Specifying Teflon® Industrial Coatings

The high technology performance of DuPont™ Teflon® industrial coatings makes them the natural choice in many industries. DuPont offers the design engineer a range of Teflon® industrial coatings to ensure the ideal combination of properties for the specific application.

How to Evaluate and Specify

Use the following table for general guidance only. All Teflon® fluoropolymers have all of these properties. The table shows which coating systems excel in the desired property, but other application requirements (substrate type, film build, bake and use temperatures, food contact, etc.) may necessitate another choice. However, severe compromises are seldom necessary because a Teflon® coating system with the desired properties is usually available. 

General Product Selection Guide

Required Property  Good  Better  Best 
Chemical Resistance Teflon® S ETFE or FEP  PFA 
Corrosion Resistance FEP Teflon® S Teflon® S over Phosphate Pre-Treatment
Abrasion Resistance PTFE or FEP

Teflon® S

Heat Resistance Teflon® S FEP PTFE or PFA
Nonstick Teflon® S PFA PTFE or FEP

A variety of specific products are available in each of the fluoropolymer categories above. Refer to the Product Guide and Market Guide for individual listings and details.

Test results from ASTM methods are available for typical properties of Teflon® coating systems.
