From The Powder Coating Show

We're at the Powder Coating Show!

We are exhibiting DuPont Teflon® industrial coating products at the Powder Coating Show. This is the only trade show solely dedicated to the powder coating industry in North America. The Powder Coating Show provides opportunities to meet and interact with leading professionals in the powder coating industry, as well as hear about the latest powder coating innovations and technology.

In addition to exhibiting, our president, Mike Patterson, spoke today at noon about Expanding Your Horizons With Fluoropolymer Coatings.  See more information on his session here.

If you are at the show, please stop by our booth #716.

Properties of Teflon: Chemical Resistance

DuPont Teflon® industrial coatings are highly durable and long lasting performance coatings that have a distinct application process and qualities that offer solutions in a variety of industrial markets.   This series of blogs will highlight one of these inherent properties of Teflon®  coatings and how these properties can solve a variety of problems. 

Chemical Resistance: Chemical environments usually do not affect a DuPont™ Teflon® industrial coating.  The only chemicals known to affect these coatings are molten alkali metals and highly reactive fluorinating agents. Minimal porosity leads to excellent permeation resistance and low chemical absorption. Teflon® coatings’ resistance to chemical action makes the coatings a good choice for the chemical processing and semiconductor industries. PFA and ETFE have the best chemical resistance to many acids, bases, and solvents due to the coatings ability to melt-flow and achieve high film builds.

TruPak Powder Coatings: TruHammer

Through partnering with TCI powder coatings, Intech is now offering more than 300 of the most popular TCI powder coatings in 1, 3, 5, and 10 pound boxes through a program called TruPak.  These products come from TCI's extensive portfolio and are available in a variety of textures and effects that meet the quality demands that you would expect from a powder coating supplier. There are several powder coating products offered through the TruPak program, and this article focuses on the TruHammer line. 

TruHammer hammertone powder coatings are formulated with a base coating that has a unique reaction when exposed to radiant or convection heat, which creates a hammered texture effect. Unlike most hammertones, TruHammer assures the broadest application window, giving the coater the most robust coatings available. TruHammer coatings come in several colors, including Silver Rock, Storm Blue, Dark Pewter, Brown, and Mist Green. Ideal applications include electrical cabinets, indoor furniture, outdoor furniture, wire goods, and lighting products.

Powder Coating Application: Curing

The final step to the powder coating application process is curing. The following is some important information about curing TCI powder coatings:

Different Baking Needs for Different Powders: 
Thermoplastic powders need enough heat to liquefy and smooth out the coating film.
Thermoset powders need enough heat to liquefy the film and enough time at the specified bake temperature to fully develop the coating’s properties.

The Stages of Curing Powder Coatings:
The melt point is when powder particles change from solids to a semi-liquid state.
The flow stage is when the powder is completely liquefied and the film will smooth out.
The cross-linking stage refers to when the heat triggers chemical reactions within the film to change the product’s chemical and physical properties.
The gel stage happens after sufficient crosslinking has occurred and the coating starts to solidify again.
Cure development is the most important stage, when the coating has fully developed all of its final properties.

For more information about powder coating application, read TCI's Troubleshooting Guide

Intech Services and TCI Powder Coatings have partnered to create TruPak, a program that offers over 300 of TCI's most popular powder coatings in 1, 3, 5, and 10 pound boxes. Click here to buy TruPak powder coatings.

Teflon Technical FAQ: Coating peeling off substrate

Every day at Intech we receive requests for technical help with DuPont Teflon® industrial coatings.  If you have a technical question, please feel free to call and speak to one of our technical sales representatives.  Once a month, we post a frequently asked question here on our blog. 

Question: I am having issues with peeling. The Teflon® coating is peeling up right off of my substrate. We grit blasted the part then applied the coating according to the fact sheet. What went wrong with the application or the coating?

Answer: This is called inter-coat adhesion failure. It's when the coating or base coat lifts cleanly off the part and shows the bare metal. In order to prevent this, the part needs to be cleaned properly after grit blast.  In order to ensure adhesion of the coating, most Teflon® coatings require the substrate surface be roughened by grit blasting. Aluminum oxide is the recommended grit blast media. After grit blast, the part should be shot with air to remove contaminants (rust, oil, grease, etc.) from the part and wiped down with a acetone cloth. To assure all organic surface contamination has been removed, it is recommended that the part is pre-baked at (or slightly above) the final cure temperature.
