Anti Corrosion

Services / Anti Corrosion

Harsh environmental conditions such as high humidity, extreme temperatures, salt, hydro-carbons, and sand often cause costly secondary power system corrosion and resulting damage.

Corrosion Resistance

SurfTec’s corrosion resistant coating can be readily applied to a wide array of metallic substrates such as aluminum, magnesium, carbon steel, stainless steel, as well as anodized/alanine metals used in gearboxes, covers and other secondary power system parts.

Strong Surface Adhesion

Our coating offers a thin, light-weight, permanent coating that requires no replenishing and is designed to allow sufficient corrosion protection necessary to last numerous overhaul cycles.

Chemical Resistance

 

SurTec’s coating is chemically inert, withstanding exposure to harsh highly acidic and basic chemical conditions and aggressive chemical cleaning procedures.

Durable

 

SurfTec’s coating yields a robust, protective coating that can extend the lifecycle of highly complex and costly parts. Tribologically, SurfTec’s coating offers a wear-life greater than any other state-of-the-art fluorocarbon coating.

Low Friction

 

 

Our coating exhibits one of the lowest coefficients of friction (COF) of any known solid. In fact, it exhibits the same COF as virgin PTFE without the high wear rate that limits the use of various PTFE composite coatings.
