-80% of that of polyurethane. Price versus value. Over the course of a project’s lifetime, the difference can be monumental.

    Life Cycle Cost Advantages

    Initial applied cost of FEVE-based topcoat:
    • 5-10% higher than standard polyurethane topcoat

     

    FEVE-based topcoat life expectation:
    • 30-60+ years

     

    Expected maintenance of standard polyurethane topcoat in this time frame:
    • 2-3 repainting cycles

     

    Additional costs of repainting:
    • Asset downtime
    • Staging costs
    • Environmental costs
    • Emissions and CO2 from equipment

    Technical Bulletin-Life Cycle Cost Analysis

  • The weatherability, longevity and the ability to formulate low VOC coatings with LUMIFLON resins are all features that contribute to its sustainability.

    Using LUMIFLON FEVE Coatings may qualify for the following LEED v4 credits:

    Materials and Resources Credit Building Life-Cycle Impact Reduction: 

    A requirement of this credit includes demonstrating a reduction in materials use through life-cycle assessment. The life of materials coated in FEVE technology far outlast materials with no coating, or with a lesser quality material.

    Sustainable Sites Credit Rainwater Management:

    Use of emulsion-based FEVE coatings over existing roof coatings improves quality of storm water from roofs by eliminating water contact with the underlying roof surface. FEBE coatings are very stable and do not bond with water molecules.

    Sustainable Sites Credit Heat Island Reduction:

    A FEVE clear coating added to an existing roof coating will help maintain solar reflectivity of the roof, reducing the what island effect. Tests performed in Japan indicate that the use of FEBE resins reduces dirt accumulation on a roof, helping to maintain effectiveness of the reflective roof system. FEVE resins have been formulated in white coatings that have been tested buy the Cool Roofs Rating Council (CRRC) lab for Solar Reflectance Index (SRI). At SRI’s exceeding 100, FEVE based coatings qualify as cool roof coatings.

    Energy and Atmosphere Prerequisite Minimum Energy Performance:

    FEVE coatings on roofs and curtain walls perform at optimal levels after years of exposure to the elements. resulting in less heat transfer through the envelope and reduced cooling loads.
