Treatments vs Coatings

There are two questions customers almost always ask our e9 sales team when they introduce e9 Pro Metal Treatments: 

1. Is it like RainX® on my truck? 

2. Is it like Teflon?

The simple answer to both questions is NO. Rain-X® and Teflon® are coatings. e9 Pro Metal Treatments are surface treatmentsThe difference may sound subtle, but it is HUGEespecially, when applying the material on valuable and sensitive measurement devices or precisely-machined parts. 

What Is the Difference Between a Coating and a Surface Treatment?
First, when you apply a coating, you create a new surface. The surface properties are that of the coating, not the base material. This means that any area left uncovered, even a pinhole, is a likely spot for corrosion or buildup to start. In even slightly abrasive environments, this spot becomes the failure point for the surface to break down or delaminate, requiring potentially expensive repairs.  

Second, coatings are thick. Although a few microns may seem thin, this small thickness can adversely affect the operational tolerances of machined pieces. Valves may no longer seat properly, devices designed with specific mechanical frequencies may not perform at expected levels, orifices with extremely tight tolerances may no longer meet standards. 

Lastly, you must apply coatings in controlled environments. To achieve good bonding and uniform thickness, manufacturers typically apply coating in a controlled environment within a factory. Rarely, do field personnel apply a coating in a field setting and very rarely do end users reapply coatings after they have worn off. 

A surface treatment is completely different. A surface treatment changes the properties of the substrate, without changing its mechanical, electrical, or optical propertiese9 Pro Metal Treatments change the surface energy of a metal surface (the ability of a material to bond to the surface), so buildup doesn’t bond to the surfaceand instead continuously sloughs away during normal operation.  

e9 Pro Metal Treatments create a strong physical bond with the treated substrate and, therefore, do not delaminate. The top layer of the metal must physically wear away to remove the treatment. This means that in low abrasion environments, the bond will last an extremely long time.  

When applied to a surface, e9 Pro Metal Treatments are thinonly 3 – 10 nanometers thick. This is exponentially thinner than even the tightest machined part specifications. Valves seat properly, devices perform at expected levels, orifices with extremely tight tolerances meet standards, and sensitive instrumentation operates as designed.  

Lastly, you can apply e9 Pro Metal Treatment easily in a factory setting, as well as have the treatment reapplied by a service company or field crew to extend equipment performance. 

In summary, there is a big difference between a coating and a surface treatment. A surface treatment extends the life and performance of highly engineered and high performing devices, while allowing equipment to operate as designed.
