Arkema has introduced its Kynar Aquatec CRX latex, a waterborne polymer dispersion for producing highly weatherable waterborne, air-dry paints and coatings based on Kynar PVDF resins with low levels of volatile organic compounds. While many coating properties, including weathering resistance, are obtained from the Kynar resin, other enhancements, such as early hardness, solvent resistance and adhesion, are obtained by modifications to the acrylic component of Kynar Aquatec CRX latex. This innovative new technology is designed for high-performance OEM 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.
Window and door profile manufacturers who are familiar with the extreme longevity and low maintenance of Kynar 500 resin-based coatings on metal substrates are demanding that same level of performance on vinyl and pultruded fiberglass substrates. The advanced Kynar Aquatec CRX latex meets this need as the first aqueous 2K system that achieves AAMA 615 and AAMA 625 performance-based standards with the outstanding weathering and abrasion-resistance properties of Kynar 500 PVDF resin-based coatings.
