The way to get the corrosion protection you want without paying the cost of stainless steel is called Xylan fluoropolymer coatings.
 

1. Resistance to rust/corrosion: Steel fasteners coated with Xylan over a zinc pretreatment provide corrosion resistance almost equal to that of stainless steel. (They last as long as 2,500 hours in ASTM B-1 17 salt-fog tests with less than 15% red rust.)
   
   But excellent resistance to salt-foq' corrosion is only the first of many reasons to specify Xylan fastener coatings. Here are some of the others:
    

2. RESISTANCE TO GALVANIC CORROSION: Galvanic corrosion is a menace when two metals that are far away from one another on the electromotive (galvanic) scale are joined by a conductor such as moisture. That's frequently what happens when stainless-steel fasteners are used in combination with ductile iron, so often employed in waterworks pipes and fittings. In fact, some suppliers of these products will not warrant their items if stainless-steel fasteners are used.
   
   Xylan coatings reduce this corrosion. They also have a dielectric strength from 500-1,200 volts per mil (which inhibits galvanic corrosion).
    

3. COST: Compared to stainless steel, Xylan coatings can save significant amounts. For example:
    

   4"-12" steel fasteners coated with Xylan cost 15-20% less than stainless-steel fasteners. 14" -36" steel fasteners coated with Xylan cost 55-60% less than stainless-steel fasteners.

4. CONTROLLED TORQUE: Xylan coatings are engineered with PTFE for lubrication, which allows precise and uniform make-up torque. (Stainless steel fasteners are prone to galling and often seize before reaching the required preload.)
    

5. EASY REMOVAL OF NUTS: The lubricity of Xylan coatings makes removing nuts easy - even after many years of use.
    

6. WIDE RANGE OF OPERATING TEMPERATURES: Xylan coatings operate easily from -425'F 1255'C to +550°F/290°C.
    

7. UV-STABLE: Some Xylan formulations have superb resistance to ultraviolet light.
    

8. Resistance to hot soil: Xylan helps protect fasteners from corrosion caused by hot soils and most common chemicals.
    

9. Easily applied: Xylan can be applied by conventional spray, HVLP electrostatic and dip/spin, making Xylan cost-effective for any size item, from large fasteners to small O-rings.
    

10. FDA-acceptable: Many Xylan coating formulations comply with Food & Drug Administration regulations.
     

11. Color coding: Xylan coatings can be easily color-coded for specific applications (to avoid possible confusion).

IMPORTANT:
For maximum performance. Xylan coatings require the equipment, experience and skills of a professional applicator. We offer a list of approved applicators around the world and will send you a copy if you contact us (see below).
