Southwest Impreglon has expanded its line of VICTREX PEEK-based coating systems to include thin-film dispersion formulations. Previously, VICTREX PEEK, a semi-crystalline thermoplastic and member of the polyaryletherketone (PAEK) family, was only available for application as a thick film layer of (15-25) mils.

VICTREX PEEK-based coatings are durable, impact resistant and pin-hole free with outstanding chemical resistance with a continuous operating temperature of (500F(260C), UL746). The new dispersion formulations now allow for VICTREX PEEK polymer to be applied in thinner coating layers of (1.0-1.5) mils thick, while lending themselves for application on more complex metal parts with closer dimensional tolerance.

When asked how these coatings compare to fluoropolymer coatings of similar film thickness, George Butler, principal and chemist for Impreglon said “All end-use applications are different, but VICTREX PEEK polymer’s excellent fatigue resistance and general mechanical properties have been shown to outperform fluoropolymers, while the chemical resistance is vastly superior to metal components for such applications. And since we are able to formulate VICTREX PEEK with other polymers and additives, we can further improve or incorporate certain desired characteristics for our customer’s end-use applications. We have at least seven specially formulated blends that we are currently applying and the number continues to grow as we find new applications and develop new formulations to meet our customer’s needs.”

VICTREX PEEK-based coating systems currently being applied by Southwest Impreglon are shown in the chart above.
