Product Information

Coating powder

NEOFLON

PFA coating powder

NEOFLON PFA coating powder is fine particles of copolymer of tetrafluoroethylene and

perfluoroalkylvinylether.

Since NEOFLON PFA has lower melt viscosity than

POLYFLON

PTFE, it can make a

pinhole-free coating film. It is suitable for anti-corrosion linings.

This film shows the same excellent properties of POLYFLON PTFE film, such as chemical

resistance, heat resistance, non-stick property, low friction and outstanding electric property.

1. Characteristics

1-1 Workability

(1) It can make thick film.

When an appropriate processing condition is selected, thick film can be obtained with
NEOFLON PFA coating powder. The advantages are reduced processing time, and a
superior capability for use in heavy corrosion resistance application.

(2) It has a wide range of sintering conditions.

It can be sintered within the range of 340

(3) Various methods are applicable.

General equipment for powder coating can be applied.

1-2 Characteristics of film

(1) Excellent resistance to stress cracking.

(2) Excellent chemical resistance.

(3) Excellent heat resistance.

(4) Excellent non-stick property.

(5) Excellent electric property, weather resistance, and incombustibility.
