Fluoropolymer ETFE Powders

Get to know ETFE Coating Powder JP40

Everflon™ 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 lowfriction properties.

Techyours™ high-build JP40 ETFE coating represents a new, improved formulation of ETFE resin. 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 mil]) for service involving abrasion resistance or mild chemical service, to thick-film systems (up to 2000 μm [80 mil]) for linings where excellent chemical protection is required. Thick-film ETFE coatings have been improved for application in thicker films per coat. The application technique involves a spray-and-bake procedure whereby multiple coats, sprayed and baked individually, are used to achieve the desired final film thickness. The resulting finish is tough, seamless, and without pinholes—perfect for applications in harsh chemical environments. The relative chemical inertness of ETFE also makes it ideal for applications where maintaining product purity is critical.

Precaution

Equipment used to process at melt temperatures should be provided with local exhaust ventilation (LEV) to completely remove all fumes and vapors from the processing area. In addition, care should be exercised to avoid the contamination of cigarettes and other forms of smoking tobacco when using fluoroplastic resins. Before processing any fluoroplastics, read the Material Safety Data Sheet.

Handing & Package

Powders should be stored in closed plastic bags.

Powders may form lumps under prolonged storage; sieving through a coarse screen will restore the powder.

Powders should be usable for an indefinite period of time without caking or deteriorating if stored at optimal storage conditions: 18°C-27°C (65°F-80°F). Maximum storage temperature 40°C (105°F).

Transport conditions:5°C-40°C (40°F-105°F). For safe storage conditions, pls. refer to safety data sheet.
