Features of Techyours™ FEP JP46 coating powder

Everflon™ fluoropolymer coated film exhibits outstanding weatherability, heat resistance, and non-adhesive property. This is widely used in various industries and applications by taking advantage of these properties.In particular, It has great potential for release applications. Techyours™ FEP coated film shows the following characteristics.
Release properties	Techyours™ FEP coated film indicates remarkable non-adhesive property. It is suitable for the application requiring releasefrom other materials.
Chemical resistance	Everflon™ fluoropolymers consist of -CF2- which is one of the strongest single bonds. They demonstrate noticeableresistance against many chemicals like solvents, acids, and alkalis. Especially, FEP can be used for a long time,because it keeps chemical resistance even under high temperature range.
Heat resistance	Techyours™ FEP shows excellent heat resistance, displaying stable release property in the high temperature range exceeding 200°C.
Processability	FEP has lower melting point compared to other perfluoro polymers. FEP powder can make film by being sinteredabout 300°C, which is lower than PFA powder.

Data List

Typical Property Data for Everflon™ FEP JP46 Industrial Coating Powder and films

---

	Coating Preparation	Homogenize powder before opening bag
	Screen	60 mesh (approx. 250 μm) stainless steel or nylon. Insufficient screening can result in application defects.
	Application	Use fluidized bed with or without vibration system (depends on powder quantity and particle size of the powder). On flat and/or conductive parts high voltage and higher amperage can be used. On insulated and complex parts amperage should be lowered. In some situations a fixed voltage may be more effective than using an automatic current control setting. The gun settings depend on the gun type and complexity of the part. Recommended general settings:  • Product supply: 30%-50%  • Air carrier: 3.0 Nm³/h  • Fluidization bed: 0.3 Nm³/h  • Electrode fluidization: flat jet 0.2 Nm³/h  • Amperage: 10 μA  • Voltage: 60 KV
	Recommended Dry Film Thickness	25-60 μm (1.0-2.4 mil) per coat
	Drying (metal temp.)	Powders can be applied dry on wet. Full coating system should be dried before final cure.
	Curing (metal temp.)	10-15 minutes at 360-370°C . Bake temperature of the first coat is important for adhesion to the primer.
	Multiple coats	20-30 min. at 330-345°C.
	Additional long bake	90 minutes at 330-345°C (625-655°F) will improve coating properties such as inter-coat adhesion,smoothness, permeation resistance and abrasion resistance.

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.
