Bruce Nesbitt
"The endless possibilities of product improvement using Teflon® coating excites me"

Bruce Nesbitt is a leader in the industrial coating field.  His experiences over the years help to give perspective on the coating industry and how it has grown and evolved. In an effort to highlight some enduring coaters in the industry, we are presenting a series of interviews conducted with these highly regarded professionals. Our first Pioneer Series interview spotlight is on Bruce Nesbitt, of Orion Industries.  Please read on to learn about Bruce's story in the coating industry. 
 
Q:  When was your company founded?
A:  It was in 1964, in my parents’ basement.

QWho founded the company and why?
A:  I did.  While I was in the hospital recovering from a broken ankle, a friend brought me a magazine that had an article about LeMans racecars. The article discussed how Porsche used a special coating on its engine parts, helping to win the 24-hour LeMans race. Intrigued by what I read I sent away for some samples of the special coating, Molykote, and learned how to spray it on racecar parts.  That was the “primordial goo of Orion.”   I used my mother’s oven in the basement to cure the coating, and although those initial coatings did not involve Teflon®, I began my relationship with DuPont™ Teflon® shortly thereafter in 1966.

Q:  What was the first significant piece of equipment you purchased?
AAn air compressor and an electric oven. Both got worn out.

Q:  How would you describe the changes in the company now from when it was first started?
AFar more documentation now.  NO more collegial transfer of tribal knowledge.  We now document everything and bar code all labor and materials.  However, never have I found a way to lose money on a job and prosper, so we avoid losing jobs, or as the late Pedro Diaz of Boyd Coatings so eloquently said years ago, “Avoid dog customers.”

QWhat would you consider significant milestones in your company?
AMoving from the sixth floor of a building to a ground floor location in 1969.  In addition to a larger working space, I also made changes to expand the business.  I purchased two DuPont™ Teflon® LIA businesses, Fluorocarbon Company and Ekco Industrial Coatings. Ironically, Ekco had offered me a job in 1969 and by 1982 I was buying them.  In addition to these events, several staff members have added to the company’s growth, too numerous to mention.  This is a really unusual industry, so creative and clever staff have made all difference.

QHow has the coating industry itself changed over time?
AWow, much more regulation, especially government regulations. Heightened government regulations have made for fewer marginal coaters but have also increased overseas competition (especially for large housewares jobs).  The industry is more efficient, with tighter controls, allowing for more automation and electrostatics. 

QWhen did you get your LIA license from DuPont?
A: 1973 or so.

QHow has being an LIA affected your company?
AThe LIA status initially provided plenty of leads and assistance from the DuPont sales force.  Today, the LIA offers more technical assistance from DuPont when needed.  The LIA network is really much smaller but with many more good firms. 

QWhat is your favorite DuPont coating? 
A958G-303, 420G-104, and the 851 acid primer series, which we use on a consistent basis

QWhat excites you about the future of the coating industry?
AThe endless possibilities of product improvement using Teflon® coatings excites me.  I also look forward to the next phone call or e-mail with a very unique question about “how will Teflon® coating help my product do this or that.” After 50 years, I still get amped up over the new and next opportunity.  I meet the brightest folks imaginable with imagination and that’s great!

High Temperature Walk-In Ovens: Efficient and Consistent

Intech is proud to represent Precision Quincy Ovens, an industry leading manufacturer of many types of industrial ovens. For over 60 years, Precision Quincy Ovens have been used in industry across the globe.  Precision Quincy can create an industrial oven to fit any need you may have, from large conveyor ovens to small tabletop ovens, and everything in between. 

Precision Quincy ovens are constructed with welded steel and use quality components throughout.  All ovens are assembled, wired, and tested at maximum temperature prior to shipment and meet or exceed NFPA-86, NFPA-70, OSHA & UL requirements.  This article focuses on the High Temperature oven line, which is a multi-use oven made for process temperatures to 1250°F. 

High Temperature Walk-In Ovens are built by Precision Quincy’s proprietary “Can” Construction, meaning the oven’s interior walls are made from seamless steel plate. The seamless interior is superior to normal tongue and groove construction, which could buckle at higher heat.  Buckling allows heat to escape the oven resulting in higher energy costs, less efficiency, and inconsistent product quality.   High Temperature Walk-In Ovens are not standard ovens and therefore require a slightly longer quote time. 



  • Maximum temperatures: 1000° F / 1250° F
  • Suited for most industrial processes like aging, annealing, curing, dehydrating, drying, heat setting, heat shrinking, pre-heating, stress-relieving, and testing
  • Insulated floor 3” or 6”
  • Available in any voltage and with gas or electric heat
  • Available in eight standard sizes or can be customized to meet your specific needs
  • Air Flow:  Horizontal / Vertical

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.

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.

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.

Powder Coating Application: Overcoming the Faraday Cage Effect

The "Faraday cage effect" occurs when the inner recesses and corners of a charged substrate do not have a charge, and the charged powder particles create resistance, making it difficult to coat these areas. There are ways to overcome the Faraday cage effect and better coat inner corners and odd part geometries.


Overcoming the obstacles of the electrostatic process:
  • Blast powder into recesses
  • Increase the powder flow rate
  • Maximize the gun to part distance
  • Use slotted tip to concentrate the spray

These methods can use excess powder, have higher film thicknesses than desired, and could result in an uneven film build.


Using the electrostatic process:
  • Finesse the powder into recesses
  • Decrease powder gun flow rates
  • Reduce gun voltage to 40-60 Kv
  • Maintain gun to part distance of about 8-10 inches
  • Use slotted tip to concentrate spray
  • Approach recess at an obtuse angle

These methods could result in a slower application time. 


Spraying in the Faraday Cage: spraying at the recesses of a part at an obtuse angle can help to apply the coating properly.
  • Reduces air turbulence
  • Allows deeper penetration
  • Minimizes early back ionization
  • Utilizes more lines of force

For more information about how to overcome the Faraday cage effect, read TCI's Troubleshooting Guide.
