Teflon coating a-arms and rear suspension
- Thread starter 2blade
- Start date
I used to have teflon coated wheels on my truck. they were awesome and pretty tough.
Does this mean T-Fal is getting into the sled business???
Can you give us details on the PTFE coating you are talking about?
What is the trade name, brand, etc?
Is is a PTFE impregnated Powder Coat? Paint?
What colors are available?
Who offers this service?
Thanks in advance!!

Teflon® PTFE
Teflon® PTFE coatings have the lowest coefficient of friction and highest temperature resistance of any of the Teflon® coating systems. PTFE-based products can typically withstand temperatures of 550°F on a continuous basis and up to 600°F for brief periods. PTFE coatings are very good electrical insulators and are extremely non-wetting. They are inert to almost all chemicals, but are somewhat porous and thus permeable to water vapor and other gases. The substrate must be able to withstand a cure temperature of at least 750°F to consider PTFE-based coating. Theoretical coverage at 1 mil (25 microns).
Benefits:
One-coat or primer/topcoat system
Excellent non-stick/low friction
Very good chemical/corrosion resistance
Good abrasion resistance
Cure temperature 750°F
Teflon® FEP
FEP-based Teflon® coatings have superb release and are frequently used as mold release coatings. They melt flow to form a non-porous film and are thus more chemically resistant than PTFE coatings. FEP coatings have lower heat resistance than PTFE, but also cure at lower temperatures. FEP coatings are extremely non-wetting and have a very low coefficient of friction. Maximum use temperature is 400°F in an abrasive environment and 450°F in an unabrasive environment.
Benefits:
Primer/topcoat coating system
Excellent non-stick/low friction
Excellent chemical/corrosion resistance
Good abrasion resistance
Cure temperature 650°F
Teflon® PFA
PFA - based coatings combine the high temperature resistance of PTFE coatings with the ability to achieve nonporous, chemical-resistant films like FEP. Films can be built to 40 mil (1000 microns) and ar equite tough and abrasion resistant. Release and coefficient of friction are very good.
Benefits:
Excellent Chemical Resistance
Non Porous Film
Highest dielectric Strength = 3000 volts/mil
Max use Temp 500°F
Cure Temp 750°F
Change build from 40 to 25
Teflon® S
Teflon® S coatings are self priming, one coat products. They are formulated with organic binders to improve adhesion without the use of primers. They typically cure at lower temperatures than pure fluoropolymer dispersions. The fluoropolymer resin stratifies to the surface during the cure cycle, but because of the binder of resins, certain properties of the pure fluoropolymer may be compromised. These include temperature resistance and release.
Benefits:
One-coat/solvent based coating system
Excellent abrasion resistance
Very good non-stick/low friction
Good chemical corrosion resistance
Cure temperature 350-630°F
Specialty Systems
Dupont has created a line of specialty systems that contain a patented combination of PTFE and PFA designed to offer durability and abrasion resistance with excellent release. Specialty Systems are available in a 2 coat, 3 coat Silverstone and 3 coat ceramic reinforced process. These combination coatings comply with FDA regulations in 21.CFR governing components of coatings for direct food contact. Maximum use temperature is 550°F (288C) continuous and 600°F (315C) intermittent.
Benefits:
Long lasting release
Excellent abrasion resistance
Advanced cut resistance
Excellent dialectic resistance
Good chemical / corrosion resistance
Kynar®
The Kynar name is recognizable in the industry, but since Whitford purchased the Kynar 200 Series, it has been renamed Dykor 200. The primary market for this coating is equipment from the chemical processing industry. The 200 Series coatings are used to form a "polymer barrier." Being unaffected by most chemicals and solvents gives this coating unique properties.
Benefits:
High thermal stability
High dielectric strength
Excellent resistance to weathering, UV rays and nuclear radiation
Will not support combustion
Abrasion resistance
Thermal stability
Teflon® coatings may be applied to materials that can withstand the cure temperature of the coating.

Thanks for that..
Is it a Powder coat, an additive, a paint or another type of coating?
Looks like a paint (solvent based) application with a follow up "bake" cycle.. Is this correct?
Do you have a name of an application shop and contact-number/location??
OR... Is there a vendor that sells this (contact info)??
Thanks in advance.
What Colors are available?
I would also worry about application-gun/spray-gun contamination from the PTFE for any subsequent use of that gun with other materials.
The Teflon® S material seems to me to be the only one that could be used on Aluminum parts like rails.... and only at the lower cure temp... otherwise you will loose the temper in the parts in a process called "over aging".... I have seen this on rails that have been powder coated and baked too long or at too high a temp.
