Arkema, a provider of advanced chemical technologies for high-performance protective coatings, has announced that its Kynar Aquatec CRX latex surpassed the stringent requirements of the AAMA 2605 performance standard, which included G85 corrosion testing for architectural metal applications and ISO 20340:2009 testing requirements for marine structures.
Kynar Aquatec CRX latex is a waterborne polymer dispersion for formulating highly durable waterborne, air-dry paints and coatings with VOC levels below 100 grams per liter. This innovative technology is designed for high-performance applications where outstanding weather resistance is required (particularly color fade and chalk resistance), along with a high level of scratch resistance and resistance to organic solvents.
American Architectural Manufacturers Association (AAMA) standards help architects, contractors and building owners specify coatings that provide a superior level of performance in exterior weatherability and general appearance over many years. AAMA 2605—the highest standard for coatings on aluminum extrusions and panels—requires rigorous performance evaluations, including new ASTM G85 corrosion testing, to validate a coating’s outstanding resistance to humidity, color change, chalk, gloss loss and chemicals. By surpassing the rigorous testing requirements to meet the ISO 20340:2009 standard, Kynar Aquatec CRX-based coatings demonstrate the ultra-durable performance necessary to protect offshore and related marine structures from the severe corrosion stresses to which they are exposed.
“Achieving long-term coating service life is imperative for exterior architectural products and marine structures,” says James Feorino, global market manager for Arkema’s Fluoropolymers Division. “With multifunctional Kynar Aquatec CRX latex—the first aqueous 2K system to achieve AAMA 615 and AAMA 625 performance for fiberglass and vinyl substrates—customers are assured of the outstanding weathering and abrasion-resistance properties of Kynar 500 PVDF resin-based coatings for metal applications in a completely waterborne presentation.”
