In today’s world, as in the past, high-performance coatings are in demand for use in many areas. One of the first of these fluoropolymers was discovered by accident by scientist and chemist Roy J. Plunkett in 1938. Plunkett was an employee of DuPont for 58 years and is credited with discovering the non-stick coating known as Teflon, which is made using the chemical polytetrafluorethylene (PTFE).
About Fluoropolymer Coatings
Fluoropolymer coatings blend fluoropolymer lubricants and resins. The non-stick properties of the coating protect surfaces from chemical damage and corrosion and make them resistant to high temperatures that support thermal stability.
While fluoropolymer coatings were, and still are, a popular choice for cookware, the coating was not widely used for industrial purposes. This has changed with the implementation of additional processes that have enhanced and improved coating capabilities.
Excalibur Fluoropolymer Coatings
There is a high-performance coating available called Excalibur. At Sun Coating Company, we offer this anti-stick coating that goes above and beyond the standard fluoropolymer product. What makes this coating superior to conventional non-stick coating is its external-reinforced coating. This is accomplished through a combination of stainless-steel alloys combined with polytetrafluoroethylene (PTFE-rich) coatings. PTFE is also known as Teflon.
The toughness and hardness provided by the stainless-steel plus PTFE’s non-stick properties have supported the development of Excalibur to be used for heavy industrial purposes. The coating has earned the distinction of being the most wear-resistant of PTFE coatings.
Excalibur Coating Process
The process that Excalibur goes through to achieve its reinforced coating is straightforward. The initial substrate (material) is prepped with an abrasive to roughen the surface so elements within Excalibur’s coating will adhere to the surface better.
The next step involves stainless steel particles that have been heated to extremely hot temperatures and are then applied to the surface via spraying. As the steel particles cool down, they will naturally harden, melding into the surface of the substrate/material. As the particles meld onto the material’s surface, they form what are referred to as “peaks” and “valleys” versus creating a smooth surface. This provides a strong base that will support the nonstick coating.
In the next step, the material receives its first coat of nonstick, which begins to fill the “valleys”. As more nonstick is applied to the material, both the “valleys” and the “peaks” are covered, resulting in material coated in exceptionally strong nonstick held firmly in place by the “peaks” of stainless steel.
The benefits of Excalibur include:
- Durability
- Resistance to corrosion
