描述
532-6419 Black is an ETFE powder topcoat / midcoat 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/.
532-6419 Black is an ETFE (ethylene tetrafluoroethylene) powder coating 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.
532-6419 is a special filled grade with extremely high resistance against water vapor permeation. Even when applied at only 350 µm thickness, the coating showed no blistering, bubbling, or delamination after one year of exposure. The coating sintered film is very dense and nonporous, providing outstanding chemical corrosion resistance. The black pigmented finish provides a consistent industrial appearance while delivering superior protection against chemical permeation.
532-6419 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 powder coating, 532-6419 contains zero VOCs, offering significant environmental and worker safety advantages.
With regular stock availability, we support both trial orders and large‑volume bulk shipments for chemical processing, heat exchangers, semiconductor equipment, pharmaceutical manufacturing, and other demanding industrial applications.
