ETFE Powder

Ethylene tetrafluoroethylene (ETFE) is a thermoplastic copolymer derived from the polymerization of ethylene and tetrafluoroethylene monomers. These materials are extremely tough and abrasion-resistant having excellent chemical resistance and continuous operating temperatures up to 150°C (300°F). ETFE is also an excellent electrical insulator and has good nonstick and low-friction properties. The Everflon ETFE JP40 coatings listed above represent a new, improved formulation of ETFE resins. All of the ETFE coatings listed above are now suitable for food contact end uses. Using appropriate product combinations. coating systems are now available for use in a wide variety of applications ranging from thin-film systems (75- 250 µm [3-10 mill) for service involving abrasion resistance or mild chemical service. to thick-film systems (up to 1300 µm 150 mill) for linings where excellent chemical protection is required.

Thick-film Everflon™ ETFE coatings have been improved for application in thicker films per coat and for better sag resistance when approaching the final thickness. The application technique involves a spray-and-bake procedure whereby multiple coats, sprayed and baked individually, are used to achieve the desired final fi lm thickness. The resulting finish is tough, seamless. and without pinholes-perfect for applications in harsh chemical environments. The relative chemical inertness of Everflon™ ETFE also makes it ideal for applications where maintaining product purity is critical.

Available in powder and liquid forms, Everflon™ industrial coatings offer nearly limitless versatility and function for a multitude of industries. Everflon™ industrial coatings are desirable for use across many applications, based on the following properties:

• Nonstick: Few solid substances adhere permanently to a Everflon™ industrial coating. Tacky materials may stick temporarily, but almost all substances release easily.

• Low coefficient of friction: Everflon™ industrial coatings lower the kinetic coefficient of friction to a range of 0.05 and 0.20, depending on the load, sliding speed, and coating.

• Heat resistance: Everflon™ industrial coatings can operate continuously at temperatures up to 260 °C (500 °F) and be used for intermittent service up to 316 °C (600 °F), with adequate ventilation, without affecting other properties.

• Chemical resistance: Because the low porosity of Everflon™ industrial coatings enables greater permeation resistance, chemical environments tend not to affect them. The only chemicals that may have a negative effect are molten alkali metals and highly reactive fluorinating agents.

• Non-wetting: Everflon™ industrial coatings resist water (hydrophobic) and oil (oleophobic). The low surface energy of the coatings creates cohesive forces strong enough to make water bead up and not spread across the coatings’ surfaces.

• Unique electrical properties: Everflon™ industrial coatings have a high dielectric strength, low dissipation factor, and high surface resistivity over a wide range of frequencies. Adding fillers to certain coatings facilitates their use as anti-static coatings.

• Abrasion resistance: Excellent durability and toughness help Everflon™ industrial coatings resist scratches and abrasion. Coatings with added fillers keep scarring to a minimum.

• Food contact compliant: Many Everflon™ industrial coatings comply with regional food contact regulations such as the U.S. Food and Drug Administration (FDA 21CFR).
