Further Data & Life Cycle Costs

The world’s first solvent soluble fluoropolymer for coating was developed 37 years ago by Asahi Glass, and the same chemistry remains at the forefront of protective coating technology today due to the extremely durable nature of fluoropolymer coatings. Chemically a fluoropolymer coating is a fluoroethylene-vinyl ether alternating copolymer.

Lumiflon, manufactured by Asahi Glass, is a coating resin, which when formulated into a conventional coating product exhibits very high levels of uV resistance and provides excellent durability when used as the topcoat in a corrosion resistant coating system. Our highest quality fluoropolymer, Vitreflon 700, is based on Lumiflon resin.

This amorphous resin can be cured by cross linking sites and creates tough coating films from room temperature to 250c. the alternating copolymer structure gives excellent durability and chemical resistance, making fluoropolymer the coating of choice for a wide range of applications.

The energy of the alternative main chain bond between fluoroethylene and vinyl ether is higher than the maximum uV energy of sunlight, and so in principal, it does not degrade. in contrast, other coatings such as polyurethane break down and deteriorate due to their low bond energy.

The high weatherability of Vitreflon not only leads to long lasting and beautiful coatings but also dramatically reduces the life cycle cost of the coating due to a decrease in repainting when compared to other conventional coating systems. Simultaneously, the level of VOC’s released decreases thus conserving resources. This graph shows the cost savings for up to 30 years and beyond by utilising a Fluoropolymer coating system.
