Excalibur®
Overview
Excalibur is a fluoropolymer coating system reinforced to survive demanding industrial applications. Why is it so much better than traditional coatings? Because it is reinforced externally with stainless-steel alloy.
Fluoropolymer coatings offer valuable benefits for thousands of industrial applications. But, fluoropolymer coatings are organic and, by definition, soft. So durability is not inherent to them.
In addition, they are coated over a substrate with no more than surface cleaning and, frequently, abrading. So the coating remains separate from the substrate, simply layered over the surface.
As a result, conventional coatings wear quickly, losing the low friction, release and corrosion resistance so important to applications such as industrial bakeware, copy rollers, molds, etc.
That’s why Whitford developed Excalibur.
Excalibur is not just a fluoropolymer coating. It is a unique reinforced system. What makes it different from — and superior to — all conventional fluoropolymer coatings is its remarkably superior resistance to wear and to all forms of abrasion.
Excalibur is effective on equipment used in food processing plants

1. The surface of the substrate is grit-blasted with an abrasive to roughen it, so other elements in the Excalibur process adhere to it better.
2. Then, the most important part: white-hot particles of a special stainless steel are sprayed onto the roughened surface.
3. The particles cool and harden, bonded to the surface, forming a series of “peaks and valleys” that provide a permanent base for the nonstick coatings.
4. Several (2 or 3) coats of tough fluoropolymers fill the “valleys” and cover the “peaks,” held permanently in place by the special stainless-steel “peaks”.
