Dry Film Coatings

Dry film coatings immensely enhance the ability to differentiate between similar parts or to verify existence of a part that would be hard to distinguish either by a person or automated visual equipment.

Dip Spin Coatings

Dip-Spin coating is a procedure used to deposit uniform thin films to flat substrates. Usually a small amount of coating material is applied on the center of the substrate, which is either spinning at low speed or not spinning at all.

Color Identity

Dry film lubricants are often used as a base for applying color coding to parts for identity. This immensely enhances the ability to differentiate between similar parts or to verify existence of a part where otherwise hard to distinguish.

Useful Information

The coatings we use are the highest quality. Our Polytetrafluoroethylene (PTFE) and color pigments are sized less than 5 mircrons to allow use where other systems cause problems with pumps and filters.

Our goal is to provide a cost competitive service with on time delivery with a high standard of workmanship that gives our customers a competitive edge in their markets.

What Dry Film Coatings Can Do

Like other dry film coatings, a key advantage of Polytetrafluoroethylene(PTFE) coatings is that they remain clean throughout their service life. During the manufacturing and assembly process, they eliminate problems associated with handling, conveying, and assembling parts coated with oils, greases, or silicones. Perhaps more importantly, the solid, dry film resists contamination from an accumulation of dirt and debris. This clean, lubricated surface often helps extend product life and makes service and repair efforts more manageable.

The primary benefit of applying a dry film coating is lubricity. Depending on the material selected, the coefficient of friction ranges from 0.05 to 0.20. Applied as a primary or secondary lubricant, this low coefficient of friction is beneficial in a number of ways. As you’d expect, it cuts wear and stops squeals and rattles. But it also supplies interim lubrication during break-in, reduces binding during assembly, and provides release for tooling or parts in a manufacturing line. PTFE coatings also provide corrosion, abrasion, and chemical resistance.

An often-overlooked benefit of dry film coatings is that they can be formulated to produce a variety of colors. A black rubber O-ring can be transformed to royal blue, and a lug nut can be a highly visible safety yellow. These colored coatings offer quick identification of parts that are similar in size, compound, or alloy. Colored parts also help ensure proper insertion and placement and give a visual appeal for decorative purposes.

The History of Teflon™

Did you know Teflon™ was invented by mistake?
The man who invented it was Dr. Roy Plunkett. After receiving his BA, MS, and eventually Ph.D. in organic chemistry, Dr. Plunkett took a job with DuPont ™.  According to DuPont ™,  in 1938, 27-year-old Dr. Plunkett and his assistant, Jack Rebok, were experimenting with alternative refrigerant, tetrafluoroethylene (TFE). Dr. Plunkett subsequently created around 100 pounds of TFE and stored the gas in small cylinders.

The Teflon™ trademark was coined by Chemours and registered in 1945; the first products were sold commercially under the trademark beginning in 1946. Applications and product innovations snowballed quickly. Today, the family of Teflon™ fluoropolymers from Chemours consists of PTFE, the original resin; FEP, introduced in 1960; Tefzel™ ETFE in 1970; and PFA, in 1972. They discovered that the TFE gas inside had polymerized into a waxy white powder, polytetrafluoroethylene (PTFE) resin.

Three years later, Teflon™ was patented and trademarked. Four years after that, Teflon™ first began being sold, initially only used for various industrial and military applications due to the expense of producing TFE. Dr. Plunkett’s roommate in college, Paul Flory, went on to win the Nobel Prize in chemistry in 1974.
