Product Description

ETFE

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 (302 °F).

ETFE is also an excellent electrical insulator and has good nonstick and low-friction properties. The high-build 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.

Precations

When dealing with ETFE powder for deep processing, operators must wear protective cloth and mask to avoid potential safety hazards, such as inhalation of dust and toxic gas, or hurt by high temperature. No open flame and smoking in workplace. Exhaust devices should be installed.

Packing & Delivery

The product should be stored in cool ventilated place and away from fire source and heat source. It should also be prevented against moisture and sunshine, kept in upright position and handled with great care.

Once opened, unused product should be repacked to avoid any dust or contamination.
