Use this table for general guidance only. All Teflon® fluoropolymers have all of these properties. The table listings show which coating systems excel in desired property, but other application requirements such as substrate type, film build, bake and use temperatures, food contact, etc., may necessitate the selection of another choice. However, severe compromises are seldom necessary since a Teflon® coating system offering the desired balance of properties is usually available.
A variety of specific products are available in each of the fluoropolymer categories above. Consult the Product Fact Sheets for individual listings and details.|
Typical properties tested in accordance with ASTM methods are shown on the next pages.
When choosing a protective coating, consider the following important elements:
Substrate
Ability to withstand grit-blasting or etching
Ability to withstand high temperature bake
Service Requirements
Maximum continuous and intermittent operating temperature
Priority of properties needed – nonstick, chemical resistance, mechanical toughness, heat resistance or low friction
Film thickness
Food Contact Some Teflon® industrial coatings are formulated for food contact uses. From time to time, however, regulations in various countries change. Contact a DuPont Sales Office for information regarding conformance of specific coatings to be the appropriate regulations in the countries where your products will be sold and used.
Medical Uses DuPont does not evaluate Teflon® industrial coatings for medical applications involving permanent or temporary implantation and/or internal contact with fluids and tissues in the human body. Except in a few special circumstances, we maintain a strict policy prohibiting such uses. Please consult the DuPont Policy Fact Sheet* for details.
Health and Safety Teflon® industrial coatings have been used safely for 50 years, and it is DuPont policy to maintain this excellent safety record. For specific details please consult the Safe Handling Practices Fact Sheet* amd the Guide to the Safe Handling of Fluoropolymer Resins* booklets published by the Society of Plastics Industry, Inc.
