描述
699N-205 Gray (also referred to as 699-205) is a waterborne 699N-205 Gray ETFE High Build Topcoat from Chemours‘ Teflon industrial coatings portfolio, genuinely manufactured by Chemours and imported as original product. As an authorized distributor and trader, we supply genuine material with full traceability and direct access to official Chemours technical documentation. For more product options and company information, please visit our website at https://szrqchem.com/.
699N-205 Gray is a waterborne ETFE (ethylene tetrafluoroethylene) topcoat specifically engineered for high build / thick film applications. ETFE is a thermoplastic copolymer of ethylene and tetrafluoroethylene. Although not fully fluorinated, ETFE has excellent chemical resistance and is the toughest of the fluoroplastics. This resin is extremely tough, abrasion resistant, and has excellent chemical resistance. ETFE is also an excellent electrical insulator and has good nonstick and low friction properties.
699N-205 is the liquid form of ETFE filled powder 532-6118. This coating is formulated with special blends of fluoroplastics and other high-performance resins to deliver unsurpassed thick film protection for the most demanding industrial applications. The coating is specially formulated to resist sagging in thick films, ensuring uniform coating quality even at high film builds. The gray pigmented finish provides a consistent industrial appearance while delivering superior protection against chemical corrosion and permeation.
699N-205 is FDA compliant for food contact applications per 21CFR when used in combination with a compliant layer and properly cured, making it suitable for food processing equipment, industrial bakeware, and other food‑contact uses. As a waterborne coating, it offers low VOC emissions, making it an environmentally responsible choice for modern industrial facilities.
With regular stock availability, we support both trial orders and large‑volume bulk shipments for heat exchangers, chemical processing equipment, semiconductor equipment, pharmaceutical manufacturing, and other demanding industrial applications.
